flutter-soloud-mixing-busTeaches flutter_soloud mixing buses for routing groups of sounds through shared sub-mixes with collective volume and filters, such as separate music, SFX and UI sliders.
A Bus is a virtual mixer channel: sounds routed through it share one volume and one set of filters. The skill covers creating a bus with `SoLoud.instance.createMixingBus`, looking buses up through the `Buses()` registry, playing the bus itself on the engine with `playOnEngine` and then playing sounds onto it, either with the bus's own play methods or by passing a `busId` to `SoLoud.instance.play`. Bus id 0 always means the main engine output.
It also covers moving a live sound onto a bus with `annexSound`, scoping filters to one bus through `bus.filters` and setting the channel count with `setChannels`. There is no `bus.volume` property, so bus volume is changed through the SoLoud volume functions on the bus's sound handle. The skill contrasts this explicit routing with players that use one player per sound and have no sub-mix concept, and `references/api.md` holds the API details. The excerpt ends within the API list.

flutter_soloud Mixing Buses loads about 1.7k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 678 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.

volume change or one filter affects everything on the bus. The canonical use
is separate Music / SFX / UI buses behind user volume sliders. Unlike
audioplayers/just_audio (one player per sound, no sub-mix concept), routing is
explicit: you create a bus, play the bus itself on the engine, then play
sounds onto it.
import 'package:flutter_soloud/flutter_soloud.dart';
Future<void> main() async {
await SoLoud.instance.init();
// 1. Create the bus (synchronous, cheap).
final sfxBus = SoLoud.instance.createMixingBus(name: 'SFX');
// 2. REQUIRED: play the bus on the engine. Until this call, the bus
// (and everything routed through it) is silent.
sfxBus.playOnEngine();
// 3. Route sounds through the bus.
final explosion = await SoLoud.instance.loadAsset('assets/explosion.mp3');
sfxBus.play(explosion); // synchronous, returns SoundHandle
// 4. Collective volume: set it on the bus's own handle, not per-sound.
SoLoud.instance.setVolume(sfxBus.soundHandle!, 0.5);
// 5. Shared filter on everything routed through the bus.
sfxBus.filters.echoFilter.activate();
// Cleanup: stops all sounds playing through the bus.
sfxBus.dispose();
}SoLoud.instance.createMixingBus({String name = ''}) → Bus. Synchronous;
registers the bus in the Buses() registry. First bus gets busId == 1;
busId == 0 always means "the main engine output".Buses() singleton registry: Buses().buses (list of all live buses),
Buses().byName('SFX'), Buses().byId(1). Both lookups throw if not found
unless you pass orElse.bus.playOnEngine({double volume = 1.0, bool paused = false}) →
SoundHandle. Makes the bus audible; stores the handle in
bus.soundHandle. Calling it again on the same bus stops the earlier
instance (only one bus voice at a time).bus.play(sound, {volume, pan, paused, looping, ...}) and its siblings
bus.playClocked, bus.playScheduled, bus.play3d, bus.play3dClocked,
bus.play3dScheduled — thin wrappers that forward to the SoLoud method
of the same name with busId set.SoLoud.instance.play(sound, busId: sfxBus.busId) — every SoLoud
play method takes an int busId = 0 parameter.bus.annexSound(handle) — re-parent a live voice (by its SoundHandle)
into this bus, e.g. move a sound already playing on the engine onto a
filtered bus mid-playback.bus.volume property. Use
SoLoud.instance.setVolume(bus.soundHandle!, v) /
SoLoud.instance.getVolume(bus.soundHandle!). This scales every voice
routed through the bus on top of each voice's own volume.bus.filters — a FiltersSingle scoped to this bus; filters activated
here apply to all routed sounds only (engine-wide filters live on
SoLoud.instance.filters). See skill flutter-soloud-filters.bus.setChannels({Channels channels = Channels.stereo}) — bus output
channel count (Channels.mono/stereo/quad/surround51/dolby71).bus.getChannelVolume(channel) — approximate per-channel output level for
VU meters. Requires SoLoud.instance.setVisualizationEnabled(true) first;
returns 0 for out-of-range channels.bus.getActiveVoiceCount() — voices currently playing through the bus;
returns 0 if the bus isn't playing on the engine.bus.isActive — true once playOnEngine() succeeded.bus.dispose() — destroys the bus and stops all sounds routed through
it; removes it from Buses().Everything above (except createMixingBus lookups and dispose) is
synchronous and returns SoundHandle directly — do not await them.
playOnEngine() is the #1 failure. Sounds
"play" (handles are created, voices count up) but nothing is heard.
bus.soundHandle stays null until then, so guard with
if (bus.soundHandle != null) before volume/filter-parameter calls.bus.volume / bus.setVolume(): they don't exist.
Volume goes through SoLoud.instance.setVolume(bus.soundHandle!, v).
Models coming from audioplayers habitually look for a per-player volume
setter — route them to the bus handle instead.await on bus play methods: bus.play(...) returns SoundHandle,
not a Future. SoLoud.instance.loadAsset is the async part; playback is
synchronous.Bus method throws
SoLoudBusDisposedDartException after dispose(). Double-dispose also
throws — null out your reference after disposing.await SoLoud.instance.init(): the constructor calls
into the native engine, and playOnEngine() throws
SoLoudBackendNotInitedException when the engine isn't up.byName/byId throw when missing: they use firstWhere; pass
orElse or check Buses().buses first if the bus may not exist.SoLoud.instance.setMaxActiveVoiceCount). Hitting
it is not an error — the new sound just doesn't play.annexSound needs a live handle: annexing a finished/invalid handle is
a no-op on the native side; check sound.handles / isActive first.bus.filters.pitchShiftFilter.shift(soundHandle: bus.soundHandle).value = 2.5;
after activate(). Plain .shift.value targets the global filter, not the
bus voice.references/api.md — full signatures of all six bus play variants, the
Buses registry, exceptions, and the AudioManager (music/SFX/voice +
