# @suaveplan/react-audio - React surface for the Suaveplan audio family — Phase 2 + Phase 2b (extras) + Phase 3 shipped. Provides provider + hooks + stores + error codes + a11y helpers + Phase-2 primitives (PluginSlot, PluginChainView, PresetManager, knob/slider) + composed-plugin UIs (TransportControls, TrackList/TrackRow, MasterMeter, Mixer, AudioVisualizer, AudioPlayer/BasicPlayer/PremiumPlayer, MicrophoneControls, GLaDOSControls, PluginLoader) + Phase 3 MIDI learn-mode (`<MidiControllerSetup>` + `useMidiController`).
|
||||
|
||||
React surface for the Suaveplan audio family. **Phase 1 of 3 —
|
||||
foundation** (provider + hooks + stores + error codes + a11y helpers).
|
||||
Components ship in Phase 2 (`enterprise-react-audio-components`);
|
||||
the MIDI learn-mode panel ships in Phase 3
|
||||
(`enterprise-react-audio-midi`).

|
||||
|
||||
## Install
|
||||
|
||||
```bash
|
||||
bun add @suaveplan/react-audio
|
||||
```
|
||||
|
||||
Peer deps: `react@^19`, `react-dom@^19`.
|
||||
|
||||
## Quick start
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, useTransport } from "@suaveplan/react-audio";
|
||||
|
||||
function PlayButton() {
|
||||
const { play, stop, transport } = useTransport();
|
||||
return (
|
||||
<button type="button" onClick={() => (transport.state === "playing" ? stop() : play())}>
|
||||
{transport.state === "playing" ? "Stop" : "Play"}
|
||||
</button>
|
||||
);
|
||||
}
|
||||
|
||||
export default function App() {
|
||||
return (
|
||||
<AudioProvider options={{ adapter: { sampleRate: 48000 } }}>
|
||||
<PlayButton />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## What ships in Phase 1
|
||||
|
||||
### Provider
|
||||
|
||||
- `<AudioProvider>` — owns one `BrowserTimelineAdapter`, one
|
||||
`TimelineEngine`, one `Transport`, one `ProviderBusRegistry`, one
|
||||
`ChainMap`, and one `PluginRegistry`. Strict-mode safe; disposes
|
||||
cleanly on unmount.
|
||||
|
||||
### 13 hooks
|
||||
|
||||
| Hook | Returns |
|
||||
|------|---------|
|
||||
| `useEngineState()` | `'pending' \| 'ready' \| 'error'` |
|
||||
| `useAudioEngine()` | full `ProviderState` bundle |
|
||||
| `useTimeline()` | `TimelineEngine` |
|
||||
| `useTransport()` | `{ transport, play, pause, stop, seek, setTempo }` |
|
||||
| `useTransportTime()` | current seconds, sampled at frame rate |
|
||||
| `useTrack(trackId)` | `{ track, update, remove }` |
|
||||
| `usePluginChain(trackId)` | chain composition + events |
|
||||
| `useChainPlugin(trackId, slot)` | plugin at slot |
|
||||
| `useAudioFxPlugin(pluginType)` | new plugin from the registry |
|
||||
| `useParameter(plugin, paramId)` | value + set + curve + scheduleAt |
|
||||
| `usePreset(plugin)` | plugin-level preset get/apply/save/load |
|
||||
| `useChainSnapshot(chain)` | chain-level snapshot get/restore/save/load |
|
||||
| `useBus(name)` | sidechain bus by name |
|
||||
|
||||
### Stores
|
||||
|
||||
- `useAudioStore` — UI override store (no engine state mirrored).
|
||||
- `useUiStore` — panel/theme/visualization/selectedTrack/dragState.
|
||||
|
||||
### Accessibility helpers
|
||||
|
||||
- `PARAMETER_KEY_BINDINGS` + `matchKeyBinding(event)` — central
|
||||
keymap consumed by Phase-2 components.
|
||||
- `formatAriaValueText(value, unit, min, max, options?)` — unit-aware
|
||||
`aria-valuetext` formatter.
|
||||
|
||||
### Error codes
|
||||
|
||||
All errors are `ReactAudioError extends SuaveplanError`. Codes:
|
||||
|
||||
- `REACT_AUDIO.NO_PROVIDER`
|
||||
- `REACT_AUDIO.PROVIDER_PENDING`
|
||||
- `REACT_AUDIO.UNKNOWN_PARAMETER`
|
||||
- `REACT_AUDIO.PRESET_STORE_FAILED`
|
||||
- `REACT_AUDIO.INVALID_OPTIONS`
|
||||
|
||||
## Subpath exports
|
||||
|
||||
```ts
|
||||
import { AudioProvider } from "@suaveplan/react-audio/provider";
|
||||
import { useTransport } from "@suaveplan/react-audio/hooks/use-transport";
|
||||
import { useAudioStore } from "@suaveplan/react-audio/stores";
|
||||
import { formatAriaValueText } from "@suaveplan/react-audio/a11y";
|
||||
import { ReactAudioError } from "@suaveplan/react-audio/error-codes";
|
||||
```
|
||||
|
||||
`./components` is reserved for Phase 2 and is **not** declared in
|
||||
Phase 1.
|
||||
|
||||
## Coming next
|
||||
|
||||
- **Phase 2 (`enterprise-react-audio-components`)** — Storybook-covered
|
||||
components: `<TransportControls>`, `<TrackList>`, `<PluginChainView>`,
|
||||
`<PluginSlot>`, `<MasterMeter>`, `<Mixer>`, `<PresetManager>`, …
|
||||
- **Phase 3 (`enterprise-react-audio-midi`)** — `useMidiController`
|
||||
hook + `<MidiControllerSetup>` learn-mode panel.

# `a11y/aria-value-text`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
Pure `aria-valuetext` formatter consumed by Phase-2 parameter
|
||||
controls (knobs, sliders, scrubbers). Returns a screen-reader
|
||||
friendly string for any numeric parameter value, picking sensible
|
||||
fractional digits from the parameter's declared range and applying
|
||||
unit-specific conventions (signed dB, kHz autoconversion above 1000
|
||||
Hz, percent suffix, ratio formatting, …).
|
||||
|
||||
The module has zero React or DOM imports so it is safe to use in
|
||||
universal contexts (tests, SSR, Storybook docs, isolation
|
||||
tools).
|
||||
|
||||
## Features
|
||||
|
||||
- Auto-derived fractional digits from value magnitude and parameter
|
||||
range (overridable via `options.fractionDigits`).
|
||||
- Signed dB with optional `+` prefix on positive values (default on).
|
||||
- Hz auto-promotion to kHz above 1000 Hz.
|
||||
- Built-in unit recognisers: `dB`, `Hz`, `kHz`, `ms`, `s`, `%`,
|
||||
`ratio`, `cents`, `semitones`, `samples`, `bpm`; arbitrary strings
|
||||
fall through with `${value.toFixed(digits)} ${unit}`.
|
||||
- Handles `Infinity` and `NaN` by returning `"out of range"`.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```ts
|
||||
import { formatAriaValueText } from "@suaveplan/react-audio/a11y";
|
||||
|
||||
formatAriaValueText(3.5, "dB", -12, 12); // "+3.50 dB"
|
||||
formatAriaValueText(880, "Hz", 20, 20000); // "880 Hz"
|
||||
formatAriaValueText(2400, "Hz", 20, 20000); // "2.40 kHz"
|
||||
formatAriaValueText(50, "%", 0, 100); // "50.0 %"
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
import { formatAriaValueText } from "@suaveplan/react-audio/a11y";
|
||||
|
||||
function ParameterReadout({
|
||||
value,
|
||||
unit,
|
||||
min,
|
||||
max,
|
||||
}: {
|
||||
value: number;
|
||||
unit: string;
|
||||
min: number;
|
||||
max: number;
|
||||
}) {
|
||||
return (
|
||||
<span aria-live="polite">
|
||||
{formatAriaValueText(value, unit, min, max, {
|
||||
fractionDigits: 1,
|
||||
})}
|
||||
</span>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
- `formatAriaValueText(value, unit, min, max, options?): string`.
|
||||
- `AriaValueUnit` — union of the recognised unit strings (plus the
|
||||
catch-all `string`).
|
||||
- `FormatAriaValueOptions = { fractionDigits?, signedDb? }`.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The auto-derived precision picks 0 digits for ranges ≥ 1000, 1 digit
|
||||
for ≥ 100, 2 digits for ≥ 1, and 3 digits otherwise. This matches
|
||||
screen-reader-friendly conventions: nobody wants to hear "two
|
||||
thousand four hundred point three two seven six Hertz". Hz values
|
||||
auto-promote to kHz at the 1000 Hz threshold because that's the
|
||||
boundary at which the kHz scale dominates audio production
|
||||
conventions; the kHz output uses a fixed 2-digit precision so values
|
||||
near the boundary read out consistently. `Infinity` and `NaN` short
|
||||
out to `"out of range"` because screen readers handle that phrase
|
||||
gracefully whereas spelling out `Infinity` derails the user.

