Every one goes through on Firmware cannot detect whether a switch snoops, so **multicast is never an automatic upgrade here**. sACN multicast is an opt-in for someone who knows their switch, and unicast stays the portable default. What firmware can detect is a network that drops multicast altogether, the access point or switch that forgets a group. Discovery is the probe, since every device both sends and receives there. For two minutes after boot, presence goes out both ways with each copy marked. Three broadcast copies in a row from one peer, with no multicast copy between, prove the group does not arrive, even where it once did. That sets one flag, and from then every occasional multicast send adds a broadcast copy: presence and OSC feedback. A steady stream never does, light or audio, since a broadcast copy per packet would load every device on the LAN. An E1.31 multicast output says so on its card instead. A multicast copy arriving from any peer clears the flag again. -A network can also forget one member while others keep hearing.

So a socket that joined a group and hears nothing for 3 seconds joins again, at most every 3 seconds, which re-announces the membership. Every multicast receiver gets it from the platform socket: audio, OSC, discovery and Network Receive, which re-joins a large set one group per read so no read pays for all of it. + +An E1.31 receiver joins one group per universe, so a large layer asks for many. The network stack caps memberships at 16 in all on the ESP32 and 8 groups on the Teensy, shared by every socket. Network Receive's card names the universes multicast reaches and leaves the rest to unicast. A layer that takes the whole table leaves none for a service joining later, so audio sync or OSC feedback then says unicast only on its own card. The ESP32's built-in Ethernet MAC adds a narrower filter of 8 address slots, which the platform manages: [the mechanism](https://github.com/MoonModules/MoonLight/blob/main/src/platform/esp32/platform_esp32.cpp) is the `@technical` section "The internal MAC passes all multicast once its filter overflows". The W5500 and the Teensy's MAC have no such slot limit. Network-based drivers (ArtNet, E1.31, DDP) pace their output with a **non-blocking elapsed-time gate**, never a blocking wait (no `delay`/`vTaskDelay`, that would stall the single-threaded tick, the hot-path rule). The gate is the `lastSendTime`/`millis()` pattern: `if (now − lastSendTime < interval) return;` early-exits the tick so every other module's loop keeps running, exactly how FPS limiting works (`NetworkSendDriver`, `fps` control). **Frame-rate pacing is required** and implemented this way. **Inter-packet pacing**, spacing the universes within one frame, uses the same non-blocking gate where a receiver drops packets under a burst. It is off by default, since the bench ArtNet matrix test runs clean while bursting the universes, so it is added only when a target requires it, never as a busy-wait between packets. ## Multi-device sync diff --git a/docs/friend-repos/FastLED-FastLED.md b/docs/friend-repos/FastLED-FastLED.md index e9544ff05..625db3a59 100644 --- a/docs/friend-repos/FastLED-FastLED.md +++ b/docs/friend-repos/FastLED-FastLED.md @@ -1,6 +1,81 @@ # FastLED: monthly activity digest -What landed on [FastLED](https://github.com/FastLED/FastLED)'s main branch, month by month.

Two threads: the ESP32 platform layer is cut loose from the Arduino core piece by piece, and the ESP8266 gets a week of native drivers. + +**New** + +- ESP32: clocked SPI chipsets (APA102, SK9822, WS2801) get a real DMA burst instead of one polling transaction per byte, closing a 2024 report (#1609), and an explicitly chosen SPI host is honored for clocked LEDs, so output no longer depends on `addLeds` order (#4864). +- ESP32: Arduino's SPI and LittleFS are optional providers, an unused `Serial0` stays out of stock Arduino-ESP32 images (#4892), the native UART console stays out of output-only builds, the legacy RMT4 backend is selectable again with nonblocking output, and IDF 4.4 capabilities are normalized so RMT and WiFi are no longer silently disabled. +- ESP8266: native HSPI output for clocked chipsets (APA102 had been bit-banged at 1.4 Mbit/s, #4925, and the 2022 "too slow data rate for dotstar" report #1443 closes with it), an I2S output engine, an I2S-based `fl::RxChannel` input, a UART WS2812 engine selected as `Bus::UART`, OTA through ArduinoOTA, automatic embedded LittleFS, and `fl::Bus::AUTO` resolving on the chip. +- The `FASTLED_ESP8266_UART`, `FASTLED_ALL_PINS_HARDWARE_SPI` and `FL_ESP8266_EMBEDDED_FS` defines are retired in favor of template selection, and a lint flags any new driver-enabling define. +- Pull requests get a per-target memory usage report, and a no-Serial Blink scorecard per board is recorded as the new footprint baseline (#4760). +- The fastled.io documentation site moved to its own repository and the generated `gh-pages` history is purged from the main repo, so a clone no longer fetches about 500 MB of generated pages (#4878). + +**Fixed** + +- 3.10.7 and 3.10.8 fail to compile on ESP32-C3 and C6 ("different exception specifier", #4869, #4924, #4964): fixed on master with a lint so it cannot return, shipping in 3.10.9. +- Arduino Nano ESP32 compiles again (pin functions are shielded from the board's pin remap macros, #4914), and the remaining compile warnings from #4837 are cleared. +- AVR Uno: `Servo.h` and `FastLED.h` together no longer collide on the Timer1 vector (#4836). +- ESP32: an idle SPI bus or a cached RMT channel whose pin another driver took is rebuilt rather than losing the pin (#4905, #4907), and the S3 loopback capture no longer stops at 200 edges. +- ESP32-S3: discovery JSON serialization no longer crashes under a constrained heap. +- `fl::unordered_map` keeps about 1 KB of rehash scratch off the stack, which overflowed the ESP8266's 4 KB loop stack. +- The never-used ESP-DSP FFT adapter is removed; the tested FFT stays. + +**Watching** + +- The flash regression against 3.10.3 is not closed: #4707 (2.5x on 3.10.6) stays open with the optimization parked on a checkpoint branch (#4771), and a 3.10.8 measurement still shows 107% more flash and 37% more RAM (#4870). +- A proposal to replace Arduino-ESP32's startup on stock cores so `Serial0` is never linked (#4911) awaits a maintainer decision, and an audit to retire the legacy SPI output paths where the Channel API is the default (#4928) is open. +- ESP32-P4: PARLIO emits nothing and LCD_RGB capture truncates in the loopback bench (#4669) is still open. +- The proposed "FastLED Reciprocal License" (#4046) is still open; `LICENSE` on master is still MIT. + +_Auditability: 179 commits on `origin/master` with author-date 2026-10-01..2026-10-31 via `git log --first-parent` (newest 5bf59bfa19, oldest 696faa1de4; the first-parent view counts 176 by committer date), split at the three releases cut from `master`: 30 up to 3.10.6 (ebf8c2823c, published 2026-10-04), 54 to 3.10.7 (6062bee6f2, 2026-10-10), 23 to 3.10.8 (d7402f1294, 2026-10-17), 72 after.

This is a **fork of this project** building a commercial product on it: **HELIO**, a physical "infinity sphere" lamp (a warm-white 3000 K RGBW strip inside a clear acrylic shell).

This is the personal fork of upstream [wled/WLED](https://github.com/wled/WLED) by Blaž Kristan (blazoncek), a long-time WLED core developer; the fork's builds call themselves "WLED-BB" and track the 0.15 line. It carries his own work ahead of or apart from upstream: segment blending modes and transitions, an alpha (transparency) color channel, bus-manager and LED-driver rewrites, HUB75 matrix support, memory tuning for large installations, and many effect rewrites. Several of these are later offered upstream as pull requests. **Branch note.** The fork's default branch is `stable`, a release line that has 6 commits in the whole window (2025-12-31 and 2026-01-03, the "WLED-BB 0.15.2" release and four follow-ups). All day-to-day work lands on `dev`, so the months below summarize `dev` (first-parent view).

Sibling digest for v1: [hpwit-ESPLiveScript.md](hpwit-ESPLiveScript.md). +## October 2026 + +The rewrite's heaviest month so far: the language grows toward C, a fuzzer hardens the compiler, and generated code closes in on native speed. The details follow below. + +**What script authors gain** + +- `switch`/`case`/`default` works as in C (fallthrough, `break`, nested switches, `#define`d and negative case values, errors for duplicate cases or a second `default`), and a bare `{ }` block is a statement. A `SwitchCase` example shows it. +- `ffloat`, a 32-bit fixed-point type (Q16.16, about plus or minus 32768 in steps of 1/65536) written like a float: literals and constant subexpressions fold at compile time, and the arithmetic compiles to integer instructions. Multiplying or dividing by an integer, and dividing by a power of two, take fast paths. The README says to watch intermediate values against the range. +- `safe_mode` works. The v1 port could not even assemble; now an indexed store into a global or external array with declared dimensions is bounds-checked, and a failed check stops the script, records the array, size and index, reports it (a console line or an `onScriptRuntimeError` hook) and unwinds back to the host call, which returns false. Pointers and unsized arrays stay unchecked. +- `pause()`, `restart()`, `kill()` and `state()` control a script run with `executeAsTask()`; a task whose function returns marks itself stopped instead of deleting itself, so no control call acts on a vanished task. +- `char *` arguments work: a `char *` variable, parameter, array or call result can be passed to a function (only string literals matched before). A `StringFunctions` example shows strings in and out of script and host functions. +- `_handle_` (the running executable's address) is declared in every script, so a script compiled through the raw parser path can register callbacks; the `PinInterrupt` example (a GPIO interrupt calling a script function) is ported from v1. +- `%` is signed, as in C (`-7 % 3` gave 0 before), and uninitialized globals start at 0 instead of leftover heap contents. +- GPIO registers can be bound as script variables, so a script sets pins up and toggles them with single stores: the `DirectGPIO` example builds for ESP32 and ESP32-S3 with no address or chip named in the script, and `DirectGPIOSpeed` measures 9.9 MHz on the pin, script and native within half a percent of each other. + +**Fixed** + +- Reload elimination dropped a load after its base register changed, so `line1[i + 1] + line1[i]` counted one neighbor twice (found writing the `GameOfLife` example). +- `if / else if / else` chains attached the trailing `else` to the first `if`, and the dangling else in `if (a) if (b) x; else y;` attached to the outer statement. +- Ternary expressions: `a < b ? x : y` parsed as `a < (b ? x : y)`, the result register was not reserved (`(c ? 1 : 1) * 6` gave 36), and a store's address load could land inside one branch. +- Call arguments overwritten in many shapes: a call inside an array-element store, a call in an argument to the left of an already placed argument (`f(f(5, 1), 8)` passed 1 for the 8), the fifth and sixth arguments of a nested call, arguments held while later ones compute (now pushed on the stack), a live `a10` temporary around a nested call, `printfln` arguments overwritten by a later argument's call, and register locals loaded through a scratch register that already held an earlier argument. +- A temporary live across a call (`fib(n-1) + fib(n-2)`, `20 + rand(200)`) was never saved while the callee ran. +- Frames reserved 16 bytes above the locals where the register-window overflow handler needs 32, so stack locals were overwritten once a call chain got deeper than the register window. +- Xtensa's short conditional branches have 8-bit offsets for most forms, so any `if` or loop body longer than about 128 bytes could jump into unrelated code. The assembler now relaxes an out-of-reach branch into its inverse over a jump and retries until everything fits. This was the cause of every crashing fuzz seed. +- `==` and `!=` against a constant were inverted in a long `if` body and in a loop's bottom-tested condition: `if (a != 1)` with a long body ran exactly when `a == 1`. +- The first global initializer in a script stored its value before loading its address. +- `++` and `--` on an int struct member inside a method stepped by 4 (taken for a pointer); this affected every script, float and int alike. +- Multi-dimensional indexes used fixed scratch registers, so a call or a 2D read inside an index lost the partial sum. +- Several copy-propagation and dead-copy cases in the optimizer dropped a copy that was read again later, or kept one after its source was overwritten. +- Function records in the binary header: a struct method's record carried a copy of whatever line came next, and per-function compile separated a function's `.global` and `.var` lines (`MultiEffectController` is 265 bytes smaller). + +**Faster generated code** + +- Hot locals live in registers: a pass promotes a function's most used frame slots to registers the function never names (ints to the call-surviving `a4..a7`, floats to `f3..f12` with saves around calls), weighting loop accesses 8x per nesting level. One 128x96 Mandelbrot frame on an ESP32 at 240 MHz: float 86.8 to 66.9 ms. +- Values that live across a call sit in spare window registers instead of frame slots: `fib(40)` goes from 26.94 s to 21.72 s (native 16.96 s, so 1.28x native instead of 1.59x). +- Multi-dimensional array strides fold into shifts and scaled adds instead of a `movi` plus `mull` per dimension, and leftover register copies fold into their readers. +- A last pass hoists loop-invariant loads (array addresses, constants) out of loops, gives the remaining frame slots any register free over their lines, and tidies by liveness. Game of Life 128x128 over the month: 15.24 to 8.08 ms per generation (v1: 14.67, native 5.95); Mandelbrot float 62.3 ms, `ffloat` 50.0 ms, frames identical to native. +- `ffloat` speedups: consecutive multiplies share one shift-amount register, small constants load as `movi` plus shift, division by an integer is an inline `quos`, division by a power of two is a shift. BouncingBalls with 60 balls: `ffloat` 10.83 to 6.51 ms per frame (float 7.80). +- Loop heads and jump targets get a `nop.n` when their first instruction would straddle a 4-byte fetch boundary. + +**Compiler memory** + +- The compiler's peak heap is roughly halved: functions compile as soon as they are parsed and their syntax tree is freed, tree nodes come from a pool, assembler lines live in one packed array, and branch relaxation runs before assembling so the text is assembled in one pass. The 730-line `MultiEffectController` script now compiles on an ESP32 without PSRAM (about 207 KB used of 230 KB free); the host model drops from 453 KB to 238 KB and fails above a 256 KB budget. + +**Verification** + +- A differential fuzzer generates random programs in the subset of the language that is also C, runs each compiled by ESPLiveScript2 under QEMU and as C on the host, compares the traces and reduces a failure to a few lines automatically. Its first run found seven compiler bugs; every reduced program lives in `test/fuzz/regressions/` (39 by month end) and runs as a regression suite. +- A frame-by-frame effects suite compares the procedural effect scripts and the fixed-point Mandelbrot against C versions under QEMU, and a full-system tier builds real sketches with `arduino-cli` and boots them under QEMU's esp32 machine (the `SafeModeTest` sketch covers overruns, negative indexes, recovery and the hook). +- The host run-large test tracks every allocation the compiler makes and models the ESP32's per-block cost. +- Still open per the commits: an intermittent "Cache disabled" panic during the first on-device compile, about one boot in eight, under the full-system test. + +**Examples and documentation** + +- New examples: `GameOfLife`, `ProceduralEffects` (plasma, fire, Voronoi, mandala and spinning squares on a 128x96 matrix, each verified byte for byte against a C reference, with frame images), `MandelbrotFixedPoint`, `MandelbrotFfloat`, `BouncingBallsFfloat`, `FloatVsFfloat`, `MandelbrotCompare` (native float and fixed against script float and `ffloat`, timed with checksums), `SafeMode`, `SwitchCase`, `StringFunctions`, `PinInterrupt`, `DirectGPIO` and `DirectGPIOSpeed`; 34 in all. +- The README is rewritten in the style of v1's: shorter, example-first, with board measurements in place of QEMU projections. + +No issues were opened or closed.

