Bevy audio systems

When to use

Load this when a clip should start, loop, pause, or change volume. bevy::audio on docs.rs latest (0.20.0) and the audio_control example there are the sources.

ECS shape

Play: spawn AudioPlayer::new(asset_server.load(...)). AudioPlayer<Source> holds Handle<Source> where Source: Asset + Decodable. If the asset is not ready, playback starts when it is. AudioPlayer requires PlaybackSettings.
Settings: PlaybackSettings configures the start. PlaybackSettings::LOOP and .with_spatial(true) appear in the spatial examples. Changes to PlaybackSettings do not affect audio that is already playing. PlaybackMode is Once, Loop, Despawn, or Remove.
Control: when playback begins, Bevy inserts AudioSink. The control example queries AudioSink and calls pause, toggle_mute, set_volume, set_speed, and position. SpatialAudioSink is the spatial counterpart named on the playback page.
Replay: after a non-looping sound finishes and the sink is drained, that AudioPlayer cannot be reused. Remove the audio components and add them again.
Schedule: spawn on Startup or from a system that has Res<AssetServer> and Commands. Control systems in the example run where they read ButtonInput<KeyCode> and Res<Time>.

Coming from Godot

Godot idea	Bevy idiom
Play a file	`AudioPlayer::new` plus `AssetServer::load`
Loop	`PlaybackSettings::LOOP`
Pause / mute / volume while playing	`AudioSink` methods on the same entity
One-shot that should leave the world	`PlaybackMode::Despawn` or `Remove`
Positional emitter	`PlaybackSettings` with `with_spatial(true)` and `SpatialAudioSink`

Scope

Check the audio docs for bus graphs, music/sfx mixer layouts, and audio-area shapes before writing them.
Check the audio docs for sample rates, supported file types, and the AudioSource type beyond the Handle in AudioPlayer::new.
Removing AudioSink restarts an attached source (stated on the sink page). Check that page for a full restart recipe before writing one.

Expert Knowledge Delta

Target: Bevy 0.20+.

Core ECS types: Component, Resource, Query, Commands, Startup, Update, Fixed / FixedMain (bevy::time), .chain(), Plugin, DefaultPlugins, MinimalPlugins. Messages and observers are an ownership slot. See bevy-events-messaging for their APIs. Systems run in parallel unless .chain() orders the ones that conflict.

Who owns state

Piece	Owner	Who may mutate	Schedule
Data on one entity	`Component`	One system via `Query`	`Update` or `FixedMain`
One value for the whole app	`Resource`	One system	`Startup` to insert, then the schedule that reads it
Spawn	`Commands`	The spawning system	`Startup` for the initial world; later schedules for runtime spawn
Order that must not race	`.chain()`	The chained systems only	Same schedule
Plugin boundary	`Plugin`	`build` registers systems and resources	Before the app runs

Borrow rule: two systems that both mutably query the same component must be ordered (.chain()) or split so only one writes. Unrelated systems stay parallel. That is the ECS page rule, not a guess at a system-set API.

Decision

If you need	Do this	Do not
Per-entity data	`Component` + `Query`	A Godot node script
App-wide config or clock	`Resource`	Copy the value onto every entity
Stable simulation step	`FixedMain` and the `Fixed` clock	Tie simulation to raw frame `Update`
Startup spawn	`Commands` in `Startup`	Spawn from a render system
Cross-system notice that is not shared state	Message or observer slot in `bevy-events-messaging`	A new event type invented in this file
An API outside the documented set	Check the official docs first	A made-up crate or API

Load references/ecs-ownership.md for the ownership table.

NEVER

Do not pin /0.20.0/ in docs URLs. WHY: links stay on latest; the 0.20 target is stated once in prose.
Do not mutably query the same component from two unordered systems. WHY: the schedule runs systems in parallel unless .chain() orders them.
Do not invent a physics, navigation, networking, or XR crate here. WHY: this skill only names documented Bevy crates and modules.

No Godot audio player, bus, or stream types. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.
No volume curves or mixer nodes this file did not open. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.
No third-party audio crates. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.

Reference

docs.rs links use the unversioned latest permalink. The library pin on bevy-master stays 0.20.0.