# `a11y/keyboard-bindings`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
Pure-value table mapping keyboard keys to parameter-control actions
|
||||
(`fine-decrement`, `coarse-increment`, `page-decrement`, `min`,
|
||||
`max`, `enter-value`). Phase-2 components — knobs, sliders, the
|
||||
parameter inspector — consume this table directly so the keymap is
|
||||
declared in exactly one place and easy to audit for accessibility
|
||||
compliance.
|
||||
|
||||
The module is React-free; it exports a frozen array, two factor
|
||||
constants (`KEY_MODIFIER_FACTOR_SHIFT` = 10, `KEY_MODIFIER_FACTOR_ALT`
|
||||
= 0.1), and a helper `matchKeyBinding(event)` that resolves a
|
||||
`KeyboardEvent`-shaped value into `{ binding, compositeFactor }` or
|
||||
`undefined` for a no-match.
|
||||
|
||||
## Features
|
||||
|
||||
- `PARAMETER_KEY_BINDINGS` — frozen `ReadonlyArray<KeyBinding>`.
|
||||
- `KEY_MODIFIER_FACTOR_SHIFT`, `KEY_MODIFIER_FACTOR_ALT` — composable
|
||||
multipliers.
|
||||
- `matchKeyBinding(event)` — pure function, no DOM imports.
|
||||
- Standard a11y keymap (arrows, page-up/down, home, end, enter).
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```ts
|
||||
import { matchKeyBinding } from "@suaveplan/react-audio/a11y";
|
||||
|
||||
function onKey(event: KeyboardEvent) {
|
||||
const match = matchKeyBinding(event);
|
||||
if (match === undefined) return;
|
||||
console.log(match.binding.action, match.compositeFactor);
|
||||
}
|
||||
```

||||

||||
## Usage: Advanced

```
|

## API Reference
|
||||
|
||||
- `KeyBinding` — `{ key, action, factor, modifiers? }`.
|
||||
- `PARAMETER_KEY_BINDINGS: ReadonlyArray<KeyBinding>`.
|
||||
- `KEY_MODIFIER_FACTOR_SHIFT: 10`.
|
||||
- `KEY_MODIFIER_FACTOR_ALT: 0.1`.
|

- `matchKeyBinding(event): { binding, compositeFactor } | undefined`.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The keymap conventions (`←` fine, `↓` coarse, `Shift` ×10, `Alt`
|
||||
×0.1) match the design.md accessibility section so the upstream
|
||||
behaviour carries forward. The `matchKeyBinding` helper takes an
|
||||
event-shaped object rather than a `KeyboardEvent` so it is callable
|
||||
from test harnesses with plain object literals — and zero DOM types
|
||||
are imported into this file. The factor multiplication
|
||||
order is `binding.factor * shift * alt`; with both modifiers pressed
|
||||
the net effect is `factor × 10 × 0.1 = factor`, which is the
|
||||
intended "shift cancels alt" semantics.

# `<AudioPlayer>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<AudioPlayer>` is the generic media-player surface for a live
|
||||
`AudioPlayerPlugin` instance from
|
||||
`@suaveplan/audio-fx-plugin-audio-player`. It renders the full
|
||||
playback control surface — play / pause / stop / seek / volume / loop
|
||||
/ playback rate — bound directly to the plugin's dedicated mutators
|
||||
(`play`, `pause`, `stop`, `seek`, `setVolume`, `setLoop`,
|
||||
`setPlaybackRate`). State is sampled by polling `plugin.getState()` at
|
||||
the configured tick rate so the seek bar stays in sync with the
|
||||
audio-thread position.
|
||||
|
||||
The component is composed entirely against the plugin: there is no
|
||||
React-side cache of playback state. Loading is handled via the
|
||||
optional `src` prop which auto-calls `plugin.load(src)` on mount.
|
||||
|
||||
## Features
|
||||
|
||||
- Full control surface bound to plugin mutators.
|
||||
- Optional `src` triggers async `plugin.load(src)` on mount.
|
||||
- Surfaces plugin / load errors via an inline `role="alert"` element.
|
||||
- `showLoop` / `showPlaybackRate` props toggle the optional controls.
|
||||
- Live seek bar reflects `plugin.getState().currentTimeSec`.
|
||||
- Polls at `sampleRateHz` (default 30, clamped `>= 1`).
|
||||
- Unmounting cancels the in-flight `load()` so late resolutions cannot
|
||||
setState on a torn-down component.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioPlayerPlugin } from "@suaveplan/audio-fx-plugin-audio-player";
|
||||
import { AudioProvider, AudioPlayer } from "@suaveplan/react-audio";
|

<AudioPlayer plugin={plugin} />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```

## Implementation Notes
|
||||
|
||||
Errors thrown by the underlying plugin are caught at every mutation
|
||||
site and surfaced via a single `role="alert"` element so callers can
|
||||
style or speak the error consistently. The cancel-on-unmount guard
|
||||
uses a local `cancelled` flag captured in the effect closure rather
|
||||
than an `AbortController` because `plugin.load` does not expose its
|
||||
inner fetch signal; this still prevents the standard "setState on
|
||||
unmounted component" warning. State polling runs in a separate
|
||||
effect from the load effect so changing `src` does not restart the
|
||||
poll.

# `<AudioVisualizer>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<AudioVisualizer>` is a canvas-based visualiser for a published bus.
|
||||
It subscribes through the foundation `useBus` hook (default `"master"`)
|
||||
and renders one of three modes — waveform, spectrum, or level — into a
|
||||
`<canvas>` at the configured tick rate. The component is read-only and
|
||||
allocates exactly one scratch `Float32Array` per mount so the
|
||||
per-frame path is allocation-free in steady state.
|
||||
|
||||
The visualiser is intentionally agnostic about the source: anything
|
||||
that publishes to the named bus shows up. When no publisher exists
|
||||
the canvas paints the background only.
|
||||
|
||||
## Features
|
||||
|
||||
- Three modes: `"waveform"`, `"spectrum"`, `"level"`.
|
||||
- Configurable width, height, foreground colour, and background.
|
||||
- `sampleRateHz` controls the tick rate (clamped to `>= 1`).
|
||||
- `busName` selects which bus to render (default `"master"`).
|
||||
- `role="img"` + descriptive `aria-label` for screen readers.
|
||||
- Drawing primitives (`drawWaveform` / `drawSpectrum` / `drawLevel`)
|
||||
are individually exported as `@internal` for test coverage.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, AudioVisualizer } from "@suaveplan/react-audio";
|
||||
|
||||
export function App() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<AudioVisualizer />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, AudioVisualizer } from "@suaveplan/react-audio";
|
||||
|
||||
export function MultiVisualizer() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<AudioVisualizer mode="waveform" />
|
||||
<AudioVisualizer mode="spectrum" busName="auxA" />
|
||||
<AudioVisualizer
|
||||
mode="level"
|
||||
color="#0f0"
|
||||
backgroundColor="#000"
|
||||
width={128}
|
||||
height={32}
|
||||
sampleRateHz={120}
|
||||
/>
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ----------------- | ------------------- | ----------- | ---------------------------------------------- |
|
||||
| `className` | `string \| undef` | — | Forwarded to the `<canvas>`. |
|
||||
| `width` | `number \| undef` | `320` | Canvas pixel width. |
|
||||
| `height` | `number \| undef` | `80` | Canvas pixel height. |
|
||||
| `mode` | `VisualizerMode` | `"waveform"`| One of the three render modes. |
|
||||
| `busName` | `string \| undef` | `"master"` | Which bus to read. |
|
||||
| `sampleRateHz` | `number \| undef` | `60` | Render tick rate. |
|
||||
| `color` | `string \| undef` | `"#3aa"` | Foreground colour. |
|
||||
| `backgroundColor` | `string \| undef` | `"#111"` | Canvas background colour. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The effect resolves the canvas context once on mount via
|
||||
`canvas.getContext("2d")` and gracefully short-circuits when the
|
||||
context cannot be acquired (test environments without canvas support,
|
||||
or production browsers under aggressive accessibility settings). When
|
||||
the bus has no publisher the visualiser still ticks the canvas to
|
||||
keep the background paint fresh. Spectrum mode uses a naive average
|
||||
of `Math.abs` over a downsampled window rather than a real FFT — this
|
||||
is deliberate so the component has zero non-React runtime dependencies
|
||||
and remains universally portable.

# `<BasicPlayer>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<BasicPlayer>` is the minimal media-player surface for an
|
||||
`AudioPlayerPlugin`. It is implemented as a thin composition over
|
||||
`<AudioPlayer>` with the loop toggle and playback-rate input disabled,
|
||||
leaving only the essential controls: play / pause / stop / seek /
|
||||
volume. Use this when you want a clean, distraction-free player and
|
||||
don't need the advanced playback adjustments the full player exposes.
|
||||
|
||||
Because it is a strict composition, every behavioural guarantee of
|
||||
`<AudioPlayer>` — cancel-on-unmount, error surfacing, state polling —
|
||||
applies here unchanged.
|
||||
|
||||
## Features
|
||||
|
||||
- Forwards every relevant prop to `<AudioPlayer>`.
|
||||
- Hides the loop toggle and playback rate input.
|
||||
- Adds the `.rax-basic-player` class (or merges it with the supplied
|
||||
`className`) so theming targets are stable across the two surfaces.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioPlayerPlugin } from "@suaveplan/audio-fx-plugin-audio-player";
|
||||
import { AudioProvider, BasicPlayer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new AudioPlayerPlugin({});
|
||||
|
||||
export function Card() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<BasicPlayer plugin={plugin} src="https://cdn/short.wav" />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { AudioPlayerPlugin } from "@suaveplan/audio-fx-plugin-audio-player";
|
||||
import { AudioProvider, BasicPlayer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new AudioPlayerPlugin({});
|
||||
|
||||
export function MutedCard() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<BasicPlayer plugin={plugin} className="muted-row" />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```

||||

||||

||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ----------- | -------------------------- | ------- | ------------------------------------------- |
|
||||
| `plugin` | `AudioPlayerPlugin` | — | Required. |
|
||||
| `src` | `string \| undef` | — | Auto-load this URL on mount. |
|
||||
| `className` | `string \| undef` | — | Forwarded; merged with `rax-basic-player`. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The `showLoop` / `showPlaybackRate` props on the underlying
|
||||
`<AudioPlayer>` are fixed at `false`, which makes the BasicPlayer's
|
||||
prop signature smaller than the full player's. There is no separate
|
||||
state, no separate effect — every behavioural guarantee of the full
|
||||
player applies. Pass-through is deliberately verbose (one prop at a
|
||||
time) so future additions to `<AudioPlayer>` do not silently widen
|
||||
`<BasicPlayer>`'s surface; new props must be added explicitly.