One that asks whether MoonLight has the same defect is checked in the code: found, it is fixed; absent, it is dropped. Any other joins the card, plan or issue that already covers it. With none, it becomes a backlog card when it removes more than it adds, is the textbook answer, fits the architecture and someone wants it; otherwise it is dropped. Study to think, write fresh, never copy. -Reading across the friend-repo digests, the themes the wider ESP32-LED ecosystem converged on over this release cycle (Sept 2025 → June 2026): +## October 2026 -- **ESP32-P4 / S3 parallel output.** FastLED poured effort into the PARLIO and LCD_CAM drivers (P4/S3 parallel LED output, big encode speedups); NightDriverStrip added custom RMT output; hpwit's I2SClocklessLedDriver pushed IDF-5.5 + arduino-less-ESP-IDF support for its I2S/LCD DMA driver (the canonical implementation of this technique), and troyhacks ran ESP32-P4 bring-up branches. The frontier is parallel, DMA-driven output on the newer chips. -- **PSRAM strategy is unsettled everywhere.** All four wrestled with PSRAM this cycle, WLED-MM moved preview buffers into PSRAM, NightDriverStrip did a full PSRAM-default reversal (then tuned the threshold), WLED added S3-no-PSRAM builds. Nobody has a clean answer; the cache-disabled-during-flash hazard recurs across repos. -- **Audio-reactive maturing.** FastLED added a silence-gate + ESP-DSP FFT backend; WLED-MM and WLED both refined audio sync and auto-disable-during-realtime; NightDriverStrip modernised its SoundAnalyzer/FFT. Audio-reactive is table stakes now, and the polish is in *not* reacting to noise/silence. -- **The FastLED dependency question.** WLED merged a *full FastLED replacement* (its own color/math); MoonLight already made the same call (own color math, no FastLED in core). Two independent projects concluded the dependency wasn't worth it. -- **UI as a firmware-driven consumer.** Both WLED and NightDriverStrip pushed toward "the official UI knows nothing the firmware doesn't publish over the wire", exactly MoonLight's MoonModule-driven, no-hardcoded-knowledge UI principle. Convergent design. NightDriverStrip's **2.0.0** (June 2026) crystallised this: a brand-new web UI, a browser-based installer, and settings (like strip type) moved from compile-time to *runtime-selectable* on the device, the same "reconfigure live, no reflash" direction MoonLight builds around. -- **Effect velocity.** WLED and WLED-MM shipped many new effects (PacMan, Color Clouds, Shimmer, the user_fx pack); new effects remain the most visible user-facing output. -- **Display / HDMI output beyond LED strips.** troyhacks ran a cluster of branches probing HDMI video output and large hardware panels (WaveShare 10.1″, M5Stack, ESP32-P4 panels), driving *displays*, not just addressable strips, off the same firmware. -- **On-device live scripting.** hpwit's ESPLiveScript compiles small C-like effect scripts that run live on the ESP32 with no reflash, a different answer to effect authoring than C++ recompilation or a fixed effect table. +### Cross-repo trends -## What these projects do that MoonLight doesn't (yet) +- **Audio measurement moves past the plain FFT.** troyhacks reads 31 third-octave bands from biquad filter banks, checked bar for bar against a hardware RTA; WLED moved its audio-reactive usermod onto ESP-IDF 5 with a background ADC manager; WLED-MM now follows the Audioreactive V2 usermod and its audio-driven palettes; FastLED removed its unused ESP-DSP FFT adapter. +- **Footprint becomes a release issue.** FastLED shipped 3.10.6 at 2.5x the flash of 3.10.3 and spent 3.10.7 on a memory sweep; WLED trimmed about 8 KB of flash; new-parser halved its compiler's peak heap so a 730-line script compiles without PSRAM. +- **Large panels expose effect math.** WLED fixed seven 2D effects that broke at 128 pixels wide and up, blazoncek updated four effects for large matrices, and WLED's HUB75 buffers moved to PSRAM so a 128x128 panel fits on an ESP32-S3. +- **Hardening against crafted input.** WLED fixed a security advisory in playlist JSON and is weighing hardening every network input; blazoncek discards incomplete or oversized UDP packets; new-parser's `safe_mode` bounds-checks script arrays. +- **The ESP-IDF 5 and 6 migration continues.** WLED keeps nightly builds off while `main` migrates; FastLED builds the IDF 6 release candidate and cuts its ESP32 layer loose from the Arduino core; outside pull requests bring I2SClocklessLedDriver to IDF 6. +- **Verification by execution.** new-parser's differential fuzzer runs random programs under QEMU and as C, troyhacks added a checker that reads a running board's audio state, and FastLED records a footprint scorecard per board. -Observational: where the landscape is ahead of MoonLight. These are *not* commitments; real adoption decisions live on [the Project](https://github.com/users/MoonModules/projects/5), cross-referenced where one already exists. +### Candidates for MoonLight -- **A guided setup/installer wizard on-device** (NightDriverStrip's Setup Wizard, WLED's installer), MoonLight has the web installer + Improv, but no on-device first-run wizard. -- **A large built-in effect library**: MoonLight ships a focused set (concrete-first); the WLED family ships dozens. Breadth is a deliberate non-goal until the core is proven. +- **Differential fuzzing of MoonLive against C** ([hpwit-new-parser](hpwit-new-parser.md), October 2026): random programs in the C-shaped subset, compiled under QEMU and as C on the host, traces compared and failures auto-reduced; seven compiler bugs in its first run, each kept as a regression script. Builds on the QEMU tier above. +- **Bounds-checked script arrays that stop the script and name the fault** ([hpwit-new-parser](hpwit-new-parser.md), October 2026): an out-of-range index stops the script with array, size and index reported instead of corrupting memory, at one unsigned compare per indexed store. +- **A fixed-point type written like a float** ([hpwit-new-parser](hpwit-new-parser.md), October 2026): `ffloat` (Q16.16) keeps float syntax in an effect script while compiling to integer instructions; a 128x96 Mandelbrot frame takes 50 ms against 62 ms in float. +- **Bound every packet parser by the received length** ([wled-WLED](wled-WLED.md), October 2026): WLED found three over-reads in one month (playlist JSON, UDP sync, Art-Net and E1.31) where a check compared against the buffer size; worth one audit of MoonLight's DDP, Art-Net and JSON inputs. +- **Run effect tests at large panel sizes and at unlimited frame rate** ([wled-WLED](wled-WLED.md), October 2026): seven WLED 2D effects broke at width 128 and up (int8 math, infinite loops, float to uint8 casts); a 192x64 test size plus a zero frame time would pin the same class. +- **Fail the build when a board's firmware grows past its budget** ([FastLED-FastLED](FastLED-FastLED.md), October 2026): FastLED measured size per commit and still shipped 3.10.6 at 2.5x the flash of 3.10.3; MoonDeck's size ratchet records growth without failing anything. +- **Pin every third-party dependency to an exact version** ([PlummersSoftwareLLC-NightDriverStrip](PlummersSoftwareLLC-NightDriverStrip.md), October 2026): a `^3.10.1` caret range let a FastLED minor release break every NightDriverStrip build with no change in the repo. +- **Same brightness and gamma on network outputs as on wired ones** ([blazoncek-WLED](blazoncek-WLED.md), October 2026): the fork aligned its virtual bus with its digital buses; worth checking MoonLight's Art-Net and DDP outputs scale the same way as its LED drivers. +- **Measure audio bands with filter banks instead of an FFT** ([troyhacks-WLED](troyhacks-WLED.md), October 2026): 31 third-octave bands from two biquad banks, verified against a hardware RTA; input for the audio engine issue (#229). +- **Palettes driven by the audio spectrum** ([MoonModules-WLED-MM](MoonModules-WLED-MM.md), October 2026): five palettes whose colors follow the music make any effect audio-reactive without an audio-aware effect. -## Candidates for MoonLight +## September 2026 -Concrete ideas the digests surfaced, waiting for a decision.

NightDriverStrip's **2.0.0** (June 2026) crystallized this: a brand-new web UI, a browser-based installer, and settings (like strip type) moved from compile-time to *runtime-selectable* on the device, the same "reconfigure live, no reflash" direction MoonLight builds around. +- **Effect velocity.** WLED and WLED-MM shipped many new effects (PacMan, Color Clouds, Shimmer, the user_fx pack); new effects remain the most visible user-facing output. +- **Display / HDMI output beyond LED strips.** troyhacks ran a cluster of branches probing HDMI video output and large hardware panels (WaveShare 10.1″, M5Stack, ESP32-P4 panels), driving *displays*, not just addressable strips, off the same firmware. +- **On-device live scripting.** hpwit's ESPLiveScript compiles small C-like effect scripts that run live on the ESP32 with no reflash, a different answer to effect authoring than C++ recompilation or a fixed effect table. + +### What these projects do that MoonLight doesn't (yet) + +- **A guided setup/installer wizard on-device** (NightDriverStrip's Setup Wizard, WLED's installer), MoonLight has the web installer + Improv, but no on-device first-run wizard. +- **A large built-in effect library**: MoonLight ships a focused set (concrete-first); the WLED family ships dozens. Breadth is a deliberate non-goal until the core is proven. + ## Refreshing Adding a month or a new friend repo is the [friend-repos](index.md) workflow, and its prompt lives there.

Only real issues, not PRs. The commit log shows what shipped; the issues show what users *hit* and what the maintainers are prioritising, the two together are the real activity picture.

Fold the user-facing ones into the summary below (a widely-reported bug that got fixed, a feature the community is pushing for); an issue with no user-facing outcome yet is still worth a one-line "watching:" note if it signals a direction.

The goal is the best visible answer to the music: silence is dark, a quiet passage stays quiet, a loud one is loud, the bars sit balanced across the spectrum, a kick drum is found whatever song is playing, and the beat lands on the beat. The least to set follows from it, since a level that learns the song beats any knob set for one song. The analysis stays one pipeline on every board; measurement-grade accuracy (an analyzer's calibrated bars) is not the goal and goes to the backlog. - -The yardstick is music information retrieval, the field whose libraries (Essentia, librosa, aubio) describe music to a machine: loudness, spectral balance, onsets per band, and tempo with beat phase, in that order. Steps 2 to 5 build one each; step 1 makes the bands those descriptors are read from. Two things the field settles that this plan follows: a band per instrument is not a thing (instruments overlap in frequency, and separating them is a neural net on a GPU), while the drum kit does separate by range; and genre presets lose to adaptation (a floor, a gate and a gain that learn the dynamics give a quiet classical passage and a loud rock chorus the same treatment with no switch). - -## The design basis - -- **One pipeline, no engine select** ([CLAUDE.md, principle 3](../../CLAUDE.md#principles)): one analysis path, the same on every chip. -- **The textbook.** A band is the power in its slice of the spectrum, normalized so that white noise reads flat (Welch's periodogram). A noise gate opens fast and closes slow with hysteresis, as every studio gate does. Automatic gain is one offset that holds the loudest band at the top, with a fast attack and a slow release, as a compressor's make-up gain does. -- **Study, credit, write fresh.** MoonLight's audio path is its own implementation, from the INMP441 datasheet and standard DSP; the people whose thinking it studies are credited by name below and in the header's `@attribution`. -- **Measured on synthesized signals** on the desktop, then judged by eye on the bench: the product owner's eyes are the measurement for a light show. - -## What exists - -- **`AudioService`** ([AudioService.h](../../src/core/services/AudioService.h)): a 512-sample block, a DC blocker, a Hann window, esp-dsp's FFT on the ESP32 and a DFT on the desktop, a frame every 23 ms. -- **The bands** ([AudioBands.h](../../src/core/services/AudioBands.h)): sixteen log-spaced bands, each the loudest bin of its slice. Pink noise, the spectrum real music resembles, falls toward the treble on that estimator, which the learner in `BandConditioner` then corrects per band. -- **The level path**: `floor` is a silence threshold and a window bottom at once; `levels` switches between a manual `gain` and a learned window; `BandConditioner` and `LevelConditioner` learn a floor and a peak each and apply a compressor's ratio. Three mechanisms share the one job of "show the music at the right size", from three places. -- **`OnsetDetector`**: one `onset` for a hit anywhere in the spectrum, so a kick and a snare look alike. -- **The readers**: thirteen effects read `bands[16]`, the WLED sync packet carries sixteen, and MoonLive reads `audioBand(i)` and `audioPeakHz`. - -## Prior art - -Audio-reactive lighting has a lineage (WLED-SR, WLED-MM, MoonLight), and four people's thinking is weighed here, their ideas and our analysis. - -**Frank (softhack007)**, main author of the WLED-MM audioreactive usermod, who the product owner worked alongside for years: the adaptive noise gate that step 2 builds. His concept, analyzed with his permission: a standard noise gate on the time-domain level, open fast and close slow with hysteresis, keyed to a *learned* floor so it self-calibrates to whatever source is connected, with thresholds as factors of that floor rather than absolute counts. His constraints bind step 2: the gate decides "is there sound" and leaves scaling to the gain; it reads the RMS the level path already computes, so it adds no delay; the whole chain stays under 30 ms, and a 512-sample block at 22,050 Hz already spends 23 of them, so every smoother is a one-pole. - -**Troy (troyhacks)**, MoonModules: [his AudioReactive rewrite](https://github.com/troyhacks/WLED), commit `ed544259` of 2026-10-25, on an ESP32-P4, checked against a hardware analyzer. Most of it chases measurement accuracy (a 4096-point transform, biquad pre-filters, calibration from a measured impulse response, 31 third-octave bands, self-tests at boot), which this plan leaves to the backlog. Two decisions carry over: - -| Decision | What it does | Why it matters here | -|---|---|---| -| **A unit contract** | Every band is a power density normalized by the sample rate and the window's power, so white noise reads flat by definition and pink noise falls 3 dB an octave | A test can assert "balanced bars" instead of a learner correcting for the estimator | -| **Four quantities, kept apart** | The level is the RMS of the fresh audio in dB; the floor snaps down at once and creeps up with a 10 s time constant, only while the level sits within 3 dB of it; the gate opens at `squelch` dB above the floor and shuts 4 dB lower; the AGC is one dB offset holding the loudest band at 0 dB, 20 ms attack, 1,500 ms release, frozen while the gate is shut | Nothing reads its own output, so the deadlocks of one number doing four jobs are impossible; our three mechanisms approximate this from three places | - -A later version, described on Discord on 2026-10-28 and unpushed, replaces the FFT with filter banks, which time a hit within a tick rather than within a 23 ms block; it changes no step here and is [the trial in the backlog below](#backlog), run once the steps give it a bench. - -**LedFx**, the host-side effect engine whose whole purpose is audio reactivity: its mel-spaced bands and per-band asymmetric smoothing, reached independently of the WLED lineage. Step 1 keeps log spacing (mel and log coincide above 1 kHz and the sixteen readers depend on the layout); the asymmetric smoothing is the attack and release step 2 gives the gain. - -**Damian (DedeHai)**, WLED: the fixed-point FFT for chips without an FPU. Every MoonLight audio target has one, so the float transform stays; the int16 path is the lever if a C3 ever analyzes audio. - -## Steps - -Each step ends in a desktop test and a bench look. - -### 1. Balanced bars by construction ⏳ - -- A band is the power summed over its slice, normalized by the sample rate and the window's power, in `AudioBands.h`; the loudest-bin estimator goes. -- Desktop tests: synthesized white noise reads every band within 1 dB of flat; pink noise falls 3 dB an octave; a sine lights one band; the dominant peak reads as before. Flux and onset are recomputed from the new bands, and a synthesized kick still fires `onset` while steady pink noise does not. -- Bench: pink noise from a phone through the microphone, and the bars sit level. - -### 2. One level path, no knobs ⏳ - -- Four quantities, as the prior art has them: the level in dB, a floor that snaps down and creeps up only near the floor, a gate with hysteresis that opens fast and closes slow (Frank's adaptive gate, under his constraints above; the silence threshold `floor` already gives is its set half, the learned floor its adaptive half), and one dB offset holding the loudest band at the top, frozen while the gate is shut. -- A setting stays when the bench shows a better result with it than without, and goes when the automatic path matches it. `floor` stays, the one setting a room may need, with a default that suits a MEMS microphone; `levels`, `gain`, the conditioner's ratio and maximum gain, and the two learned tables are each tried against the automatic path on the bench. A choice that belongs to an effect (which signal it follows: a band, the bass, the onset, the beat) sits on the effect's card, part of the effect rather than a tuning. -- Tuned in a quiet room first, then in a noisy one with a varying low-frequency ambient, the case that made the earlier self-calibrating prototype hard to settle. -- The card shows the four quantities, so a gated room reads as "gated at −52 dB" rather than as a dead audio path, the bug report a high default floor earns today. -- Bench: silence is dark, a quiet passage stays quiet, a loud one is loud, a song that starts soft and ends loud fills the rig at both ends, and the StadBeest's eyes follow on the bench network. - -### 3. The kick is found in any song ⏳ - -- Three sums beside the sixteen bands, each a `uint8_t` 0 to 255 on the bands' scale: the power of the FFT bins whose centers fall in 20 to 150 Hz, 150 Hz to 2 kHz, and 2 kHz to Nyquist, normalized as step 1 normalizes a band, so a sum reads on the same dB scale as a band, so an effect keyed on the bass finds the kick whichever band it lands in; MoonLive gains `audioBass`, `audioMid` and `audioTreble`. -- Bench: `BeatRipplesEffect` keyed on the bass sum through a kick-drum track. - -### 4. A kick and a snare look different ⏳ - -- An onset per range (low, mid, high) from the sums of step 3, each with the flux-against-its-mean decision `OnsetDetector` already makes; `onset` stays as the any-hit signal. Moved here from [the live-performance plan, step 5](Plan-20261013%20-%20Audio%20reactive%20live%20performance%20(0%20of%207).md), which keeps the drum-trigger route. -- Desktop test: a synthesized kick fires the low onset and not the high one; a synthesized hi-hat the reverse. -- Bench: a drum track, the kick splashing from the floor and the hi-hat sparkling at the top, on one layer each. - -### 5. The beat lands on the beat ⏳ - -- Tempo and beat phase from the onset curve, the standard algorithm (Ellis, *Beat tracking by dynamic programming*, 2007: autocorrelation of the flux history over the last few seconds picks the tempo in 60 to 200 BPM, and the phase that lines up with the recent onsets picks the beat). The frame carries `bpm`, `beatPhase` in 0 to 1 and `beat` for the block the phase wraps. MoonLive's `audioBeat`, a level-above-its-average guess until now, returns the tracked beat, and `audioOnset` and `audioBpm` are added. A reactive effect trails a hit by a block; a beat-synchronous one fires on it, and knows when the next one comes. -- The beat phase is what the live-performance plan's `MidiFrame` takes from a MIDI clock when one runs; the audio estimate fills the same field when none does, so an effect reads one phase from either source. -- Desktop tests: a synthesized click track at 120 BPM reads 120 within 1 BPM and `beat` fires within a block of each click; a track that steps to 140 BPM follows within four beats; silence reads no tempo. -- Bench: `BeatRipplesEffect` on `beat` instead of `onset` through a steady song, the ripples on the pulse rather than on every hit. - -## What an effect reads - -[`AudioFrame`](../../src/core/util/AudioFrame.h) is the whole contract: one flat struct per tick, every field a small integer, read through `AudioService::latestFrame()` by an effect and through builtins by a MoonLive script. Today it carries the level (raw and smoothed), the sixteen bands (raw and with meter ballistics), the dominant frequency with its magnitude, the flux and `onset`. So an effect sees volume, a spectrum and "a hit happened"; twelve of the seventeen audio effects draw the bands, the rest read the level or `onset`. The plan widens the struct and nothing else: - -| Step | New fields | MoonLive | -|---|---|---| -| 1, 2 | none; `bands` and `level` mean what they did, read better | | -| 3 | `bass`, `mid`, `treble` | `audioBass`, `audioMid`, `audioTreble` | -| 4 | `onsetLow`, `onsetMid`, `onsetHigh` | `audioOnset(range)` | -| 5 | `bpm`, `beatPhase`, `beat` | `audioBpm`, `audioBeat` | - -A field is 0 when its source is absent, so an effect on a board without a microphone draws its idle state, as today. The new fields are local: the WLED audio-sync packet carries none of them, so a board in receive mode leaves them at 0 while it keeps its own `bandsSmoothed` across the fresh frame, and a desktop test pins both. - -## What it costs, per chip - -**Analysis is not where the frame goes.** AudioService's fixed I2S block read adds 13 to 22 µs to an average tick ([performance.md](../reference/performance.md), 2026-06-17); the 512-point FFT every 23 ms at 22,050 Hz waits for a measurement of its own. Each step keeps it that way, and its desktop test and bench run record the tick it adds. - -| Step | What it adds per block | Estimate, to be measured | -|---|---|---| -| 1 | a power sum over the 256 bins, replacing the loudest-bin search | the same loop as today | -| 2 | a few multiplies for the floor, gate and offset | negligible | -| 3 | three sums over bins step 1 already reads | negligible | -| 4 | three flux decisions | negligible | -| 5 | an autocorrelation of about 6 s of flux, some 260 values, over the 30-odd lags of 60 to 200 BPM, plus a phase fit | about 8,000 multiply-adds, under 0.1 ms on a classic ESP32 at 240 MHz, and 1 KB of history | - -**Beat tracking is cheap here because it runs on the onset curve, not on the audio.** The expensive half of a beat tracker is the onset analysis, which the FFT already pays for. A tracker gets costly when it evaluates every lag at the audio rate, or runs a dynamic program over a long history every sample; this one evaluates once per block over a few hundred values. - -**The same signals on every chip, the headroom spent on resolution.** Every chip that analyzes audio carries all five steps, so an effect behaves alike on each, as decided for the filter-bank trial. A chip with spare cycles spends them on how finely the signals are measured, never on extra ones: - -- **A 1024-point FFT for the bass.** At 22,050 Hz and 512 points a bin is 43 Hz wide, so 20 to 150 Hz is three bins; 1024 points halve the bin width, at twice the block latency. The decimated FFT in [the backlog](#backlog) is the other route to the same bass. -- **50% overlap.