# `<GLaDOSControls>`
|

|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<GLaDOSControls>` is the composed UI for the `GLaDOSPlugin` voice
|
||||
transform from `@suaveplan/audio-fx-plugin-glados`. The plugin
|
||||
defines a six-stage voice pipeline (pitch shift, formant shift,
|
||||
robotic intensity, distortion, low-pass cutoff, reverb amount) plus
|
||||
six built-in presets covering the GLaDOS, Wheatley, Cave Johnson, and
|
||||
generic robotic voices. This component surfaces all six stages as
|
||||
range inputs and the preset list as a `<select>`.
|
||||
|
||||
The component is intentionally a thin shell over the plugin: every
|
||||
edit calls the plugin's named setter (`setPitchShift`,
|
||||
`setFormantShift`, etc.), every preset switch calls
|
||||
`applyGladosPreset`. There is no React-side cache that could drift
|
||||
from the plugin's authoritative config.
|
||||
|
||||
## Features
|
||||
|
||||
- Six stage sliders with plugin-defined ranges.
|
||||
- Preset `<select>` covering all six built-ins.
|
||||
- Errors from stage setters (out-of-range values) surfaced via
|
||||
`role="alert"`; cleared when the next successful edit or preset
|
||||
change lands.
|
||||
- Live readout next to every slider.
|
||||
- `data-stage` attributes on every stage for theming hooks.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { GLaDOSPlugin } from "@suaveplan/audio-fx-plugin-glados";
|
||||
import { AudioProvider, GLaDOSControls } from "@suaveplan/react-audio";

|

|
||||
## Implementation Notes
|
||||
|
||||
The stage table is declared once at module scope so React's diff
|
||||
sees stable identities across renders. Each stage carries its own
|
||||
`min` / `max` / `step` and the plugin setter to invoke; on every
|
||||
change we parse the input value, dispatch to the setter inside a
|
||||
try/catch, and re-read the plugin's config snapshot. Errors are
|
||||
captured as plain strings to keep the error surface portable across
|
||||
runtimes (no SuaveplanError dependency at this layer). Preset
|
||||
switches always clear the prior error because the new preset is a
|
||||
known-good config.

# `parameter-keyboard`
|
||||
|
||||
Internal helper consumed by `<PluginParameterKnob>` and
|
||||
`<PluginParameterSlider>` to translate a `KeyboardEvent` into a clamped
|
||||
next parameter value. The helper is a pure function — no React, no DOM
|
||||
— so it is fully unit-testable without rendering a tree.
|
||||
|
||||
## Purpose
|
||||
|
||||
The `<PluginSlot>` accessibility requirement mandates an identical
|
||||
keyboard contract on every parameter control: arrow keys for fine /
|
||||
coarse adjustments, `PageUp`/`PageDown` for ×10 coarse, `Home`/`End` for
|
||||
range endpoints, `Enter` for type-edit, plus `Shift` ×10 and `Alt` ÷10
|
||||
modifiers. Reimplementing this contract in two component files would
|
||||
double the surface area subject to drift. The shared helper guarantees
|
||||
both primitives interpret the keymap identically.
|
||||
|
||||
## Features
|
||||
|
||||
- 1 % step base ×1, ×10, ×100 binding factors (from `PARAMETER_KEY_BINDINGS`).
|
||||
- `Shift` multiplier ×10, `Alt` multiplier ÷10.
|
||||
- Clamping to `[min, max]` on every increment, decrement, and `Home`/`End` jump.
|
||||
- Returns the matching `KeyBinding` so the caller can detect the special
|
||||
`Enter` action and open a type-edit affordance.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```ts
|
||||
import { resolveParameterKeyboardChange } from "./parameter-keyboard.js";
|
||||
|
||||
const result = resolveParameterKeyboardChange(
|
||||
{ key: "ArrowRight", shiftKey: false, altKey: false },
|
||||
0,
|
||||
-24,
|
||||
24
|
||||
);
|
||||
// result.handled === true; result.next === 0.48 (1 % of 48)
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```ts
|
||||
// Compose with the React keyboard handler in <PluginParameterKnob>:
|
||||
function onKeyDown(event: React.KeyboardEvent<HTMLDivElement>) {
|
||||
const out = resolveParameterKeyboardChange(event, value, min, max);
|
||||
if (!out.handled) return;
|
||||
event.preventDefault();
|
||||
if (out.binding?.action === "enter-value") {
|
||||
setEditing(true);
|
||||
return;
|
||||
}
|
||||
onChange(out.next);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
- `resolveParameterKeyboardChange(event, current, min, max) → ParameterKeyboardResult`
|
||||
- `event` — `{ key, shiftKey, altKey }`; matches the shape of `KeyboardEvent`.
|
||||
- `current` — current numeric value.
|
||||
- `min` / `max` — declared parameter range.
|
||||
- `ParameterKeyboardResult` — `{ handled, next, binding }`.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The function iterates `PARAMETER_KEY_BINDINGS` in declaration order.
|
||||
Adding new bindings is purely declarative — the helper picks them up
|
||||
for free.
|
||||
- `Home`/`End` deliberately ignore the modifier multipliers; they are
|
||||
endpoint jumps, not stepped moves.
|
||||
- The function never throws; an unrecognised key returns
|
||||
`{ handled: false, next: current, binding: undefined }` so the caller
|
||||
can fall through to other listeners.

# `parameter-unit`
|
||||
|
||||
Internal helper that converts the controlled `ParameterUnit` enum
|
||||
exposed by `@suaveplan/audio-fx-plugin-base` (`"db"`, `"hz"`, `"ms"`,
|
||||
`"percent"`, …) into the display string the `formatAriaValueText` a11y
|
||||
helper expects (`"dB"`, `"Hz"`, …). Centralising the mapping in a
|
||||
single helper guarantees every parameter control under `<PluginSlot>`
|
||||
formats `aria-valuetext` consistently regardless of which primitive
|
||||
(`<PluginParameterKnob>`, `<PluginParameterSlider>`) renders it.
|
||||
|
||||
## Purpose
|
||||
|
||||
The audio-plugin contract uses a small controlled lowercase enum so
|
||||
plugin authors cannot drift into ad-hoc spellings. The a11y formatter
|
||||
prefers the human-display capitalisation (dB, Hz, kHz, BPM). The
|
||||
adapter function bridges the two without forcing either side to bend.
|
||||
|
||||
## Features
|
||||
|
||||
- Total function over the `ParameterUnit` enum (no missing branches).
|
||||
- Returns `""` for `"enum"` parameters since their values are not
|
||||
numeric ranges.
|
||||
- Safe on `undefined` — returns `""` so the formatter falls through to
|
||||
its default branch and renders the bare numeric value.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```ts
|
||||
import { mapParameterUnitForAria } from "./parameter-unit.js";
|
||||
import { formatAriaValueText } from "../../a11y/aria-value-text/aria-value-text.js";
|
||||
|
||||
const aria = formatAriaValueText(
|
||||
plugin.getParameter("frequency"),
|
||||
mapParameterUnitForAria(parameter.unit),
|
||||
parameter.min,
|
||||
parameter.max
|
||||
);
|
||||
// "880 Hz" for { unit: 'hz', value: 880 }
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```ts
|
||||
// Inside <PluginParameterKnob>, render aria-valuetext from the mapped unit:
|
||||
const ariaUnit = mapParameterUnitForAria(parameter.unit);
|
||||
const valuetext = formatAriaValueText(value, ariaUnit, min, max, {
|
||||
signedDb: true,
|
||||
});
|
||||
return <div role="slider" aria-valuetext={valuetext} ... />;
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
- `mapParameterUnitForAria(unit: ParameterUnit | undefined): AriaValueUnit`
|
||||
— pure function; total over the enum; defaults to `""`.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The function intentionally returns a `string` (`AriaValueUnit` is a
|
||||
string union widened by `| string`), so adding a new audio-side
|
||||
`ParameterUnit` value will surface as a TypeScript exhaustiveness
|
||||
warning on the `switch` in this file only — the formatter does not
|
||||
need to change.
|
||||
- No allocations — the function returns string literals.

# `<MasterMeter>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<MasterMeter>` is a RAF-sampled master-output level meter. It
|
||||
subscribes to a named sidechain bus through the foundation `useBus`
|
||||
hook (`"master"` by default) and continuously reads the bus's
|
||||
block-aligned PCM into a scratch buffer at the configured interval,
|
||||
deriving per-channel peak and RMS levels in dB and a slow-decaying
|
||||
peak-hold envelope. When no publisher exists for the bus, every
|
||||
channel shows silence (`-∞` dB) so consumers always see something.
|
||||
|
||||
The meter is intentionally side-effect-free with respect to the audio
|
||||
graph: it only reads. Nothing inside `<MasterMeter>` ever writes to the
|
||||
bus or mutates engine state, which keeps it safe to drop into any
|
||||
layout that already has a publisher upstream.
|
||||
|
||||
## Features
|
||||
|
||||
- Subscribes to any named bus via `useBus(busName)`.
|
||||
- Per-channel peak + RMS in dB, plus a peak-hold envelope.
|
||||
- Configurable channel count, sample-tick rate, and hold time.
|
||||
- Reads up to `Math.min(meterChannels, busChannels)` per tick so
|
||||
publisher-wider and meter-wider mismatches do not blow up.
|
||||
- `role="meter"` + `aria-label` for screen readers.
|
||||
- `data-bus` and `data-channel` attributes for theming hooks.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, MasterMeter } from "@suaveplan/react-audio";
|
||||
|
||||
export function App() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<MasterMeter />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, MasterMeter } from "@suaveplan/react-audio";
|
||||
|
||||
export function AuxMeter() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<MasterMeter
|
||||
busName="auxA"
|
||||
channels={1}
|
||||
sampleRateHz={120}
|
||||
peakHoldMs={2000}
|
||||
className="aux-meter"
|
||||
/>
|
||||
</AudioProvider>
|
||||
);
|
||||
}

||||
```

|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<div>`. |
|
||||
| `busName` | `string \| undef` | `"master"` | Name of the bus to subscribe to. |
|
||||
| `channels` | `number \| undef` | `2` | Number of channel rows to render. |
|
||||
| `sampleRateHz` | `number \| undef` | `60` | UI sample tick rate. Clamped to `>= 1`. |
|
||||
| `peakHoldMs` | `number \| undef` | `1000` | Peak-hold decay time in milliseconds. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component allocates one persistent scratch `Float32Array[]` per
|
||||
mount sized to `channelCount × 128` so the per-tick read does not
|
||||
allocate. Bus channel mismatches are handled by reading only the
|
||||
narrower side: if the publisher is wider than the meter, only the
|
||||
leading channels are read; if the meter is wider than the publisher,
|
||||
the trailing channels keep their zero-fill from the scratch buffer's
|
||||
last write (which corresponds to silence on next dB conversion). The
|
||||
peak-hold envelope uses one mutable record per channel keeping the
|
||||
current hold value and its expiry timestamp; the value is replaced
|
||||
either when a louder peak arrives or when the hold window expires,
|
||||
which gives the visually slow decay typical of professional meters.

# `<MicrophoneControls>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<MicrophoneControls>` is the composed UI for
|
||||
`MicrophoneSimulationPlugin` from
|
||||
`@suaveplan/audio-fx-plugin-microphone`. The plugin itself declares
|
||||
its UI surface via `getUISections()`: a list of grouped controls
|
||||
(frequency, resonance, distortion, noise, dynamics, gain, character,
|
||||
wow/flutter) with their numeric ranges and step sizes. The component
|
||||
mirrors that data-driven structure, rendering one `<fieldset>` per
|
||||
section and one `<input type="range">` per control. Writes go through
|
||||
`plugin.setMicrophoneConfig` with the minimal partial-update.
|
||||
|
||||
Because the UI structure is driven entirely by the plugin's metadata,
|
||||
adding a new control on the plugin automatically shows up here — no
|
||||
React code change required.
|
||||
|
||||
## Features
|
||||
|
||||
- Data-driven layout from `plugin.getUISections()`.
|
||||
- One range input per declared control, with `min` / `max` / `step`
|
||||
taken from the plugin's metadata.
|
||||
- Live readout shown alongside every slider via `aria-live="polite"`.
|
||||
- Non-numeric input ignored to keep the plugin config schema-valid.
|
||||
- `aria-label="Microphone controls"` on the outer section and
|
||||
per-control labels in the form `"<group> <control>"`.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { MicrophoneSimulationPlugin } from "@suaveplan/audio-fx-plugin-microphone";
|
||||
import {
|
||||
AudioProvider,
|
||||
MicrophoneControls,
|
||||
} from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new MicrophoneSimulationPlugin();
|
||||
|
||||
export function App() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<MicrophoneControls plugin={plugin} />
|
||||
</AudioProvider>
|
||||
);

|
||||
| `plugin` | `MicrophoneSimulationPlugin` | — | Required. |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<section>`. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component stores a single config snapshot in React state and
|
||||
refreshes it on every successful write. Section / control ids are
|
||||
exposed via `data-section` / per-control keys so consumers can target
|
||||
any cell with CSS without inspecting the plugin's metadata. The
|
||||
`updateField` helper constructs a minimal partial-update of the form
|
||||
`{ [group]: { ...prev[group], [field]: newValue } }`, which keeps
|
||||
unrelated group fields stable across the `setMicrophoneConfig` call;
|
||||
the plugin's own merge logic then folds the partial into its live
|
||||
config tree.

|

<!-- begin:auto-docs -->

_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<MidiControllerSetup>` is the Phase-3 learn-mode panel for the
|
||||
Suaveplan React audio stack. It renders the connected controllers
|
||||
from a `MidiControllerRegistry` (supplied either via the
|
||||
`controllers` prop or via the surrounding
|
||||
`MidiControllerRegistryContext`), pairs them with a target picker
|
||||
built from the supplied `plugins`, and arranges the captured
|
||||
`(channel, controller)` pair against the parameter chosen by the
|
||||
user. Each established binding is materialised through
|
||||
`bindParameter` from `@suaveplan/audio-controllers` and persisted via
|
||||
the same `PresetStore` the `<PresetManager>` consumes, so the bindings
|
||||
re-bind on next mount.
|
||||
|
||||
The component is intentionally lean: it does not own the controller
|
||||
hardware nor the MIDI access — it composes the live
|
||||
`MidiControllerPlugin` instance the application has already
|
||||
constructed at startup. This keeps the lifecycle ownership in one
|
||||
place and matches the rest of the Phase-2 component family.
|
||||
|
||||
## Features
|
||||
|
||||
- Controller / plugin / parameter picker rendered via accessible
|
||||
`<select>` elements with `aria-label`s on each control.
|
||||
- `Learn` button enters learn-mode through `useMidiController`'s
|
||||
`learn(target)` method.
|
||||
- Captured CC is bound through `bindParameter` with the optional
|
||||
`smoothingMs` forwarded to the binding helper.
|
||||
- Active bindings are rendered as an `<ul>` with `Unbind` buttons.
|
||||
`Unbind` calls the unsubscribe function returned by `bindParameter`.
|
||||
- Bindings are persisted under `presetKey` (default
|
||||
`midi-controller-setup`) through the provider's `presetStore`.
|
||||
- On mount, persisted bindings are rehydrated and re-bound.
|
||||
- Live `state` indicator next to the Learn button mirrors the
|
||||
controller FSM (`disconnected → connecting → connected → error`).
|
||||
- Renders an `data-empty="true"` empty state when no controllers are
|
||||
registered.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import {
|
||||
MidiControllerRegistryContext,
|
||||
MidiControllerSetup,
|
||||
} from "@suaveplan/react-audio";
|
||||
|
||||
function MidiPanel({ controllers, plugins }) {
|
||||
return (
|
||||
<MidiControllerRegistryContext.Provider value={controllers}>
|
||||
<MidiControllerSetup plugins={plugins} />
|
||||
</MidiControllerRegistryContext.Provider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
import { MidiControllerSetup } from "@suaveplan/react-audio";
|
||||
|
||||
function AdvancedMidi({ controllers, plugins }) {
|
||||
return (
|
||||
<MidiControllerSetup
|
||||
plugins={plugins}
|
||||
controllers={controllers}
|
||||
smoothingMs={25}
|
||||
presetKey="studio-bindings"
|
||||
className="studio-midi"
|
||||
/>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Persisted bindings are stored under the `"chain"` kind in the
|
||||
`PresetStore` so any store implementation that already serves chain
|
||||
snapshots transparently serves binding lists too. The payload shape
|
||||
is `{ bindings: MidiBinding[] }`; consumers can inspect the same
|
||||
key from a sibling tool without involving the React surface.
|
||||
|
||||
## API Reference
|
||||
|
||||
- `MidiControllerSetupProps.plugins` — `ReadonlyArray<AudioFxPlugin>`
|
||||
whose `parameterIndex` entries become the parameter picker.
|
||||
- `MidiControllerSetupProps.controllers` — optional explicit
|
||||
`MidiControllerRegistry`; takes precedence over context.
|
||||
- `MidiControllerSetupProps.smoothingMs` — forwarded to
|
||||
`bindParameter`. Defaults to `0`.
|
||||
- `MidiControllerSetupProps.presetKey` — preset-store key for the
|
||||
persisted binding list. Defaults to `midi-controller-setup`.
|
||||
- `MidiControllerSetupProps.className` — CSS class forwarded to the
|
||||
outer `<section>`.
|
||||
- `MidiBinding` — `{ controllerId, pluginId, paramId, source,
|
||||
smoothingMs? }`. The persisted payload shape.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component composes `useMidiController(controllerId, registry)`
|
||||
to source the live controller and its FSM state, then forwards the
|
||||
captured CC into `bindParameter`. Because `bindParameter` returns an
|
||||
`UnsubscribeFn`, the component stores those handles alongside the
|
||||
binding metadata and tears them all down on unmount via a `useRef`
|
||||
snapshot to avoid the classic "stale-effect-cleanup" pitfall where
|
||||
the cleanup closure captures an out-of-date `active` list. Errors
|
||||
from either learn capture or `bindParameter` are surfaced through a
|
||||
non-blocking inline `role="alert"` paragraph rather than thrown so
|
||||
the panel keeps rendering when one binding fails.

# `<Mixer>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<Mixer>` is the per-channel strip view for a live `MixerPlugin`
|
||||
instance from `@suaveplan/audio-fx-plugin-mixer`. It renders one row
|
||||
per channel (gain + pan slider + live VU readout) plus an optional
|
||||
master gain row. Channel writes are routed through the plugin's
|
||||
`setChannelGain` / `setChannelPan` methods; the master row binds the
|
||||
plugin's `"masterGain"` parameter via the foundation `useParameter`
|
||||
hook so external automation surfaces (curves, presets, recall) keep
|
||||
working transparently.
|
||||
|
||||
The Mixer composition exists to make the audio plugin the source of
|
||||
truth — there is no React-side store of channel state. Every commit
|
||||
samples the plugin via `getChannels()` so swapping the plugin (e.g.
|
||||
via a `<PluginLoader>`) immediately updates the visible strips.
|
||||
|
||||
## Features
|
||||
|
||||
- One row per channel returned by `plugin.getChannels()`.
|
||||
- Per-channel gain (range `0..4`) and pan (range `-1..1`) sliders.
|
||||
- Master gain row bound to the plugin's `"masterGain"` parameter.
|
||||
- Per-channel VU readout from `plugin.getVuLevels()`, refreshed at
|
||||
`vuSampleRateHz` (default 30, clamped `>= 1`).
|
||||
- `aria-label` on every input plus a `role="list"` strip container.
|
||||
- `hideMaster` suppresses the master row for embedded usage.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { MixerPlugin } from "@suaveplan/audio-fx-plugin-mixer";
|
||||
import { AudioProvider, Mixer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new MixerPlugin({
|
||||
channels: [{ id: "drums" }, { id: "bass" }, { id: "vox" }],
|
||||
});
|
||||
|
||||
export function App() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<Mixer plugin={plugin} />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { MixerPlugin } from "@suaveplan/audio-fx-plugin-mixer";
|
||||
import { AudioProvider, Mixer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new MixerPlugin({
|
||||
channels: [
|
||||
{ id: "guitar", initialGain: 0.8, initialPan: -0.3 },
|
||||
{ id: "bass", initialGain: 0.7 },
|
||||
],
|
||||
initialMasterGain: 1.2,
|
||||
});
|
||||
|
||||
export function Workstation() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<Mixer plugin={plugin} vuSampleRateHz={60} hideMaster />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```

||||
|
||||
## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ----------------- | ------------------- | ------- | ------------------------------------------------ |
|
||||
| `plugin` | `MixerPlugin` | — | Required. The live mixer plugin instance. |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<section>`. |
|
||||
| `hideMaster` | `boolean \| undef` | `false` | Hides the master row when `true`. |
|
||||
| `vuSampleRateHz` | `number \| undef` | `30` | UI tick rate for VU + channel snapshots. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component does not stash channel state in React: every interval
|
||||
tick re-reads `plugin.getChannels()` and `plugin.getVuLevels()` into
|
||||
the local snapshot used for rendering. Channel mutations go through
|
||||
the plugin's mutators (`setChannelGain` / `setChannelPan`) and
|
||||
immediately re-read so the next render reflects the change without
|
||||
waiting for the interval. Master gain is treated as a normal plugin
|
||||
parameter so curves and presets work transparently. The VU snapshot
|
||||
sample rate is clamped to `>= 1 Hz` to defeat divide-by-zero on
|
||||
`setInterval` and survives `vuSampleRateHz={0}` without crashing.

# `<PluginChainView>`
|
||||
|
||||
Reorderable, accessible view of a `PluginChain`. Renders one
|
||||
`<PluginSlot>` per chain entry, supports HTML5 drag-and-drop with a
|
||||
full keyboard alternative, exposes an "Add FX" picker filtered against
|
||||
the chain's effective channel count, and surfaces any rejection from
|
||||
`chain.add()` / `chain.move()` as a non-blocking toast carrying the
|
||||
underlying `AudioFxError`'s `code`.
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<PluginChainView>` is the workhorse list component for the audio
|
||||
workspace. It owns no plugin instances directly — every plugin is
|
||||
created by the provider's `PluginRegistry` and added to the chain via
|
||||
the Phase-1 `usePluginChain` hook. The view re-renders on every
|
||||
`plugin-added` / `plugin-removed` / `plugin-moved` / `plugin-replaced`
|
||||
/ `bypass-changed` event because `usePluginChain` subscribes to all
|
||||
five.
|
||||
|
||||
## Features
|
||||
|
||||
- HTML5 DnD: `draggable` slots; `onDragStart` carries the source
|
||||
index; `onDrop` reads the index and dispatches `chain.move()`.
|
||||
- Accepts external drops carrying a `application/x-audio-fx-type`
|
||||
payload (e.g. from a separate plugin browser) and inserts at the
|
||||
target index.
|
||||
- Keyboard reorder: `Space` picks up the focused slot, `↑`/`↓` move
|
||||
the hover marker, `Enter` drops, `Escape` cancels.
|
||||
- IO-aware "Add FX" picker — `PluginRegistry.list()` filtered against
|
||||
the chain's current effective output channel count via the plugin's
|
||||
declared `io.inputs[0].count`.
|
||||
- Toast surfaces with `role="status"`, `data-code` attribute, and a
|
||||
dismiss control. Toast clears when the user clicks Dismiss.
|
||||
- `data-track-id` on the wrapper, `data-picked` and
|
||||
`data-hover-target` on slots, `aria-grabbed` on the active slot.
|
||||
- CSS-class API only (`rax-chain`, `rax-chain__header`,
|
||||
`rax-chain__list`, `rax-chain__item`, `rax-chain__picker`,
|
||||
`rax-chain__toast`).
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import { PluginChainView } from "@suaveplan/react-audio/components/plugin-chain-view";
|
||||
|
||||
function TrackPanel({ trackId }) {
|
||||
return <PluginChainView trackId={trackId} />;
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
// Read-only chain preview with the picker hidden, themed wrapper.
|
||||
function ChainPreview({ trackId }) {
|
||||
return (
|
||||
<PluginChainView
|
||||
trackId={trackId}
|
||||
hideAddPicker
|
||||
className="ring-1 ring-zinc-700 rounded-md p-2"
|
||||
/>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Props
|
||||
|
||||
- `trackId: string` — passed to `usePluginChain` to resolve the chain.
|
||||
- `className?: string` — CSS class appended to the wrapper.
|
||||
- `hideAddPicker?: boolean` — when `true`, the "Add FX" picker button
|
||||
and menu are not rendered.
|
||||
|
||||
### Events surfaced
|
||||
|
||||
- A rejection from `chain.add()` or `chain.move()` produces a toast
|
||||
with the `AudioFxError.code` (e.g.
|
||||
`AUDIO_FX.CHAIN_IO_INCOMPATIBLE`).
|
||||
- Successful insertion / reorder / removal updates the list via the
|
||||
Phase-1 chain-event subscription.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The picker probes each registered type by calling
|
||||
`registry.create()` once, inspecting `io.inputs[0].count`, then
|
||||
disposing the probe instance. The cost is amortised across the
|
||||
picker open/close lifecycle.
|
||||
- Keyboard reorder uses local state for the picked-up index and a
|
||||
separate "hover" index so the user can see the prospective drop
|
||||
target before committing.
|
||||
- The HTML5 DnD handler clears its drag data on every render so a
|
||||
cancelled drag does not leak into the next interaction.
|
||||
- The toast is a single most-recent error — multiple errors collapse
|
||||
into one. This keeps the surface deterministic without depending on
|
||||
a toast queue library.

# `<PluginLoader>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<PluginLoader>` is the dynamic plugin-registration UI over the
|
||||
provider's `PluginRegistry`. It lists every currently-registered
|
||||
`pluginType`, lets the user pick one and click "Create" to
|
||||
instantiate it via `registry.create(...)`, and exposes a small
|
||||
registration form for adding new factories at runtime. It is the
|
||||
canonical surface for development panels and demo applications that
|
||||
want to swap plugins in and out without restarting the provider.
|
||||
|
||||
In production, callers typically pre-register their factories via the
|
||||
provider's `options.plugins` array — `<PluginLoader>` then acts as a
|
||||
purely informational dashboard showing what's available, with the
|
||||
"Create" button delegating to the registry's standard factory
|
||||
contract.
|
||||
|
||||
## Features
|
||||
|
||||
- Lists every registered `pluginType` from `PluginRegistry.list()`.
|
||||
- `<select>` picker bound to a local "selected" state.
|
||||
- "Create" button invokes `registry.create(...)`, catches and
|
||||
surfaces the registry's `AUDIO_FX.PLUGIN_TYPE_NOT_REGISTERED`
|
||||
error via a `role="alert"` element.
|
||||
- Optional `onCreated` callback receives the constructed plugin so
|
||||
parent components can wire it into a chain.
|
||||
- Inline registration form for adding placeholder factories at
|
||||
runtime (mainly for dev surfaces).
|
||||
- Empty-state handling when no plugins are registered.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, PluginLoader } from "@suaveplan/react-audio";
|
||||
|
||||
export function DevPanel() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<PluginLoader />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import {
|
||||
AudioProvider,
|
||||
PluginLoader,
|
||||
usePluginChain,
|
||||
} from "@suaveplan/react-audio";
|
||||
|
||||
export function WiredLoader() {
|
||||
const chain = usePluginChain("master");
|
||||
return (
|
||||
<AudioProvider>
|
||||
<PluginLoader
|
||||
onCreated={(plugin) => chain.add(plugin)}
|
||||
className="dev-loader"
|
||||
/>
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||

||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ------------ | ------------------------------------------------- | ------- | ------------------------------------------- |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<section>`. |

| `onCreated` | `(plugin, pluginType) => void` | — | Called when "Create" succeeds. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The registry is the source of truth: every render re-reads
|
||||
`registry.list()` so newly-registered factories show up immediately
|
||||
without needing a snapshot store. The component keeps a local
|
||||
`version` counter that is incremented after every registration so
|
||||
React schedules a re-render — `list()` itself is a method, not a
|
||||
reactive primitive. The registration form intentionally writes a
|
||||
*placeholder* factory that throws when invoked; this prevents the
|
||||
loader from accidentally being used in production to register
|
||||
half-real factories. Consumers wanting real registration should call
|
||||
`registry.register(...)` directly from a parent component.

# `<PluginParameterKnob>`
|
||||
|
||||