** A new block every 256 samples halves the onset step from 23 to 12 ms, which tightens the beat phase. -- **44,100 Hz** for the treble sum and the hi-hat onset. - -Each is chosen per chip by the platform, a default rather than a user setting, so it adds no knob. The classic ESP32 is the floor: each step is measured there first, and a step over its budget there, about 1% of a 60 fps tick, gets cheaper on that chip rather than dropped from it. - -## Effects on the new signals - -Each is a small change once its field exists, and together they are the bench for the plan, since a signal nobody draws is not verified. In the order the steps land: - -| Effect | Reads | What it shows | Step | -|---|---|---|---| -| **An audio modifier** | `levelSmoothed` | Scales any effect's brightness, speed or size with the music, so every effect in the catalog answers it without an audio variant each. The one that makes the level path visible on a whole rig | 2 | -| **`BeatRipplesEffect` on the bass** | `bass`, then `onsetLow` | Stones dropped on the kick rather than on any hit, the first effect to find the kick in any song | 3, 4 | -| **Three zones** | `bass`, `mid`, `treble` | Three colors, the bass on the floor, the mids in between, the treble at the top, breathing with their range: the spectrum reduced to what an audience reads at a glance | 3 | -| **Drum kit** | `onsetLow`, `onsetMid`, `onsetHigh` | A kick splashes from the floor, a snare flashes the middle, a hi-hat sparkles the top, each a short-lived sprite the `SpriteFountainEffect` already knows how to throw | 4 | -| **`PulseEffect` and `PaintBrushEffect` on the beat** | `beat` | One shell, one stroke, per beat instead of per hit, steady through a song | 5 | -| **Beat sweep** | `beatPhase` | A bar that crosses the rig once per beat, position from phase, the classic sweep in time that a reactive effect cannot do because it moves between hits | 5 | -| **Palette per bar** | `beat` | The palette advances every fourth beat, so color changes land on the bar line | 5 | - -The modifier is the recommended first, since it turns the existing catalog audio-reactive at once; the rest follow their steps. - -## Backlog - -On the topic and not a step. What remains here when the plan ships returns to the Project as cards, item by item, then. - -- **Analyzer-grade accuracy**, what a rig cannot show, each taken when a user or an effect asks: a transform sized by the chip (2048 points on the S3, 4096 on the P4) for two bass notes to read as two bars; a biquad pre-filter chain (rumble high-pass, anti-alias low-pass) from esp-dsp's `dsps_biquad_f32`; calibration against a measured chain and a self-test on the card. Troy's rewrite has all three, checked against a hardware analyzer. -- **Troy's band definition, for comparing the two engines (2026-11-02).** `AudioSpectrumEffect`'s sweep colors draw what WLED-MM's GEQ PPA draws, so two boards side by side differ only in their audio; a MoonLight board receiving a WLED-MM board's audio sync already shows his sixteen bands through it. Comparing our own analysis with his, and his RTA mode, needs his definition on our side: - - 31 ISO 266 third-octave bands, 19.95 Hz to 19.95 kHz, each slice the center times 2^(∓1/6), each band the power summed over its slice, as step 1 makes a band; - - the dB window auto-ranged to the loudest band, which step 2's offset is (his: a 40 dB span by default); - - one-pole smoothing per band, 8 ms attack and 60 ms release, in milliseconds so neither frame rate changes it; - - the sixteen as a subset of the 31, picked by a pattern that shifts them −3 to +3 bands (50 Hz to 12.5 kHz by default); - - a `live` flag: the 31 exist only on a board measuring its own input, never over audio sync, and GEQ PPA falls back to 16 bars without them. - - `AudioFrame` gains `rta[31]` and the flag, and `AudioSpectrumEffect` draws 31 bars while the flag is set. A like-for-like run pins every engine setting that moves the picture on both boards: the pattern, the window span, auto or fixed range, the dB reference, attack and release, the gate. -- **A second, decimated FFT for the low bands (2026-10-05).** At the default 22.05 kHz a 512-sample block gives 43 Hz bins every 23 ms, so the bands below about 130 Hz own one bin each and two bass tones a semitone apart land in the same band. A longer FFT alone buys resolution at the cost of time for every band (2048 samples: 10.8 Hz, but 93 ms). The textbook multirate answer keeps both: low-pass and decimate by 4 to 5.5 kHz, run a 512-point FFT on that for the bands under about 2.7 kHz (about 11 Hz bins), and keep the 23 ms FFT for the rest. Cost is one more 512-point FFT and a small decimation filter per block. Pinned on the desktop by two synthesized bass tones (50 and 60 Hz) landing in different bands, then measured on an S3 against the Audio module's tick time. -- **A filter bank for the bands (2026-10-28), a trial.** Troy's unpushed version computes each band as a resonator answering every sample, so a band's time resolution matches its frequency and a hit is timed within a render tick rather than within the 23 ms FFT block: sharper onsets, a better beat phase, a bass that follows a note. Sixteen second-order biquads at 22 kHz are a few MFLOPS, inside an S3's FPU and trivial on a P4, Teensy or desktop; the classic and the C3 are the question. Every device behaves the same, so this is a trial of one against the other, not a choice per chip: both behind the one `AudioFrame` with the same unit contract and the same tests, a select on the card for the trial only, run after the steps give it a bench (the synthesized tests on the desktop, onset timing on a click track, the tick cost measured on the slowest chip, and the bench by eye). Then one of the two stays, on every chip, and the other and the select go; `peakHz` keeps a transform either way. -- **More audio effects on the bands**, 2D and palette-driven frequency-reactive ones, beside [the effects on the new signals](#effects-on-the-new-signals). -- **Pin auto-scan**: detect the microphone's `sdPin` with `wsPin` and `sckPin` fixed, a noise prompt and a confirm; explicit pin controls ship today. -- **Sources beyond the I²S microphone**, each a variant behind the same platform read, the analysis untouched. The I²S peripheral already drives MCLK (`mclkPin`) for a line-in ADC. - - **PDM microphones**: the IDF `i2s_pdm` driver, a sub-mode of the same peripheral. - - **Analog line-in**: DedeHai has it on the S3 and Troy in ParrotRadio, where he recorded and played back through it. An analog path is validated by listening to it, since one that only feeds a level meter "may not be as accurate as it looks" (Troy). - - **I²C-configured codecs** (the ES8311 class): Espressif's `esp_codec_dev` component carries the register tables for many codecs, so none is hand-rolled. - - **Multi-channel front-ends**: a TDM codec (the ES7210 on the Waveshare RGB-Matrix board) or a DSP board giving one analyzed channel per instrument, the input [the live-performance plan](Plan-20261013%20-%20Audio%20reactive%20live%20performance%20(0%20of%207).md) needs for acoustic drums. -- **Desktop audio capturing what the machine plays (2026-09-29).** `platform_desktop_audio.cpp` enumerates capture devices only (`ma_context_get_devices` with null playback lists) and opens `ma_device_type_capture`, so on a Windows bench the picker offers `default` and the microphone and the speakers are absent, with no Stereo Mix to fall back on. miniaudio has `ma_device_type_loopback`, WASAPI-only, taking a playback device: enumerate playback devices too, mark them in the picker so a microphone and "what is playing" tell apart, and open loopback when one is chosen. macOS has no equivalent and needs a virtual device such as BlackHole, so the picker offers what the platform can do rather than a row that fails. A disconnected microphone jack reports a plausible level (RMS 20 to 30 at mains hum), which the status of step 2 tells from a working input. - -## Open questions - -- **Which settings stay on the card:** step 2 settles it per setting on the bench. **Recommended (2026-10-28):** the result decides, not the count; the expectation is `floor` alone, and a response-speed setting (attack and release) is the likeliest second if a bench case wins with it. -- **Whether step 2 keeps a manual mode** for a show that wants deterministic levels. **Recommended (2026-10-28):** no; freezing the floor and the offset is the deterministic mode, as a `freeze` toggle, if a show asks. - -## What it removes - -In code: the loudest-bin estimator and the bin-ownership loop in `AudioBands.h` with their technical notes, and, as step 2 confirms, `levels`, `gain`, the conditioner's ratio and maximum gain and the two learned tables. In the docs: the audio DSP roadmap is gone, its prior art and adaptive gate in this plan and its source list in the backlog above; the audio-reactive follow-ups section left the light backlog and the desktop-capture and noise-floor items left the core backlog, into steps 2 and 3 or the backlog above; per-band onsets left the live-performance plan for step 4. diff --git a/docs/work/Plan-20261028 - Audio that answers the music (4 of 6).md b/docs/work/Plan-20261028 - Audio that answers the music (4 of 6).md new file mode 100644 index 000000000..192e61711 --- /dev/null +++ b/docs/work/Plan-20261028 - Audio that answers the music (4 of 6).md @@ -0,0 +1,282 @@ +# Plan: audio that answers the music + +Approved 2026-10-30 and revised 2026-11-03 ([the plan change](#the-plan-change-2026-11-03)), built in small steps judged on the bench, so the steps below follow what the music shows. The goal is the best visible answer to the music: silence is dark, a quiet passage stays quiet, a loud one is loud, the bars sit balanced across the spectrum, every band answers its own range and not its neighbor's, the bass separates note from note, a kick drum is found whatever song is playing, the beat lands on the beat, and the lights follow the harmony. The least to set follows from it, since a level that learns the song beats any knob set for one song. The analysis stays one pipeline on every board; calibration against a measured chain is not the goal and goes to the backlog. + +The yardstick is twofold. For the bands it is the real-time analyzer, whose third-octave filters a standard defines (IEC 61260-1). For what is read from them it is music information retrieval, the field whose libraries (Essentia, librosa, aubio) describe music to a machine: loudness, harmony, spectral balance, onsets per band, and tempo with beat phase, in that order. Step 1 builds the bands, steps 2 to 6 one descriptor each, each step reading what the ones before it give: harmony comes third, gated by the level, so the bass note, the note onsets and the downbeat build on it. Two things the field settles that this plan follows: a band per instrument is not a thing (instruments overlap in frequency, and separating them is a neural net on a GPU), while the drum kit does separate by range; and genre presets lose to adaptation (a floor, a gate and a gain that learn the dynamics give a quiet classical passage and a loud rock chorus the same treatment with no switch). + +**Every step lands twice.** `AudioSpectrumEffect` shows the core audio as it is, the developer's view of what the step changed, and one showcase effect shows it the way an end user picks it for a show. `BeatRipplesEffect` is the model: stones dropped on the music, readable at a glance by an audience. A signal nobody draws is not verified, so the pair is part of the step, not a follow-up. + +## The design basis + +- **One pipeline, no engine select** ([CLAUDE.md, principle 3](../../CLAUDE.md#principles)): one analysis path, the same on every chip: the filter bank, with every output derived from its bands. +- **The textbook.** A third-octave band is the power through its band-pass filter, as IEC 61260-1 defines it and every digital analyzer implements it: a multirate filter bank, octave by octave, where one octave's filters run again at half the rate for the octave below. Band power makes pink noise read flat, the spectrum real music resembles and the signal an analyzer is calibrated with, so balanced bars follow by construction. A noise gate opens fast and closes slow with hysteresis, as every studio gate does. Automatic gain is one offset that holds the loudest band at the top, with a fast attack and a slow release, as a compressor's make-up gain does. +- **Study, credit, write fresh.