Rotary-knob primitive for a single `AudioFxPlugin` parameter. The knob
|
||||
implements the full keyboard contract mandated by the
|
||||
`<PluginSlot>` accessibility requirement, exposes `role="slider"` with
|
||||
ARIA range metadata derived from the parameter's `min`/`max`/`unit`
|
||||
declaration, and supports an `Enter`-to-edit type-in affordance.

parameter-control surface. Specialised plugin UIs (an EQ panel, a
|
||||
compressor panel) often wrap the knob with their own visual chrome
|
||||
while reusing the keyboard, ARIA, and value-management logic. The
|
||||
knob is therefore deliberately presentational: the entire keyboard
|
||||
keymap, value clamping, and typed-edit flow live here, while the
|
||||
caller supplies the plugin and parameter declaration.
|
||||
|
||||
The knob subscribes to the parameter via the Phase-1
|
||||
`useParameter` hook, so every change is reflected at the provider's
|
||||
declared `sampleRateHz` — by default 60 Hz, matching one tick per
|
||||
animation frame.
|
||||
|
||||
## Features
|
||||
|
||||
- `role="slider"`, `aria-valuemin`, `aria-valuemax`, `aria-valuenow`,
|
||||
`aria-valuetext` (unit-aware via `formatAriaValueText`).
|
||||
- `←`/`→` fine step (1 % of range), `↑`/`↓` coarse step (10 %),
|
||||
`PageUp`/`PageDown` ×100 page step, `Home`/`End` jump to range
|
||||
endpoints.
|
||||
- `Shift` ×10, `Alt` ÷10 modifier multipliers.
|
||||
- `Enter` opens a numeric type-edit input; `Enter` commits, `Escape`
|
||||
reverts, blur commits.
|
||||
- `data-parameter-id` attribute on the wrapper so plugin authors can
|
||||
target specific knobs from a stylesheet.
|
||||
- Pure CSS-class API (`rax-knob`, `rax-knob__dial`, `rax-knob__readout`,
|
||||
`rax-knob__input`) — no styling assumptions baked in.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import { PluginParameterKnob } from "@suaveplan/react-audio/components/plugin-parameter-knob";
|
||||
|
||||
function GainKnob({ plugin }) {
|
||||
const param = plugin.parameterIndex.get("gain")!;
|
||||
return <PluginParameterKnob plugin={plugin} parameter={param} />;
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
// Iterate every parameter on a plugin, rendering each with a custom label
|
||||
// override and theming via the className API.
|
||||
function PluginPanel({ plugin }) {
|
||||
return (
|
||||
<div className="grid grid-cols-4 gap-4">
|
||||
{plugin.parameters.map((p) => (
|
||||
<PluginParameterKnob
|
||||
key={p.id}
|
||||
plugin={plugin}
|
||||
parameter={p}
|
||||
label={p.name.toUpperCase()}
|
||||
className="ring-1 ring-zinc-700 rounded-md p-2"
|
||||
/>
|
||||
))}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Props
|
||||
|
||||
- `plugin: AudioFxPlugin` — the plugin instance whose parameter is bound.
|
||||
- `parameter: PluginParameter` — the declaration to render. The parameter
|
||||
MUST be present in `plugin.parameterIndex`; otherwise the underlying
|
||||
`useParameter` hook throws `REACT_AUDIO.UNKNOWN_PARAMETER`.
|
||||
- `label?: string` — optional visible label override; defaults to
|
||||
`parameter.name`.
|
||||
- `className?: string` — optional CSS class appended to the wrapper.
|
||||
|
||||
### Behaviour
|
||||
|
||||
- Each parameter update flows through `param.set(...)`, which delegates
|
||||
to `plugin.setParameter`. Value subscriptions go through the
|
||||
Phase-1 `useParameter` hook.
|
||||
- The typed-edit input is rendered only when the user presses `Enter`
|
||||
on the knob; it auto-focuses, supports `Enter`/`Escape`/blur, and
|
||||
clamps the parsed value to the declared range.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The keyboard handler delegates to the pure `resolveParameterKeyboardChange`
|
||||
helper, which is shared with `<PluginParameterSlider>` to guarantee
|
||||
identical step semantics between the two primitives.
|
||||
- `formatAriaValueText` is called with `signedDb: true` so dB readouts
|
||||
carry the `+` sign — matching the convention used by every other
|
||||
audio tool that ships unit-aware screen-reader text.
|
||||
- No animation libraries are imported; visual rotation should be
|
||||
composed by the consumer via CSS. The component respects
|
||||
`prefers-reduced-motion` by virtue of being CSS-only.

# `<PluginParameterSlider>`
|
||||
|
||||
Linear-slider primitive for a single `AudioFxPlugin` parameter.
|
||||
Mirrors `<PluginParameterKnob>`'s a11y contract and exposes a native
|
||||
`<input type="range">` for pointer drag while implementing the
|
||||
mandated keyboard keymap directly so step semantics match the knob.
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
The `<PluginParameterSlider>` is the linear half of the generic
|
||||
parameter-control surface. It is preferred over the knob when the
|
||||
parameter is naturally horizontal — pan, dry/wet mix, threshold,
|
||||
crossfeed — and when consumers want native touch / pointer drag
|
||||
without an extra dependency.
|
||||
|
||||
The slider subscribes to the parameter via the Phase-1
|
||||
`useParameter` hook, so per-block parameter updates flow to the UI at
|
||||
the provider's configured `sampleRateHz`.
|
||||
|
||||
## Features
|
||||
|
||||
- Native `<input type="range">` for pointer & touch drag, with `step`
|
||||
set to `(max - min) / 100` so drag granularity matches the keyboard
|
||||
fine-step.
|
||||
- `role="slider"`, `aria-valuemin`, `aria-valuemax`, `aria-valuenow`,
|
||||
`aria-valuetext` (unit-aware via `formatAriaValueText`).
|
||||
- Full keyboard keymap: `←`/`→`, `↑`/`↓`, `PageUp`/`PageDown`,
|
||||
`Home`/`End`, `Shift` ×10, `Alt` ÷10. Identical semantics to the
|
||||
knob.
|
||||
- `orientation` prop (`"horizontal"` | `"vertical"`) reflected on the
|
||||
wrapper as `data-orientation`.
|
||||
- `data-parameter-id` for stylesheet targeting.
|
||||
- CSS-class API only (`rax-slider`, `rax-slider__input`,
|
||||
`rax-slider__label`, `rax-slider__readout`).
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import { PluginParameterSlider } from "@suaveplan/react-audio/components/plugin-parameter-slider";
|
||||
|
||||
function MixSlider({ plugin }) {
|
||||
const param = plugin.parameterIndex.get("mix")!;
|
||||
return <PluginParameterSlider plugin={plugin} parameter={param} />;
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
// Render a vertical pan slider with a themed wrapper.
|
||||
function PanSlider({ plugin }) {
|
||||
const param = plugin.parameterIndex.get("pan")!;
|
||||
return (
|
||||
<PluginParameterSlider
|
||||
plugin={plugin}
|
||||
parameter={param}
|
||||
orientation="vertical"
|
||||
label="PAN"
|
||||
className="ring-1 ring-zinc-700 rounded-md p-2"
|
||||
/>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Props
|
||||
|
||||
- `plugin: AudioFxPlugin` — the plugin instance bound to the slider.
|
||||
- `parameter: PluginParameter` — the declaration to render. MUST be
|
||||
present in `plugin.parameterIndex`.
|
||||
- `orientation?: "horizontal" | "vertical"` — visual layout hint;
|
||||
defaults to `"horizontal"`.
|
||||
- `label?: string` — optional visible label override; defaults to
|
||||
`parameter.name`.
|
||||
- `className?: string` — optional CSS class appended to the wrapper.
|
||||
|
||||
### Behaviour
|
||||
|
||||
- Pointer drags fire the native `onChange`, which delegates to
|
||||
`plugin.setParameter`.
|
||||
- Keyboard events bypass the native range step (which would default to
|
||||
1 and produce mis-stepped values for parameters whose range is
|
||||
smaller or larger than 100) and run through the shared
|
||||
`resolveParameterKeyboardChange` resolver so step semantics match
|
||||
the knob exactly.
|
||||
- `Enter` is intentionally a no-op on the slider; consumers expecting
|
||||
a type-edit affordance should use `<PluginParameterKnob>`.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The native `step` attribute is `(max - min) / 100`, falling back to
|
||||
`0.0001` for degenerate `min === max` declarations. The keyboard
|
||||
handler never reads the native step.
|
||||
- The slider does not animate; pointer & keyboard interactions write
|
||||
the parameter directly and the next provider sample reads it back.
|
||||
- A `<label htmlFor>` link is used so click-to-focus on the label
|
||||
works without any JavaScript wiring.

# `<PluginSlot>`
|
||||
|
||||
Generic renderer for any `AudioFxPlugin`. Reads the plugin's
|
||||
declarative `parameters` array and renders each one through the
|
||||
primitive picked by the parameter's unit declaration. A specialised
|
||||
renderer registered through the provider's `slotRenderers` option
|
||||
supersedes the generic slot for the matching plugin id.
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<PluginSlot>` is the per-plugin face of `<PluginChainView>`. It
|
||||
turns a plugin's static declaration (metadata + parameter list + IO
|
||||
shape) into a reactive form without the consumer having to wire up
|
||||
each control by hand. The component is intentionally
|
||||
presentational — bypass, advanced-toggle, and parameter writes go
|
||||
through the same hooks any caller would use, so an EQ panel that
|
||||
wants its own visual chrome can replace the slot through the
|
||||
`slotRenderers` map without losing the keyboard / ARIA contract.
|
||||
|
||||
## Features
|
||||
|
||||
- Renders `plugin.metadata.name`, `version`, and `category` in the slot header.
|
||||
- Iterates `plugin.parameters` in declaration order.
|
||||
- Picks a knob for `unit: "db"` / `unit: "hz"` and a slider for every
|
||||
other unit (including `"percent"`, `"ms"`, `"semitones"`).
|
||||
- Exposes a bypass toggle wired to `chain.bypass(plugin.metadata.id, …)`
|
||||
when a `chain` prop is supplied; the toggle reflects the live
|
||||
bypass state via a `bypass-changed` subscription.
|
||||
- Filters parameters whose `category === "advanced"` behind a toggle
|
||||
that defaults to hidden.
|
||||
- Forwards a CSS-class API (`rax-slot`, `rax-slot__header`,
|
||||
`rax-slot__params`, `rax-slot__bypass`, `rax-slot__advanced-toggle`)
|
||||
and `data-plugin-id` / `data-plugin-category` / `data-bypassed`
|
||||
attributes for stylesheet targeting.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import { PluginSlot } from "@suaveplan/react-audio/components/plugin-slot";
|
||||
|
||||
function ChainItem({ plugin, chain }) {
|
||||
return <PluginSlot plugin={plugin} chain={chain} />;
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
// Provide a specialised EQ panel through provider options; the slot
|
||||
// will render <EQPanel/> instead of the generic form for the eq plugin.
|
||||
function App() {
|
||||
return (
|
||||
<AudioProvider
|
||||
options={{
|
||||
slotRenderers: {
|
||||
eq: EQPanel,
|
||||
},
|
||||
}}
|
||||
>
|
||||
<PluginSlot plugin={eqPlugin} chain={chain} />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Props
|
||||
|
||||
- `plugin: AudioFxPlugin` — the plugin to render.
|
||||
- `chain?: PluginChain` — when supplied, the bypass toggle is rendered
|
||||
and writes via `chain.bypass()`; without a chain there is no
|
||||
bypass surface to talk to.
|
||||
- `className?: string` — CSS class appended to the wrapper.
|
||||
- `hideAdvancedToggle?: boolean` — hide the advanced toggle even when
|
||||
advanced parameters are present.
|
||||
|
||||
### Provider integration
|
||||
|
||||
- `slotRenderers: Record<string, ComponentType<PluginSlotRendererProps>>`
|
||||
on `AudioProviderOptions` maps a plugin id to a specialised
|
||||
renderer. The generic slot consults the map first and bails to the
|
||||
registered component when present.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The bypass toggle subscribes via `chain.on("bypass-changed", …)` so
|
||||
toggles initiated elsewhere (preset apply, another panel, MIDI in
|
||||
Phase 3) propagate without a polling tick.
|
||||
- The advanced toggle is local state on the slot; it does not survive
|
||||
unmount. Persisting it would require an addition to the provider's
|
||||
UI store, which is deferred to extras.
|
||||
- The unit→control table (`db` / `hz` → knob, else slider) is
|
||||
intentionally minimal. Specialised renderers cover any remaining
|
||||
cases (segmented control for `enum`, log-curve knob, …).

# `<PremiumPlayer>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<PremiumPlayer>` is the full-featured media-player surface — a
|
||||
composition of `<AudioPlayer>`, `<AudioVisualizer>`, and
|
||||
`<MasterMeter>` arranged as a single instrument panel. It is intended
|
||||
for hero player surfaces (landing pages, profile pages, demo apps)
|
||||
that want the whole monitoring suite without forcing consumers to
|
||||
wire three components by hand.
|
||||
|
||||
Every behavioural guarantee of the underlying components applies:
|
||||
the player polls plugin state, the visualiser reads block samples
|
||||
from the named bus, and the meter computes peak / RMS / hold envelope
|
||||
on every UI tick. None of the three sub-components share state; they
|
||||
compose by sitting in the same DOM section.
|
||||
|
||||
## Features
|
||||
|
||||
- Bundles `<AudioPlayer>` + `<AudioVisualizer>` + `<MasterMeter>`.
|
||||
- Routes a single `busName` to both the visualiser and the meter so
|
||||
they show the same source.
|
||||
- Forwards `src` to the player for auto-load on mount.
|
||||
- Adds the `.rax-premium-player` class for theming.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioPlayerPlugin } from "@suaveplan/audio-fx-plugin-audio-player";
|
||||
import { AudioProvider, PremiumPlayer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new AudioPlayerPlugin({});
|
||||
|
||||
export function Hero() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<PremiumPlayer plugin={plugin} src="https://cdn/hero.wav" />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { AudioPlayerPlugin } from "@suaveplan/audio-fx-plugin-audio-player";
|
||||
import { AudioProvider, PremiumPlayer } from "@suaveplan/react-audio";
|
||||
|
||||
const plugin = new AudioPlayerPlugin({});
|
||||
|
||||
export function AuxBusPlayer() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<PremiumPlayer
|
||||
plugin={plugin}
|
||||
src="https://cdn/aux.wav"
|
||||
busName="auxA"
|
||||
className="aux-hero"
|
||||
/>
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ----------- | ------------------- | ----------- | -------------------------------------------------- |
|
||||
| `plugin` | `AudioPlayerPlugin` | — | Required. |
|
||||
| `src` | `string \| undef` | — | Forwarded to `<AudioPlayer>` for auto-load. |
|
||||
| `busName` | `string \| undef` | `"master"` | Routed to the visualiser and meter. |
|
||||
| `className` | `string \| undef` | — | Forwarded; merged with `rax-premium-player`. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The composition only forwards the `busName` to the visualiser + meter
|
||||
when one is supplied — otherwise the sub-components fall back to
|
||||
their own `"master"` defaults, which keeps the API surface honest
|
||||
about what we are choosing for the user. The player sub-component
|
||||
also receives the `src` only when it is defined, so the auto-load
|
||||
effect inside `<AudioPlayer>` doesn't run with `undefined` and trip a
|
||||
guard. There is no separate state in this component; it is pure
|
||||
composition. New monitoring sub-components (e.g. spectrum analysers,
|
||||
oscilloscope) can be added inline without changing the prop signature.

# `<PresetManager>`
|
||||
|
||||
`ChainSnapshot` save / load / delete UI layered over the provider's
|
||||
preset store. The save path persists the snapshot through
|
||||
`useChainSnapshot(chain).save(id)`, which validates against the
|
||||
`ChainSnapshotSchema` re-exported from
|
||||
`@suaveplan/audio-fx-plugin-base` and hands the serialised payload
|
||||
to the store. The load path calls `chain.restore()` through the
|
||||
hook; the delete path calls the optional `store.delete()` extension.
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
Plugin chains have a non-trivial state shape (per-slot plugin id,
|
||||
parameter values, bypass flags) and survive only as long as the
|
||||
provider stays mounted. The `<PresetManager>` gives an end-user a
|
||||
direct affordance to capture that state, name it, restore it later,
|
||||
and surface store / restore errors without crashing the surrounding
|
||||
UI. The component is intentionally chain-scoped — the same
|
||||
`<PresetManager chain={c}>` instance can sit beside any
|
||||
`<PluginChainView>` for the same chain.
|
||||
|
||||
## Features
|
||||
|
||||
- `Save` button — disabled until the name input is non-empty;
|
||||
invokes `snapshot.save(name)`, optimistically updates the local
|
||||
saved-id list, bumps an internal `version` counter so subscribed
|
||||
views re-render.
|
||||
- `Load` button — invokes `snapshot.load(id)`, which restores the
|
||||
chain order, parameters, and bypass states.
|
||||
- `Delete` button — invokes `store.delete("chain", id)` when the
|
||||
store supports the optional extension.
|
||||
- Saved-id list is fetched from `store.list("chain")` if the store
|
||||
supports it; otherwise the list reflects only the saves issued by
|
||||
the live component instance.
|
||||
- Toast surfaces every rejection with `role="status"`, the
|
||||
`AudioFxError` code (e.g.
|
||||
`AUDIO_FX.CHAIN_SLOT_NOT_FOUND`), and a dismiss button.
|
||||
- Renders an explanatory empty state when no preset store is
|
||||
configured on the provider.
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```tsx
|
||||
import { PresetManager } from "@suaveplan/react-audio/components/preset-manager";
|
||||
|
||||
function ChainSidebar({ chain }) {
|
||||
return <PresetManager chain={chain} />;
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```tsx
|
||||
// Wire a custom IndexedDB-backed preset store on the provider so
|
||||
// PresetManager can render a fully reactive saved-id list.
|
||||
function App() {
|
||||
const store = useMemo(() => createIndexedDbPresetStore(), []);
|
||||
return (
|
||||
<AudioProvider options={{ presetStore: store }}>
|
||||
<PresetManager chain={chain} className="rounded-md p-4" />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### Props
|
||||
|
||||
- `chain: PluginChain` — the chain whose snapshot is persisted.
|
||||
- `className?: string` — CSS class appended to the wrapper.
|
||||
|
||||
### Optional store extension
|
||||
|
||||
```ts
|
||||
export interface PresetStoreWithListing extends PresetStore {
|
||||
list?(kind: "plugin" | "chain"): Promise<ReadonlyArray<string>>;
|
||||
delete?(kind: "plugin" | "chain", id: string): Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
When the configured `presetStore` implements `list`, the saved-id
|
||||
list is fetched on mount and after every save / delete; when it
|
||||
implements `delete`, the Delete button is functional.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
- The save path runs `snapshot.save(id)` which itself wraps store
|
||||
rejections in `REACT_AUDIO.PRESET_STORE_FAILED`; the component
|
||||
re-surfaces the rejection in the toast.
|
||||
- The load path goes through `chain.restore(snapshot, registry)`,
|
||||
which is where `AUDIO_FX.CHAIN_SLOT_NOT_FOUND` is thrown for
|
||||
missing plugin types — exactly the error the spec scenario asserts
|
||||
the toast carries.
|
||||
- The version counter exists so any external `useChainSnapshot(chain)`
|
||||
consumer that calls `snapshot.load(...)` after a delete re-runs
|
||||
through React's effect graph rather than caching stale ids.
|
||||
- The component does not attempt to round-trip the preset on save;
|
||||
the chain's own `chain.snapshot()` is the source of truth.