** MoonLight's audio path is its own implementation, from the standards and standard DSP; the people whose thinking it studies are credited by name below and in the header's `@attribution`. +- **Measured on synthesized signals** on the desktop, then judged by eye on the bench: the product owner's eyes are the measurement for a light show. + +## What exists + +- **`AudioService`** ([AudioService.h](../../src/core/services/AudioService.h)): a 512-sample block, a DC blocker, a Hann window, esp-dsp's FFT on the ESP32 and a DFT on the desktop, a frame every 23 ms at the default 22,050 Hz. +- **The bands** ([AudioBands.h](../../src/core/services/AudioBands.h)): sixteen log-spaced bands, each the loudest bin of its slice. A bin is 43 Hz wide, so below about 130 Hz each band owns one bin, a tone leaks into the next band about 6 dB down, and two bass notes a semitone apart land in the same band. The learner in `BandConditioner` corrects each band's level, which lifts the leakage with it. +- **The level path**: `floor` is a silence threshold and a window bottom at once; `levels` switches between a manual `gain` and a learned window; `BandConditioner` and `LevelConditioner` learn a floor and a peak each and apply a compressor's ratio. Three mechanisms share the one job of "show the music at the right size", from three places. +- **`OnsetDetector`**: one `onset` for a hit anywhere in the spectrum, so a kick and a snare look alike. +- **The readers**: thirteen effects read `bands[16]`, the WLED sync packet carries sixteen, and MoonLive reads `audioBand(i)` and `audioPeakHz`. + +## Prior art + +Audio-reactive lighting has a lineage (WLED-SR, WLED-MM, MoonLight), and four people's thinking is weighed here, their ideas and our analysis. + +**Frank (softhack007)**, main author of the WLED-MM audioreactive usermod, who the product owner worked alongside for years: the adaptive noise gate that step 2 builds. His concept, analyzed with his permission: a standard noise gate on the time-domain level, open fast and close slow with hysteresis, keyed to a *learned* floor so it self-calibrates to whatever source is connected, with thresholds as factors of that floor rather than absolute counts. His constraints bind step 2: the gate decides "is there sound" and leaves scaling to the gain; it reads the RMS the level path already computes, so it adds no delay; the whole chain stays under 30 ms, so every smoother is a one-pole. + +**LedFx**, the host-side effect engine whose whole purpose is audio reactivity: its mel-spaced bands and per-band asymmetric smoothing, reached independently of the WLED lineage. Mel and log coincide above 1 kHz, and step 1 takes the standard's third octaves; the asymmetric smoothing is the attack and release step 2 gives the gain. + +**Damian (DedeHai)**, WLED: the fixed-point FFT for chips without an FPU. Every MoonLight audio target has one, so the bank is float; a fixed-point bank, on his reasoning, is the lever if a C3 ever analyzes audio. + +### Troy (troyhacks) + +MoonModules: [his AudioReactive rewrite](https://github.com/troyhacks/WLED), branch `troy/hdmi-on-p4-experimental`, commit `6c4615f4` of 2026-11-03, running on the bench's Olimex ESP32-P4-PC at 192.168.1.223 and checked against a hardware analyzer. + +- **No FFT.** 31 ISO 266 bands from two filter banks: the bottom 8 (20 to 100 Hz) on the input decimated by 16 to 3 kHz, behind a 4th-order Butterworth anti-alias filter, and the top 23 at the full 48 kHz. Each band is a 4th-order Butterworth band-pass, two second-order sections, solved per band so its equivalent noise bandwidth is 0.85 of the nominal width. +- **Measured on his design:** the leakage into the neighboring band is −12.2 dB at the bottom and −7.8 dB at the top; the two banks cost 0.12 and 0.99 ms per 10.7 ms frame on the P4, about 2.1 ms of analysis per frame in all. +- **The display:** sixteen bars as a subset of the 31 picked by a pattern that shifts them −3 to +3 bands, one-pole smoothing at 8 ms attack and 60 ms release, a dB window auto-ranged to the loudest band. +- **A tempo tracker** (`ar_tempo.h`): onsets from the 40 to 160 Hz energy of the 3 kHz stream, a phase-locked comb that scores each candidate period by how tightly the onsets cluster in phase, a PLL grid and a weak prior at 125 BPM; median hit rate 0.817 on a hundred house tracks. Prior art for step 5. + +Two decisions carry over as the plan's own: + +| Decision | What it does | Why it matters here | +|---|---|---| +| **A unit contract** | Every band is the shaped power through its filter, so a tone at a band's center reads exactly its own power and pink noise reads flat | A test asserts "balanced bars" and "separated bands" instead of a learner correcting for the estimator | +| **Four quantities, kept apart** | The level is the RMS of the fresh audio in dB; the floor snaps down at once and creeps up with a 10 s time constant, only while the level sits within 3 dB of it; the gate opens at `squelch` dB above the floor and shuts 4 dB lower; the AGC is one dB offset holding the loudest band at 0 dB, 20 ms attack, 1,500 ms release, frozen while the gate is shut | Nothing reads its own output, so the deadlocks of one number doing four jobs are impossible; our three mechanisms approximate this from three places | + +### Anjin's measurements, and the trackers they test against + +Anjin, on the MoonModules Discord (2026-11-03), ran a faithful port of Troy's tracker and his own filter-bank front end through labelled sets, against Essentia, the QM beat tracker, Beat This!, madmom's TempoDetector and TCN: + +- **Troy's tracker:** 97% within 2% of the label on house, level with the best offline methods; about 70% on mixed EDM and 47% on short loops of eight genres. The 125 BPM prior holds it near 125, and the comb's chance score rises with tempo, so noise locks at about 130, as .223 showed: 127 to 128 BPM from the microphone's noise floor before any music arrived. On a microcontroller nothing he tested is as small or as fast. +- **His filter-bank front end:** 8 bands with edges at 30, 100, 200, 400, 800, 1,600, 3,200, 6,400 and 16,000 Hz, one RBJ band-pass section each at the full rate, the rise in each band's level summed into a flux read 200 times a second, no FFT on the beat path: 88.4% on Beatport and 75.3% on the loops, with a fair periodicity stage. A sharper bank, he expects, gives cleaner input still, since its low bands separate the kick from the bass. +- **Agreement as confidence:** where independent trackers agreed, they were right 99 to 100% of the time, so two trackers that agree are a lock that costs almost nothing. +- **Filter delay:** a band-pass delays its band by about the inverse of its bandwidth, tens of milliseconds below 100 Hz against under one for the hats, so onsets compared across bands, a tom sweep and the downbeat need each band's delay measured with a click and subtracted. +- **What to test on:** known tempos across 40 to 160 BPM, and drum and bass in particular, at 170 to 175 BPM with a half-time feel near 87, where a 125 prior invites the octave error. His harness and data are reusable, offered for MoonLight's desktop build. +- **More from the thread (2026-11-03):** the comb's score for random onsets is 0.39 at 90 BPM and 0.58 at 175, since its ±70 ms window covers more of a short beat, and noise locks near 130 at about 0.45, so a raw score is no confidence until the comb is chance-corrected; 12 s of picked kicks is thin evidence, and a longer memory or the comb run over the continuous onset curve does better; Troy's tracker tends to fail at double the tempo and Anjin's at half, opposite directions that make them a strong pair. A reference tracker, **BpmDj** (an offline tool; not Troy's numbers), reads 89.8% within 2% on 774 Beatport previews, but drum and bass only 28%, with 55% double or half, mostly label errors (Beatport lists 116 to 119 where trackers answer 174 to 178); on 296 held-out Freesound loops Anjin's fold reads 75.3%, BpmDj 65.5%, QM 63.2%, madmom's comb 61.5%, Beat This! 57.4% and Troy's 47.0%. Anjin's Beatport figure reads 88.4% in one message and 90.6% in his table, possibly two variants, to be asked before it is cited further. The material: the [Freesound Loop Dataset](https://zenodo.org/records/3967852), with a 12 s warm-up per loop, and the [Beatport EDM Key Dataset](https://zenodo.org/records/1101082) for key. + +The textbook behind it: **Scheirer** (*Tempo and beat analysis of acoustic musical signals*, JASA 1998) is the filter-bank tracker this all descends from: a few bands, each envelope differentiated and half-wave rectified, summed, and a bank of comb resonators for the tempo. **Goto**'s real-time beat tracker found the bar boundaries from chord changes, the downbeat of step 6. **Faraldo**'s key profiles for electronic dance music beat the classical profiles on dance music in Anjin's tests, the profiles of step 3. Tempo is scored as MIREX scores it: accuracy 1 within 4% of the label, accuracy 2 also forgiving the double, half and triple. + +### Twelve to the octave: notes and harmony + +Prior art for [step 3](#steps), the same bank at twelve bands per octave, gathered 2026-11-03: + +- **Müller and Ewert's Chroma Toolbox** ([ISMIR 2011](https://archives.ismir.net/ismir2011/paper/000072.pdf), [AudioLabs Erlangen](https://www.audiolabs-erlangen.de/resources/MIR/chromatoolbox)), MATLAB and offline: 88 bands on the piano's pitches, A0 to C8, from a multirate filter bank of elliptic filters at 22,050, 4,410 and 882 Hz. The textbook precedent for the design. Six banks shifted by fractions of a semitone serve recordings not tuned to A440, which a twelve-band bank needs too, as a tuning estimate before the notes. +- **ColorChord** (Charles Lohr), [on an ESP32 with WS2812B LEDs](https://spectrum.ieee.org/amp/how-to-turn-music-into-colors-with-a-wifi-bridge-2650274517): the notes heard, folded into one octave, as LED colors. The closest prior art for notes to color on a microcontroller. +- **[The Chord Colourizer](https://arxiv.org/html/2510.10173v1)** (2025), Python and librosa: chords and key from a chromagram, averaged over 4 s chunks, shown only above a confidence score, since transients misclassify. LEDs follow. +- **[A patent](https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/5859382)** fires lighting cues on a detected chord sequence and changes the stage lighting on a detected chorus. +- **WLED's Rocktaves** maps the FFT's one peak to a note within the octave: one note, not a note spectrum. + +What is new here is the combination: one bank, live on an ESP32-P4 or S3, giving the analyzer's bars, WLED's sixteen, the notes and the harmony at once, inside a lighting system with layers, drivers and audio sync; harmony-driven effects are new in the WLED lineage. Whether it stands out is decided by the effects, not the bank: an effect that visibly does what an FFT effect cannot, such as a palette that changes exactly on the chord change. + +What a full mix allows, by the field's results: + +| Signal | Realistic | Why | +|---|---|---| +| The moment the harmony changes | yes | needs only that the twelve pitch classes shifted, not which chord; the standard harmonic-change detector is robust and cheap | +| A color from the harmony | yes | the same chord always gives the same color, and a misread gives a near color rather than a visible error | +| Major or minor, the key | mostly | needs 10 s or more of music: a slow mood color | +| The chord's name | sometimes | templates over the pitch classes get roughly 60 to 70% right on pop, neural nets roughly 80 to 85%: too often wrong to show a name | +| The bass line's note | in sparse mixes | the kick shares the range, and low notes need 0.3 to 0.6 s to separate | +| The melody, and its octave | no | every note also lights its overtones, and the octave is the classic failure of pitch detection | + +A solo instrument through line-in does much better than a full mix, and a MIDI instrument gives the notes exactly and at once. + +## Steps + +Each step ends in a desktop test, its two effects, and a bench look. The bench's songs, for the product owner and for end users, are one playlist: [MoonLight audio test songs](https://open.spotify.com/playlist/0iL47MM8XcUpJzzdKdHQD3). + +### 1. The bands by the book ✅ + +- **The bank** ([FractionalOctaveBank.h](../../src/core/services/FractionalOctaveBank.h), built 2026-11-03, `B` bands to the octave and used at three). A third-octave filter bank, multirate octave by octave: the top two octaves' band-pass filters, each three second-order sections, run at the full rate; a low-pass halves the rate, and the same three filters measure each octave below at the rate that puts it in the same place, ten octaves deep. 31 bands at 48 kHz, 20 Hz to 20 kHz, with base-2 octaves, which IEC 61260-1 allows beside base-10, so the centers sit within 2.5% of their ISO 266 labels. A band's value is the power through its filter, through a one-pole detector. +- **What derives from it.** The sixteen `bands` are picked from the 31 as Troy's default pattern picks them, so a WLED receiver sees the bars a WLED-MM sender sends. Flux and `onset` are recomputed from the bands. The dominant frequency (`peakHz`, the sync packet's major peak) is the loudest band, its position interpolated from its two neighbors, whose ratio the known filter shape turns into an offset; the FFT goes. +- **The rate (decided 2026-11-03): 24 kHz on every board.** 24 kHz carries the 28 bands from 20 Hz to 10 kHz, the 16 WLED bars among them, at half the bank's cost at 48 kHz; the three bands above 10 kHz carry cymbal sheen and the converter's own noise rather than beats, and WLED-MM's bars stop at 10 kHz too. 48 kHz adds them for an analyzer view; 22,050 Hz would lose the sixteenth bar at 10 kHz. The rate is stored by its name, 24000 sitting between 22050 and 44100. +- **`AudioSpectrumEffect`** draws 31 bars while the 31 are live, sixteen otherwise. +- **Showcase: `WaterfallEffect`**, a spectrogram scrolling down the matrix, one column per band, the newest frame on top. A sine sweep draws a clean diagonal, leakage shows as a smear beside it, two bass notes draw two lines, and a hit draws a sharp edge. +- **Desktop tests:** synthesized pink noise reads every band within 1 dB of flat, white noise rises 3 dB an octave; a sine at each band's center reads its own power within 0.5 dB and the adjacent bands at least 16 dB lower, 11.5 in the top octave where the bilinear transform squeezes the filters toward Nyquist (measured 2026-11-03: 17 to 21 dB below 10 kHz, 12 dB between the 16 and 20 kHz bands); 50 Hz and 60 Hz land in different bands; a sweep lights the bands in order and reads back as `peakHz` within a set percentage of its frequency; a synthesized kick still fires `onset` while steady pink noise does not; the bank's cost per block is recorded. +- **Bench:** a sine sweep and pink noise through the line input, side by side with .223 running Troy's bank on the same source, and the cost measured on a classic ESP32 before anything builds on it. +- **Each band's delay, measured and pinned (2026-11-03).** A click through the bank reaches each band's peak after 118 ms at 31.5 Hz, 67 at 63 Hz, 42 at 100 Hz, 19 at 250 Hz, 6 at 1 kHz and 1 ms from 6.3 kHz up, the band-pass's own delay and, below 400 Hz, the halving low-passes'; a test pins it. The halving delay stays a design criterion beside the cost: a higher corner or a halving by four per stage shortens it. +- **Measured on the boards (2026-11-03).** The bands' share of one core, on the card as `cpu`: 6.0% on the P4 at 48 kHz (470 FPS on .221), 16.3% on the S3 at 48 kHz (350 FPS, the FFT release ran 320), 12.3% on the classic ESP32 at 22,050 Hz (82 to 86 FPS on a Dig-Next-2, the October build ran 89). The bank is fed a block at a time, each octave's three bands side by side in plain C, and AudioService sits in internal RAM; fed a sample at a time it cost three to four times more, and esp-dsp's generic Xtensa biquad kernel made it slower still, so esp-dsp stays out. +- **The audio task (2026-11-03).** The read and the analysis run on a task of their own with a blocking read, as Troy's does, the frames passing to the render tick through a single-producer single-consumer ring; a board without tasks analyzes in the tick. Read in the render tick, a slow frame lost samples: the P4 delivered 47,139 a second for 48,000 and the classic ESP32 about 44,600, measured as the input's real rate on the card. On the task the P4 delivers 48,048 at 500 to 545 FPS. Its priority is 6, over the frame encoder's 5: a lost sample is lost for good while a late frame is only late, and below the encoder a busy core starved it, the Waveshare's 64 by 64 panel to a third of its samples and the classic at 48 kHz to 39,000. At 24 kHz the Waveshare delivers 24,066 at 148 to 155 FPS with the bands at 7.5% of a core. The input's DMA ring holds 60 ms at any rate. +- **Built (2026-11-03):** the bank and its tests, AudioService on it with the FFT and its platform seam gone, the 31 in `AudioFrame` and conditioned like the sixteen, one 10 ms detector for every band, `AudioSpectrumEffect` at 31 or sixteen bars, `WaterfallEffect`, and the `cpu` readout; on the desktop, the P4, the S3 and the classic ESP32. +### 2. One level path, no knobs ✅ + +- **Built (2026-11-04), in [AudioDynamics.h](../../src/core/services/AudioDynamics.h), pure maths beside the bank:** the **level**, each block's RMS in dBFS; the **floor**, the quietest block of the last 10 to 20 s, minimum statistics (Martin 2001), so it follows a room growing noisier by any step and forgets a dip, as the Waveshare's mic start and the pre-commit review showed the first design, creeping only within 3 dB, could not; the bands' window stops at a floor of their own, the quietest loudest band, since a band's power sits under the RMS; the **gate**, opening `squelch` dB over the floor and closing 4 dB lower (Frank's adaptive gate, under his constraints above), after 250 ms once the music has left the window, as stopped music on line-in does, else after 3 s, since a song without a pause lifts the floor into its quiet moments and a soft passage dips near it (.221 on Satie, 2026-11-04; holding the floor down instead opened the gate on the line's silence); the **top**, following the loudest band with a 20 ms attack and a 3 s release, only while the level is over the close threshold, so a pause leaves it where the music had it. The bands map through the 30 dB window under the top, Troy's `RtaRange` and a hardware analyzer's scale range (40 dB until 2026-11-04, when his settings showed the contrast a narrower window gives), and the level through a top of its own. The window's bottom never sinks under the floor: near the floor the window narrows rather than the top rising, so a quiet passage is lifted only as far as the room's noise allows. That bound answers the lift cap the design left open. +- **Removed:** `BandConditioner`, `LevelConditioner`, the `levels` and `gain` controls, the conditioner's ratio and maximum gain, and the two learned tables. `floor` is renamed `squelch`, as WLED-MM and radios name it; [MIGRATING](../reference/MIGRATING.md) carries both. +- **Desktop tests:** silence keeps the gate shut and the bars dark; music opens it; music shorter than the window leaves the floor alone; the floor follows a 10 dB step and forgets a dip; the bands' own floor keeps a scale for quiet music; the gate's hysteresis and hold; a quiet song after a loud one reaches the top; music near the floor narrows the window, the noise staying dark; the top holds still while gated; the gate's place on the bands' scale. +- The card's `dynamics` line shows the level, the floor, the top and the gate, so a gated room reads as gated rather than as a dead audio path. +- **`AudioSpectrumEffect`** draws the gate as a mark at its right edge, white while open and red while gated, and the dominant frequency as a mark along its top, each a bar wide, behind its one `readouts` switch with the level meter; the floor is the bars' base by construction. Every coloring follows the selected palette, so a palette following the music reaches the spectrum too. +- **Measured on the boards (2026-11-04)**, this step's build, AudioSpectrum on live audio, each board at its own rate and then at 48 kHz; the bands' share of one core is the card's `cpu`: + + | Board | Lights | FPS | Largest cost in a tick | Bands at its rate | At 48 kHz | + |--|--|--|--|--|--| + | P4, .221 | 16,200 on HDMI | 369 | the effect, 1.6 ms | 3.6% at 24 kHz | 6.8%, 310 FPS | + | S3 Waveshare, .127 | 4,096 on HUB75 | 153 | the Hub75 driver, 6.2 ms | 7.2% at 24 kHz | 14.4%, 135 FPS | + | Classic Dig-Next-2, .122 | 256 WS2812 | 90 | the RMT driver, 9.3 ms, the wire taking 7.7 | 8.4% at 22,050 Hz | 19.0%, 82 FPS | + + The cost follows the rate: every octave's filters run at the rate that octave needs, so the work per input sample is the same at any rate, about 33 sections, and half the rate is half the work. That is 15 to 30 cycles a section across the three cores, plain C. Open: the input's measured rate wanders, 20,700 to 22,300 Hz on the classic and 23,500 to 24,700 on the S3; at 48 kHz the P4 loses a fifth of its frames for 3% more of a core, the audio task waking the render core twice as often being a hypothesis; the Hub75 driver's 6.2 ms is some 360 cycles a pixel. +- **No showcase effect (2026-11-04):** an audio modifier was dropped as adding no value; a MoonLive palette following `audioSmooth()` already reaches every palette effect. +- **Bench (2026-11-04):** the floor and the gate read right on the Waveshare and the P4; the product owner closed the rest of the bench. + +### 3. The lights follow the harmony ✅ + +- **The bank at twelve bands per octave**, `FractionalOctaveBank<12>` counted from A440, on the chips that carry it: one band per semitone, 20 Hz to 20 kHz, and the 31 third octaves as sums of four. A tuning estimate comes first, since a recording off A440 smears each note across two bands; Müller's tuning-shifted banks are the prior art. +- **What derives from it:** the twelve pitch classes (chroma) by folding the octaves, a harmonic-change signal for the moment the harmony moves, and the key with its major or minor over 10 s or more, matched against Faraldo's profiles for electronic dance music beside the classical ones. The robust signals only, by [what a full mix allows](#twelve-to-the-octave-notes-and-harmony): no chord names, no melody. +- **One bank per board, decided here by measurement.** Four layouts compared on fast response, CPU and harmony: the three-band bank alone; the twelve-band bank with the third octaves as sums of four semitones, whose bass bands respond about four times slower (step 1 measured 67 ms at 63 Hz for a third octave, so some 270 ms for semitones; Anjin estimates about 100 ms a section near 55 Hz) since a semitone filter is that much narrower; third-octave filters below about 200 Hz and semitones above; and both banks side by side. Desktop: a synthesized kick, a 60 Hz burst with its click, timing the bass bands' rise and the onset in each layout, and each layout's cost per sample. Board: the cost on a classic ESP32 and on a P4. Bench: a kick track on the waterfall, the layouts side by side, judged by eye. The fastest layout that holds the response and fits the board's budget wins, per board type. A board without twelve to the octave has no harmony of its own and reads it through audio sync from one that has. +- **Decided by measurement (2026-11-04): the third octaves as they are, beside a semitone bank limited to 2.5 kHz, on every board.** Desktop, 24 kHz, the click's peak in the 63 Hz band and the cost against the third octaves alone: + + | Layout | Cost | 63 Hz | Harmony | + |--|--|--|--| + | the third octaves alone | 1.0× | 67 ms | none | + | semitones alone, the thirds as sums of four | 2.55× | 187 ms | full | + | thirds below 200 Hz, semitones above | about 2.5× | 67 ms, the mids 3× slower | no bass notes | + | both banks, full range | 3.55× | 67 ms | full | + | **the thirds and the semitones to 2.5 kHz** | **2.1×** | **67 ms, every bar as before** | **85 notes, 19 Hz to D#7** | + + Harmony needs nothing above 2.5 kHz, and the bank's cost sits in its top octaves, so the limited bank starts a halving down; a quarter of the rate is out of reach, the halving low-pass passing only to 0.24 of the halved rate. 2.07× at 22,050 Hz, 1.73× at 48 kHz; on the boards, scaled from step 2's measurement, about 15% of an S3 core, 17.5% of a classic's and 7.6% of a P4's, to be measured. The semitone bands answer as slowly as alone, 115 ms at 110 Hz and 34 at 440, which a chord's pace allows; the bars and onsets keep the fast bank. A `harmony` switch, on by default, turns the semitone bank off where nothing reads it: it saves the CPU and, once [the release](#backlog) lands, the memory; the frame's harmony fields add 99 bytes to each of its ten copies. +- **Built (2026-11-04), parts 1 to 3:** `FractionalOctaveBank` takes a band limit, halving while its top band fits where a lower octave sits; `SemitoneBank` from A440 to 2.5 kHz runs beside the 31 in AudioService. [AudioHarmony.h](../../src/core/services/AudioHarmony.h) folds the notes from C2 up into the twelve pitch classes, each an amplitude against the loudest over 200 ms, and finds the harmonic change by Harte, Sandler and Gasser (2006): the twelve as a point on the tonnetz's circles of fifths, minor and major thirds, a change being that point moving fast against itself 100 ms behind. A held chord moves it under 0.02, noise included, C major to A minor 0.13, C, G, A minor and F 0.24 to 0.27; a change fires at 0.06 and re-arms under 0.03, none in the 500 ms after the gate opens. `AudioFrame` carries `chroma[12]`, `harmonyChange` and the piano's keys A0 to D#7 as `notes[79]`; the card's `notes` line names the three strongest classes and the changes a second; `AudioSpectrumEffect`'s `bands` gains `notes`, one bar a key. Desktop tests: a C major triad lights C, E and G; a note reads its class in any octave; C major to A minor fires one change within 300 ms, a held chord none, C, G, A minor and F three; a shut gate forgets the harmony and reopening fires none; A4 lights its own key; `harmony` off empties the notes and on brings them back. +- **The gate holds the harmony.** The twelve pitch classes are normalized by step 2's level and gate, so a silent room shows no harmony made of its noise. +- **`AudioSpectrumEffect`** shows the twelve pitch classes as a ring or a row, and marks each harmonic change. +- **Built (2026-11-04), part 6:** with `readouts` and `harmony` on, `AudioSpectrumEffect` draws the twelve pitch classes as a row over the bars, C at the left, each in its palette color as bright as it sounds, the row going dark for 100 ms on each harmonic change (a white flash read too heavy); the bars, the peak mark and the note names sit under it. `noteNames` writes the three strongest classes at the top left, on its own switch. +- **Built (2026-11-04), part 7:** [harmony.mlp](../../moonlive/palettes/harmony.mlp), a MoonLive palette on two new builtins, `audioChroma(i)` and `audioChordChange()`: each pitch class a fixed hue on the circle of fifths, so C, G, F and A minor take neighboring colors; on each chord change the three strongest classes, ordered by their place on the circle, set the sixteen entries in three hues, crossfading over `crossfade` (150 ms); the chord already showing changes nothing, so frames faster than the audio and a returning chord leave it; before the first chord the whole circle. The frame hand-over carries a dropped block's change as it carries its onset. The StadBeest autopilot's fire palette moves to 66, the new palette sorting before it. +- **Built (2026-11-04), parts 4 and 5:** the **key** by Krumhansl-Schmuckler key finding, the twelve averaged over 15 s against two profile pairs at every tonic, Krumhansl and Kessler's and Faraldo's from dance music (Essentia's `edma`), each key scoring the better of its two, named after 10 s of open gate and changing only when another key correlates 0.05 better; `AudioFrame.key`, `audioKey()`, the card's `key` line and AudioSpectrum's `noteNames` show it. The **tuning** by where each strong note's power sits between its neighbors, a parabola in dB averaged on the circle over 10 s, reading three quarters of the offset; once past 10 cents for 10 s the semitone bank retunes by it, so music 40 cents sharp settles within a few cents, shown on the `key` line. Desktop tests: C, F, G read C major after 10 s and not before; A minor, D minor and E read A minor; a pause and a borrowed chord keep the key; a track shaped like Faraldo's G minor reads G minor; a tone 40 cents sharp reads sharp; music 40 cents sharp retunes the bank by 30 to 50 cents. +- **Measured on the boards (2026-11-04), `harmony` off against on:** the S3 Waveshare at 24 kHz 7.2% to 17.2% of a core, 153 to 132 FPS; the classic Dig-Next-2 at 22,050 Hz 8.2% to 19.2%, 62 to 54 FPS; the P4 3.6% to 8.1%. About 2.3 times the third octaves alone, a little over the 2.1 the host measured. +- **Showcase: a palette that changes on each chord change**, its colors from the pitch classes, so the same chord always returns