# `<TrackList>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<TrackList>` is a composed-plugin UI that renders every track in the
|
||||
provider's `TimelineEngine`. It is the canonical multi-track surface
|
||||
for the React layer: each row is delegated to `<TrackRow>` so the list
|
||||
view stays small and theming concerns are isolated. The component is
|
||||
event-driven — it subscribes to the engine's typed `trackChange` event
|
||||
and updates its snapshot whenever the engine fires.
|
||||
|
||||
It is intended to drop into any layout where you want a live track
|
||||
list with no additional wiring. The "Add track" button is included as
|
||||
a convenience and can be hidden when the parent surface owns track
|
||||
creation through some richer flow.
|
||||
|
||||
## Features
|
||||
|
||||
- Subscribes to `TimelineEngine.on("trackChange")` and re-renders with
|
||||
a fresh snapshot whenever tracks are added, removed, or updated.
|
||||
- Renders an explicit "No tracks." placeholder when the engine has no
|
||||
tracks so users always see something.
|
||||
- "Add track" button delegates to `timeline.addTrack()` with default
|
||||
options.
|
||||
- Live track count badge (ARIA live region) for screen readers.
|
||||
- `role="list"` on the inner UL and `role="listitem"` on every row.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, TrackList } from "@suaveplan/react-audio";
|
||||
|
||||
export function Studio() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<TrackList />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, TrackList } from "@suaveplan/react-audio";
|
||||
|
||||
export function ReadOnlyTrackList() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<TrackList hideAddTrack className="studio-tracks" />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| --------------- | ------------------ | ------- | -------------------------------------- |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<section>`. |
|
||||
| `hideAddTrack` | `boolean \| undef` | `false` | When `true`, hides the add button. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component reads the initial snapshot synchronously on first render
|
||||
through `timeline.getState().tracks`, then mounts a `useEffect` that
|
||||
subscribes to `trackChange` and reads a fresh snapshot on every event.
|
||||
The subscription runs in a layout-safe `useEffect` and unsubscribes
|
||||
on unmount via the engine's returned `off()` handle. The "Add track"
|
||||
click handler eagerly calls `setTracks(timeline.getState().tracks)` so
|
||||
the visual list updates synchronously without waiting for the event
|
||||
loop tick. Each `<TrackRow>` re-subscribes to its own per-track event
|
||||
through `useTrack`, so removing a track from the engine collapses the
|
||||
corresponding row to a tombstone marker without unmounting the list.