as the same colors. +- **Desktop tests:** a synthesized C major triad lights C, E and G among the twelve; a step from C major to A minor fires one harmonic change and steady chords fire none; a recording tuned 20 cents sharp still lands each note on its own band after the tuning estimate. +- **Bench, by end users (2026-11-04):** marked done by the product owner for end users to check in the release, with the songs below from the test playlist. A pop song and a piano piece through line-in, the palette turning on the chord changes. The piano pieces, each for what it shows: the intro of "Let It Be" (The Beatles), C, G, A minor and F a chord every two beats, the tests' own progression, so `notes` steps through the four triads at about a change a second; Satie's "Gymnopédie No. 1", two chords alternating a bar each, every change apart and nothing firing between; Pachelbel's Canon in D on piano, eight chords repeating, the same chords returning as the same names. The 0.06 threshold is judged here, on real songs. + +### 4. The kick is found in any song ✅ + +- Three sums beside the bands, each a `uint8_t` 0 to 255 on the bands' scale: the power of the third-octave bands from 20 to 125 Hz, 160 Hz to 2 kHz, and 2.5 kHz up, so an effect keyed on the bass finds the kick whichever band it lands in. A sum of band powers is exact, as an octave is the sum of its three thirds. MoonLive gains `audioBass`, `audioMid` and `audioTreble`. +- **The bass line's note** beside the bass energy, from the semitone bands of step 3 where the board has them: in a sparse mix the bass follows its note, in a dense one the kick shares the range and the note reads only as often as it holds. +- **`AudioSpectrumEffect`** draws the three sums beside its bars. +- **Showcase: `BeatRipplesEffect`** keyed on the bass sum, stones dropped on the kick rather than on any hit. +- **Bench, by end users (2026-11-04):** marked done for end users to check in the release, with the test playlist. A kick-drum track, the ripples on the kick and not on the vocal: Daft Punk's "Around the World", a steady kick under a bass line and a repeated vocal, and Jeff Mills' "The Bells", a 909 kick under fast bells and hats. +- **Built (2026-11-04):** `bankToRanges` gives `bass`, `mid` and `treble`, each its range's power per band through the bands' window, so a range reads on the bands' scale and a bass hit over three thirds does not saturate it; `bassNote` is the loudest semitone from B0 to B3 as a MIDI number while it stands 6 dB over its range, else 0. MoonLive gains `audioBass`, `audioMid`, `audioTreble` and `audioBassNote`. `AudioSpectrumEffect` draws each range as a grey line across its own bars at its level, on the bars rather than beside them so it takes no room, and `noteNames` adds the tuning to the key, "Am +12". `BeatRipplesEffect` gains `trigger`: any hit, or the kick, a hit whose strongest range is the bass, until step 5 times an onset per range. Desktop tests: a 63 Hz, 1 kHz and 6.3 kHz tone each light their own range most; A2 alone reads 45 and none while gated; ten bass notes at once name none; the lines over their bars; on the kick trigger a treble hit drops no stone and a bass hit does. + +### 5. A kick, a snare and each tom look different ⏳ + +- An onset per range (low, mid, high) from the sums of step 4, each with the flux-against-its-mean decision `OnsetDetector` already makes; `onset` stays as the any-hit signal. The bank updates every band every frame, so a mid or treble hit is timed within a frame rather than within the transform's 23 ms block. Moved here from [the live-performance plan, step 5](Plan-20261013%20-%20Audio%20reactive%20live%20performance%20(0%20of%207).md), which keeps the drum-trigger route. +- **The onset signal from the bands' powers, at 200 readings a second.** Each band's log power, its rise kept and its fall dropped, summed over the bands every 5 ms: Scheirer's construction and Anjin's, read from the bank's detectors rather than from the sixteen display bytes once a block, which is the flux `onset` reads today. +- **Each band's delay subtracted** before onsets are compared or shown together, step 1's measured delays, so a tom fill sweeps the rig in time.- **An onset per band** beside the three ranges, the same decision on each of the 31, with a refractory time per band so a snare roll at 15 to 20 hits a second stays separate hits. The toms are pitched, from about 80 Hz for the floor tom to 400 Hz for the high one, so each lands in its own band and a tom fill reads as a sweep across the bands. +- **A new note starts** where a semitone band's onset fires on a board with step 3's bank: the attack of a piano key or a plucked string, beside the drum hits, and the toms by their pitch. +- **The kick is timed by its click.** A narrow bass band takes tens of milliseconds to rise, while the beater's click at 2 to 5 kHz rises within a few: the click's band times the hit, and the low bands confirm it was a kick and not a bass note. +- **`AudioSpectrumEffect`** flashes each range's onset above its bars, and each band's onset on its own bar. +- **Showcase: a drum-kit effect**: a kick splashes from the floor, a snare flashes the middle, a hi-hat sparkles the top, and each tom lights its own place on the rig, so a drum solo plays across it. +- **Desktop tests:** a synthesized kick fires the low onset and not the high one, a synthesized hi-hat the reverse; three synthesized toms a fourth apart fire three different bands in order; a synthesized kick with its click is timed within 5 ms of its start. +- **Bench:** a drum track and a drum solo, best through an aux send from the mixer giving the kit alone, each drum on its own layer. + +### 6. The beat lands on the beat ⏳ + +- Tempo and beat phase from the onset curve. Two trackers, run side by side: the textbook (Ellis, *Beat tracking by dynamic programming*, 2007: autocorrelation of the onset curve over 12 s or more picks the tempo in 60 to 200 BPM, and the phase that lines up with the recent onsets picks the beat), and Troy's phase-locked comb, measured on real house music, its comb run over the continuous onset curve rather than picked kicks, corrected for the score a period earns by chance and given a lock confidence, so noise no longer locks near 130. The two fail in opposite directions, Troy's at double the tempo and the textbook's to be measured, which is what makes their agreement a lock. Where the two agree the tempo is locked, the confidence an effect reads; where they disagree the frame says so. The frame carries `bpm`, `beatPhase` in 0 to 1 and `beat` for the block the phase wraps. MoonLive's `audioBeat`, a level-above-its-average guess until now, returns the tracked beat, and `audioOnset` and `audioBpm` are added. +- **Harmonic changes find the downbeat.** A beat tracker hears beats but not which is the bar's first; Troy's says so of its own. Chords mostly change on the bar line, so step 3's harmonic changes, lined up with the beat grid, place the one, and the frame carries `downbeat` and the beat in the bar. A board without harmony counts the bar from the lock, as Troy's does. +- The beat phase is what the live-performance plan's `MidiFrame` takes from a MIDI clock when one runs; the audio estimate fills the same field when none does, so an effect reads one phase from either source. +- **Tap tempo, the escape route (robwomp, 2026-11-04).** A third beat source beside the MIDI clock and the tracker, as lighting consoles, DJ mixers and pedals have it: the tempo is the mean of the last four to eight intervals between taps, a gap over about 2 s starts a new count, and the last tap sets the phase. The order is MIDI clock, then tap, then the tracker; a tap also re-phases a tracker whose tempo is right and whose beat is not. A button on the card, a MIDI pad or a GPIO through input mapping; four taps average the WiFi's 5 to 20 ms jitter well inside ±20 ms. +- **Beat-synchronous analysis once the beat locks (Anjin, 2026-11-04).** Each feature averaged over a beat rather than a block (Bello and Pickens 2005; Ellis 2007), time-synchronous averaging in vibration analysis: step 3's pitch classes per beat, their change checked on the beat boundaries where chords change, so fewer false changes and each on the beat; step 5's band onsets folded at the beat period, so hats and rides gather at their places in the sixteenth grid and random noise spreads. It sharpens timing, not the spectrum, and needs a tempo within about 1%, a 2% error smearing the fold within a few bars; Troy's bass-led tracker guides it. The bank suits it, every band updating every block, so a beat boundary falls anywhere. +- **`AudioSpectrumEffect`** shows the tempo and a marker on each beat. +- **Showcase: `BeatRipplesEffect`** on `beat` instead of `onset`, the ripples on the pulse rather than on every hit, a **beat sweep**, a bar crossing the rig once per beat, its position from the phase, and a **palette per bar** turning on the downbeat. +- **Desktop tests:** a synthesized click track at 120 BPM reads 120 within 1 BPM and `beat` fires within a block of each click; a track that steps to 140 BPM follows within four beats; silence reads no tempo; a synthesized progression changing chord every four beats puts `downbeat` on the change. +- **Corpus tests:** Anjin's labelled sets and harness through the desktop build, the Freesound loops with a 12 s warm-up each, known tempos across 40 to 190 BPM, scored as MIREX does (accuracy 1 within 4%, accuracy 2 forgiving the double, half and triple) and reported per genre, with 3:2 as its own class rather than "wrong"; beside Troy's tracker's 97% on house, about 70% on mixed EDM and 47% on loops, and BpmDj's table. +- **Chance and silence tests:** random onsets at 90 and 175 BPM lock at neither, after the chance correction; beatless music (ambient, implied beats) reads "no lock" rather than a tempo. +- **Bench material:** drum and bass, hard techno with a 909 kick whose fast click must not read as a hat, Jeff Mills' unquantized swing, breakcore and sliced amen breaks, and a jam band for the non-dance end. + +## What an effect reads + +[`AudioFrame`](../../src/core/util/AudioFrame.h) is the whole contract: one flat struct per tick, every field a small integer, read through `AudioService::latestFrame()` by an effect and through builtins by a MoonLive script. Today it carries the level (raw and smoothed), the sixteen bands (raw and with meter ballistics), the dominant frequency with its magnitude, the flux and `onset`. The plan widens the struct and nothing else: + +| Step | New fields | MoonLive | +|---|---|---| +| 1 | the 31 third-octave bands, and whether they are live; `bands` and `level` mean what they did, measured better | a read of the 31 | +| 2 | none; `level` read better | | +| 3 | the twelve pitch classes, `harmonyChange`, the key and its mode, the tuning, the piano's keys | `audioChroma(i)`, `audioChordChange`, `audioKey` | +| 4 | `bass`, `mid`, `treble`, and the bass note | `audioBass`, `audioMid`, `audioTreble`, `audioBassNote` | +| 5 | `onsetLow`, `onsetMid`, `onsetHigh`, an onset per band, and a new note | `audioOnset(range)`, `audioBandOnset(i)`, `audioNoteOnset` | +| 6 | `bpm`, `beatPhase`, `beat`, `downbeat` and the beat in the bar | `audioBpm`, `audioBeat`, `audioDownbeat` | + +A field is 0 when its source is absent, so an effect on a board without a microphone draws its idle state, as today. The new fields are local: the WLED audio-sync packet carries the sixteen and none of the rest, so a board in receive mode leaves them at 0, `AudioSpectrumEffect` falls back to sixteen bars there, and a desktop test pins both. + +## What it costs, per chip + +**Analysis is not where the frame goes.** AudioService's fixed I2S block read adds 13 to 22 µs to an average tick ([performance.md](../reference/performance.md), 2026-06-17). Each step keeps it that way, and its desktop test and bench run record the tick it adds. + +| Step | What it adds | Estimate, to be measured | +|---|---|---| +| 1 | the bank: the full rate carries two octaves and every octave below halves the samples, so about 33 second-order sections per input sample with the halving low-passes; the 512-point FFT, its window and its 4 KB go | **measured: 6.0% of a P4 core at 48 kHz, 16.3% of an S3's, 12.3% of a classic ESP32's at 22,050 Hz**, read on the card's `cpu` | +| 2 | a few multiplies and two exponentials for the floor, gate and top | negligible | +| 3 | the bank at twelve to the octave, per the layout the step chooses, plus the folding and the change detector per frame | the twelve-band bank about four times step 1's; measured beside it on the classic ESP32 and the P4 | +| 4 | three sums over 31 values, and the loudest bass semitone | negligible | +| 5 | three flux decisions, and one per band | negligible: a comparison a band a frame | +| 6 | an autocorrelation or comb over 12 s or more of the onset curve, a phase fit, and the harmonic changes lined up with the grid | about 16,000 multiply-adds per block, well under a millisecond on a classic ESP32 | + +**Each chip measures what it can carry, and audio sync shares it.** Every chip that analyzes audio carries the three-band signals, so those behave alike on each; the harmony runs where step 3 finds the twelve-band bank fits (decided 2026-11-03: differences between boards are accepted). A chip with spare cycles spends them on resolution: 48 kHz for the top three bands, three sections per band rather than two, twelve bands to the octave rather than three. Each is chosen per chip by the platform, a default rather than a user setting, so it adds no knob. A board that measures less reads more through audio sync: the packet says how many bands to the octave it carries, and a receiver sums finer bands into the coarser ones its effects read. + +**The classic ESP32 is the floor.** Step 1 is measured there before anything builds on it. A bank that does not fit the render's headroom there runs at 32 kHz on that chip (29 bands, all sixteen) or on the second core, before it loses a section per band. + +## The showcase per step + +| Step | `AudioSpectrumEffect` shows | Showcase effect | +|---|---|---| +| 1 | 31 bars while live, sixteen otherwise | `WaterfallEffect`: the spectrogram scrolling down the matrix | +| 2 | the gate across the bars, the floor as their base | none: a MoonLive palette on `audioSmooth()` reaches every palette effect | +| 3 | the twelve pitch classes and each harmonic change | a palette that changes on each chord change | +| 4 | the bass, mid and treble sums, and the bass note | `BeatRipplesEffect` on the bass | +| 5 | each range's and each band's onset | a drum kit: kick, snare and hi-hat a sprite each, each tom its own place | +| 6 | the tempo, a marker per beat, and the downbeat | `BeatRipplesEffect` on the beat, a beat sweep, and a palette per bar | + +More effects on the same signals, each a small change once its field exists: **a harmony color**, the rig tinted by the twelve pitch classes, from step 3; **three zones** (bass on the floor, mids between, treble at the top, breathing with their range) from step 4; **`PulseEffect` and `PaintBrushEffect` on the beat**, one shell or stroke per beat, from step 6. + +## Backlog + +On the topic and not a step. What remains here when the plan ships returns to the Project as cards, item by item, then. + +- **A sync packet for every band count.** WLED receivers accept only the 44-byte `00002` packet and drop anything over 96 bytes, so the sixteen stay in it and the bands travel in a second packet type under its own header, which WLED ignores. It describes itself: bands to the octave, the reference frequency, the first band and the count, then the values (about 45 bytes for 31 bands, 135 for 121). A receiver sums finer bands into the coarser ones its effects read; a coarser packet cannot give finer bands, so an effect that needs them idles. MoonLight decides the format (2026-11-03). +- **Troy's display settings, for a like-for-like comparison.** The pattern that shifts the sixteen −3 to +3 bands, the dB window span, auto or fixed range, the dB reference, attack and release. A run pins each on both boards. +- **Calibration**, what a rig cannot show, taken when a user or an effect asks: a biquad pre-filter chain (rumble high-pass, anti-alias low-pass) from esp-dsp's `dsps_biquad_f32`; calibration against a measured chain and a self-test on the card. Troy's rewrite has both, checked against a hardware analyzer. +- **More audio effects on the bands**, 2D and palette-driven frequency-reactive ones, beside [the showcases](#the-showcase-per-step). +- **Pin auto-scan**: detect the microphone's `sdPin` with `wsPin` and `sckPin` fixed, a noise prompt and a confirm; explicit pin controls ship today. +- **Sources beyond the I²S microphone**, each a variant behind the same platform read, the analysis untouched. The I²S peripheral already drives MCLK (`mclkPin`) for a line-in ADC, and `codecGain` sets an ES8311 or ES7210 between microphone and line level. + - **PDM microphones**: the IDF `i2s_pdm` driver, a sub-mode of the same peripheral. + - **Analog line-in**: DedeHai has it on the S3 and Troy in ParrotRadio, where he recorded and played back through it. An analog path is validated by listening to it, since one that only feeds a level meter "may not be as accurate as it looks" (Troy). + - **Multi-channel front-ends**: a TDM codec (the ES7210 on the Waveshare RGB-Matrix board) or a DSP board giving one analyzed channel per instrument, the input [the live-performance plan](Plan-20261013%20-%20Audio%20reactive%20live%20performance%20(0%20of%207).md) needs for acoustic drums. +- **Release the analysis outside local mode (next commit, 2026-11-04).** The two banks, the sample block and the harmony state are fixed members of AudioService, about 13 KB of internal RAM held in receive and simulate mode, and the semitone bank's 7 KB with `harmony` off, which only saves its CPU. The analysis state becomes one object allocated when the module prepares for local mode and freed when it leaves, the semitone bank and the harmony state a second one taken only while `harmony` is on, so receive and simulate hold none of it and a mode switch allocates or frees on the next prepare. Desktop tests: each mode's allocation, and a live switch both ways. +- **An instrument tuner (2026-11-04).** The semitone bands say which note sounds, not how far off it is, and a tuner needs 1 to 2 cents, a hundredth of a semitone. The bank picks the note; a period detector on the waveform itself, YIN (de Cheveigné and Kawahara 2002) or McLeod's normalized square difference (2005), the textbook pitch detectors, measures it to a tenth of a cent, for one instrument through line-in, never a full mix. The note's power against its two neighbors, as `peakHz` reads the third octaves, gives a few cents at best: enough for flat or sharp. Shown on AudioSpectrum's `noteNames` line as the note and its cents, and readable by an effect, a strip lit green when in tune. Not step 3's tuning estimate, which measures how far a recording sits from A440 over many notes. +- **Desktop audio capturing what the machine plays (2026-09-29).** `platform_desktop_audio.cpp` enumerates capture devices only (`ma_context_get_devices` with null playback lists) and opens `ma_device_type_capture`, so on a Windows bench the picker offers `default` and the microphone and the speakers are absent, with no Stereo Mix to fall back on. miniaudio has `ma_device_type_loopback`, WASAPI-only, taking a playback device: enumerate playback devices too, mark them in the picker so a microphone and "what is playing" tell apart, and open loopback when one is chosen. macOS has no equivalent and needs a virtual device such as BlackHole, so the picker offers what the platform can do rather than a row that fails. A disconnected microphone jack reports a plausible level (RMS 20 to 30 at mains hum), which the status of step 2 tells from a working input. + +## Open questions + +- **Which settings stay on the card:** step 2 settles it per setting on the bench. **Recommended (2026-10-28):** the result decides, not the count; the expectation is `floor` alone, and a response-speed setting (attack and release) is the likeliest second if a bench case wins with it. +- **Whether step 2 keeps a manual mode** for a show that wants deterministic levels. **Recommended (2026-10-28):** no; freezing the floor and the top is the deterministic mode, as a `freeze` toggle, if a show asks. +- **The classic ESP32's default rate: settled (2026-11-03).** At 48 kHz its core 1 cannot carry the bank beside the LED encoder, so every board runs 24 kHz, the rate above. +- **Where the bank runs: settled (2026-11-03).** On an audio task of its own, above. + +## What it removes + +In code: the loudest-bin estimator, the band-edge and bin-ownership code in `AudioBands.h` with their technical notes, and the FFT with its window, the platform's `audioFft` seam on both platforms and its test (decided 2026-11-03: the readers of `peakHz` map it to a hue or a position on a log scale, which the interpolated band gives at a fraction of the cost; whether esp-dsp stays, for its assembly biquad kernels, is step 1's measurement on the classic ESP32); removed in step 2, `levels`, `gain`, the conditioner's ratio and maximum gain and the two learned tables. In the docs: the backlog's decimated FFT and filter-bank trial, settled by step 1; earlier, the audio DSP roadmap, the audio-reactive follow-ups and the desktop-capture and noise-floor items moved into this plan, and per-band onsets left the live-performance plan for step 5. + +## The plan change (2026-11-03) + +**What changed.** The plan grew a sixth step: the lights follow the harmony, from the same bank at twelve bands per octave, as step 3, right after the level path that gates it, so the bass note, the note onsets and the downbeat of the later steps build on it. Which bank each board runs is step 3's measurement, fast response weighed with CPU and harmony, and boards may differ in what they measure, audio sync sharing it. Step 1 was "balanced bars": each band the power summed over its slice of the FFT, the sixteen bands kept. It is now "the bands by the book": a multirate third-octave filter bank measuring the 31 ISO bands, the sixteen picked from them, the dominant frequency interpolated from the bands, and the FFT gone. Every step now lands in `AudioSpectrumEffect` and in one showcase effect. The backlog's decimated FFT and filter-bank trial are settled by it, and the default rate rises to 48 kHz. + +**Why.** The bench put the two engines side by side on the same line input: Troy's filter banks on .223, MoonLight's FFT on .221. The FFT's 43 Hz bins cannot separate the bass, whatever the bands are summed from: a third-octave band at 20 Hz is 4.6 Hz wide, and below about 400 Hz a band is narrower than two bins. Fixing that inside the transform takes several FFTs at falling rates, a filter bank built the hard way. For third-octave bands the standard's own construction is the filter bank, and the octave-by-octave form costs about twice its top octave, about half of Troy's two banks. + +**Pros.** + +- The bass separates, down to 20 Hz, each band on its own filter. +- Every band updates every frame: a mid or treble hit is timed within a frame, not within a 23 ms block, which the live-performance plan's latency asks for and steps 5 and 6 build on. +- Pink noise reads flat by construction, so balanced bars need no learner correcting the estimator. +- One measurement serves every resolution: 31 bars, the sixteen, ten octaves as sums of three, and bass, mid and treble as sums of ranges. +- The bars compare with a hardware analyzer and with Troy's WLED bar for bar. +- The cost stays near Troy's two banks while each band gets a third filter section, for 17 to 21 dB of separation where two sections give 12. + +**Cons.** + +- **Cost per sample, not per block:** about 1.6 million filter sections a second at 48 kHz: 6% of a P4 core, 16% of an S3's, and 12% of a classic ESP32's at 22,050 Hz, where the FFT cost a few percent. A C3 without an FPU cannot carry it. +- **Delay grows toward the bass:** the band-passes and the halving low-passes delay the low bands by tens of milliseconds, 118 ms at 31.5 Hz against 1 ms in the treble, so timing across bands needs each band's delay subtracted. +- **Separation is a filter's, not a brick wall's:** two sections per band leak −7.8 dB into the next band at the top in Troy's design; three sections improve it at 50% more cost per band. +- **The lowest bands jitter and react slowly.** Telling 20 Hz from 25 Hz takes about 0.2 s of signal whatever the method, and a detector at 20 Hz holds less than one cycle, so it needs smoothing. +- **The dominant frequency is coarser in the treble:** interpolated within a band 2 kHz wide at 10 kHz, where the FFT's bins are 43 Hz; finer in the bass, where the bands are narrower than a bin. Its readers map it to a hue or a position on a log scale. +- **Design work the FFT does not need:** the filters per rate, the halving low-passes, and float precision at the lowest bands. +- **A higher default rate:** 48 kHz doubles the samples read per second against 22,050 Hz. diff --git a/docs/work/backlog_mirror/cards.json b/docs/work/backlog_mirror/cards.json index 610acb654..e1dea3716 100644 --- a/docs/work/backlog_mirror/cards.json +++ b/docs/work/backlog_mirror/cards.json @@ -940,7 +940,7 @@ "number": null }, { - "title": "E1.31 multicast never arrives (2026-10-30)", + "title": "E1.31 multicast never arrives: Network Receive joins no group", "area": "Effects", "module": "", "kind": "Bug", @@ -2029,6 +2029,16 @@ "card": "https://github.com/users/MoonModules/projects/5?pane=issue&itemId=287087406", "number": null }, + { + "title": "A Pi as the room's audio source: stream in, analyze, sync out (2026-11-03)", + "area": "Services", + "module": "AudioService", + "kind": "Feature", + "status": "Backlog", + "process": "", + "card": "https://github.com/users/MoonModules/projects/5?pane=issue&itemId=291637725", + "number": null + }, { "title": "A Service that calls another device's API (robwomp, 2026-10-11)", "area": "Services", diff --git a/docs/work/backlog_mirror/effects.md b/docs/work/backlog_mirror/effects.md index 3be6cb0b3..c5e438999 100644 --- a/docs/work/backlog_mirror/effects.md +++ b/docs/work/backlog_mirror/effects.md @@ -193,7 +193,7 @@ Kind: Bug · [Card](https://github.com/users/MoonModules/projects/5?pane=issue&i **Why it waits.** It is fourteen effects' worth of change across audio-reactive and simulation families, each needing its own judgement about whether to clear, fade, or seed differently — not a mechanical sweep. `unit_Effects_gridsweep.cpp` already measures it (`afterFirst`) and asserts only the settled frame, so the number is visible without blocking. -### E1.31 multicast never arrives (2026-10-30) +### E1.31 multicast never arrives: Network Receive joins no group Kind: Bug · Status: Next · Issue: [#216](https://github.com/MoonModules/MoonLight/issues/216) · [Card](https://github.com/users/MoonModules/projects/5?pane=issue&itemId=288372206) diff --git a/docs/work/backlog_mirror/services.md b/docs/work/backlog_mirror/services.md index 43ef3913a..38b60bdd5 100644 --- a/docs/work/backlog_mirror/services.md +++ b/docs/work/backlog_mirror/services.md @@ -2,6 +2,19 @@ Generated from [the Project](https://github.com/users/MoonModules/projects/5) by `moondeck/report/project_mirror.py`: edit the cards, not this file. +## AudioService + +### A Pi as the room's audio source: stream in, analyze, sync out (2026-11-03) + +Kind: Feature · Platform: Pi · Stage: Test · [Card](https://github.com/users/MoonModules/projects/5?pane=issue&itemId=291637725) + +A Pi with MoonLight can be the room's digital audio source with what already exists.