# `<TrackRow>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<TrackRow>` is the per-track row primitive consumed by `<TrackList>`.
|
||||
It subscribes to a single `Track` through the foundation `useTrack`
|
||||
hook and renders the canonical row controls: editable name, mute /
|
||||
solo toggles, volume + pan sliders, and a remove button. The row
|
||||
collapses to a tombstone marker when the referenced track is removed
|
||||
so the surrounding `<ul>` does not visually re-layout in the
|
||||
intervening render frame.
|
||||
|
||||
`<TrackRow>` can also be used standalone — anywhere you have a track
|
||||
id and a provider mounted you can drop it into a list to render
|
||||
exactly one row.
|
||||
|
||||
## Features
|
||||
|
||||
- Re-renders on `trackChange` for the bound track id via `useTrack`.
|
||||
- Mute / solo as `aria-pressed` toggles with live "Mute" / "Muted"
|
||||
labels (and analogous Solo).
|
||||
- Volume slider clamped `[0, 1]` and pan slider clamped `[-1, 1]`,
|
||||
both step `0.01`. Non-numeric input is ignored.
|
||||
- Name input writes through to `timeline.updateTrack({ name })`.
|
||||
- Remove button calls `useTrack().remove()` and the row immediately
|
||||
collapses to the tombstone.
|
||||
- `hideRemove` suppresses the remove button.
|
||||
- `data-muted` / `data-soloed` attributes for theming hooks.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { TrackRow } from "@suaveplan/react-audio";
|
||||
|
||||
export function OneRow({ trackId }: { trackId: string }) {
|
||||
return (
|
||||
<ul>
|
||||
<TrackRow trackId={trackId} />
|
||||
</ul>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import { TrackRow } from "@suaveplan/react-audio";
|
||||
|
||||
export function ReadOnlyRow({ trackId }: { trackId: string }) {
|
||||
return (
|
||||
<ul>
|
||||
<TrackRow trackId={trackId} hideRemove className="row-tight" />
|
||||
</ul>
|
||||
);
|
||||
}
|
||||
```

## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| ------------- | ------------------ | ------- | ------------------------------------------------------------ |
|
||||
| `trackId` | `string` | — | Required. The id of the track to render. |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<li>` (both active and tombstone). |
|
||||
| `hideRemove` | `boolean \| undef` | `false` | Suppresses the remove button when `true`. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The active row is rendered by an inner `ActiveRow` sub-component so
|
||||
the mute / solo / volume / pan / name callbacks are only defined when
|
||||
the track exists. This keeps the hooks call sequence stable across
|
||||
the "track exists → tombstone" transition without violating the Rules
|
||||
of Hooks: the parent always calls `useTrack` first, then either
|
||||
returns the tombstone JSX (no further hooks) or renders `<ActiveRow>`
|
||||
(which calls its own bag of `useCallback`s). The tombstone collapses
|
||||
to a minimal `<li>` so list keying remains stable while the engine is
|
||||
mid-mutation.

# `<TransportControls>`
|
||||
|
||||
<!-- begin:auto-docs -->
|
||||
_(no submodules)_
|
||||
<!-- end:auto-docs -->
|
||||
|
||||
## Purpose
|
||||
|
||||
`<TransportControls>` is the composed-plugin UI for the provider-owned
|
||||
`Transport` instance. It exposes the spec-mandated play / pause / stop /
|
||||
seek / loop / tempo surface as a single accessible group of native form
|
||||
controls, mirroring the live `transport.state` and `transport.seconds`
|
||||
without requiring callers to wire `useTransport` or `useTransportTime`
|
||||
themselves.
|
||||
|
||||
The component is intentionally minimal: it is the canonical "transport
|
||||
bar" you drop into a layout and let consumers theme via the
|
||||
`.rax-transport` class. Hotkey support is opt-in for global capture but
|
||||
always available when the component itself has keyboard focus.
|
||||
|
||||
## Features
|
||||
|
||||
- Play / pause / stop buttons bound to `useTransport`.
|
||||
- Live position readout (sampled at the provider's `sampleRateHz`).
|
||||
- Tempo input writes the BPM signal at the current transport time, with
|
||||
configurable `minTempo` / `maxTempo` clamps.
|
||||
- Seek input writes positive-only second offsets, restarting the
|
||||
transport when it was playing.
|
||||
- Loop toggle drives `transport.loop` and reflects the flag.
|
||||
- Local `Space` / `Escape` / `L` hotkeys when focused, and optional
|
||||
global hotkeys via `enableGlobalHotkeys`.
|
||||
- `role="group"`, `aria-pressed`, and `aria-live` polite updates.
|
||||
|
||||
## Usage: Basic Example
|
||||
|
||||
```tsx
|
||||
import { AudioProvider, TransportControls } from "@suaveplan/react-audio";
|
||||
|
||||
export function App() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<TransportControls />
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```

## Usage: Advanced Example
|
||||
|
||||
```tsx
|
||||
import {
|
||||
AudioProvider,
|
||||
TransportControls,
|
||||
} from "@suaveplan/react-audio";
|
||||
|
||||
export function Workstation() {
|
||||
return (
|
||||
<AudioProvider>
|
||||
<TransportControls
|
||||
enableGlobalHotkeys
|
||||
minTempo={40}
|
||||
maxTempo={220}
|
||||
className="studio-transport"
|
||||
initialSeekSeconds={4.5}
|
||||
/>
|
||||
</AudioProvider>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
| Prop | Type | Default | Notes |
|
||||
| --------------------- | ------------------- | ------- | ----------------------------------------------------------- |
|
||||
| `className` | `string \| undef` | — | Forwarded to the outer `<div>`. |
|
||||
| `initialSeekSeconds` | `number \| undef` | `0` | Initial value displayed in the seek input. |
|
||||
| `minTempo` | `number \| undef` | `20` | Tempo input `min` attribute. |
|
||||
| `maxTempo` | `number \| undef` | `300` | Tempo input `max` attribute. |
|
||||
| `enableGlobalHotkeys` | `boolean \| undef` | `false` | When `true`, hotkeys fire from any `document` keydown. |
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
The component subscribes to `transport.on("start" \| "stop" \| "pause")`
|
||||
to update its local `state` and renders the play / pause button's label
|
||||
from that. The position readout is provided by `useTransportTime`,
|
||||
which samples at the provider's `sampleRateHz` budget (default 60 Hz)
|
||||
rather than per audio block — display lag of at most one frame is the
|
||||
correct ceiling for UI display. The seek handler stops and restarts the
|
||||
transport via the shared `useTransport().seek` callback to avoid races
|
||||
with the underlying tick source. Global hotkeys are registered with a
|
||||
`useEffect` cleanup so unmounting fully removes the listener; the local
|
||||
keydown handler uses `preventDefault` only for the handled keys
|
||||
(`Space`, `Escape`, `L`) so other keystrokes bubble normally.

inside `@suaveplan/react-audio`. The codes are namespaced under the
|
||||
`REACT_AUDIO.` prefix via `defineCodes` from `@suaveplan/error`, so
|
||||
consumers see stable dotted strings (`REACT_AUDIO.NO_PROVIDER`,
|
||||
`REACT_AUDIO.UNKNOWN_PARAMETER`, …) that can be matched against in
|
||||
catch-handlers or routed through an i18n message resolver.
|
||||
|
||||
Every code declared here is reachable from a real call site exercised
|
||||
by the test suite — there are no "future" codes. The pre-publish gate
|
||||
inspects `REACT_AUDIO_ERROR_METADATA` and the `REACT_AUDIO_CODES`
|
||||
object to assert the two sets agree.
|
||||
|
||||
## Features
|
||||
|
||||
- Stable dotted codes via `defineCodes("REACT_AUDIO", …)`.
|
||||
- Frozen metadata table with `description` and `severity` (`warning` or
|
||||
`error`) per code, suitable for centralised reporting or i18n.
|
||||
- `ReactAudioError extends SuaveplanError<ReactAudioErrorCode>` —
|
||||
every error thrown by the package is an instance of this class.
|
||||
- `registerReactAudioErrorCodes()` idempotent registration hook (kept
|
||||
for parity with sibling packages).
|
||||
|
||||
## Usage: Basic
|
||||
|
||||
```ts
|
||||
import {
|
||||
REACT_AUDIO_CODES,
|
||||
ReactAudioError,
|
||||
} from "@suaveplan/react-audio/error-codes";
|
||||
|
||||
try {
|
||||
// …
|
||||
} catch (error) {
|
||||
if (
|
||||
error instanceof ReactAudioError &&
|
||||
error.code === REACT_AUDIO_CODES.NO_PROVIDER
|
||||
) {
|
||||
// hook rendered without an <AudioProvider> ancestor
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Usage: Advanced
|
||||
|
||||
```ts
|
||||
import {
|
||||
REACT_AUDIO_ERROR_METADATA,
|
||||
ReactAudioError,
|
||||
type ReactAudioErrorCode,
|
||||
} from "@suaveplan/react-audio/error-codes";
|
||||
|
||||
function reportReactAudioError(err: ReactAudioError): void {
|
||||
const code = err.code as ReactAudioErrorCode;
|
||||
const meta = REACT_AUDIO_ERROR_METADATA[code];
|
||||
console.error(`[${meta.severity}] ${code} — ${meta.description}`, {
|
||||
cause: err.cause,
|
||||
context: (err as { context?: unknown }).context,
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
- `REACT_AUDIO_CODES` — frozen object whose values are the dotted code
|
||||
strings.
|
||||
- `ReactAudioErrorCode` — union of the dotted strings.
|
||||
- `REACT_AUDIO_ERROR_METADATA` — frozen
|
||||
`Record<ReactAudioErrorCode, { description, severity }>`.
|
||||
- `ReactAudioError` — class extending `SuaveplanError`; carries the
|
||||
code, an i18n `messageKey`, and optional `cause` / `context`.
|
||||
- `registerReactAudioErrorCodes()` — idempotent.
|
||||
|
||||
## Implementation Notes
|
||||
|
||||
`defineCodes` returns an object whose values are pre-formatted dotted
|
||||
strings; passing the bare literal `"REACT_AUDIO.NO_PROVIDER"` works
|
||||
equally well in `instanceof` + `code ===` checks. The metadata object
|
||||
is frozen via `Object.freeze` at module load so consumers cannot
|
||||
accidentally mutate it. `ReactAudioError`'s constructor reads the
|
||||
metadata once and writes a descriptive `name` (`ReactAudioError(error)`
|
||||
or `ReactAudioError(warning)`) so default React error overlays carry
|
||||
useful context. Every throw site in the package routes through this
|
||||
class so a single `error instanceof ReactAudioError` branch catches
|
||||
every package-originated failure.
