Audio

Bevy offers a (somewhat barebones, but still useful) ECS-based Audio framework. This chapter will teach you how to use it.

You can play sound effects and music from your game, with volume control. There is a rudimentary "spatial audio" implementation, which can pan sounds left/right in stereo, based on the transforms of entities. You can also implement your own custom sources of audio data, if you want to synthesize sound from code, stream data from somewhere, or any other custom use case.

There are also 3rd-party alternatives to Bevy's audio support:

• bevy_kira_audio: uses kira; provides a richer set of features and playback controls
• bevy_oddio: uses oddio; seems to offer more advanced 3D spatial sound
• bevy_fundsp: uses fundsp; for advanced sound synthesis and effects

(Bevy's official audio is based on the rodio library.)

As you can see, the Rust audio ecosystem is quite fragmented. There are many backend libraries, all offering a different mix of features, none of them particularly exhaustive. All of them are somewhat immature. You have to pick your poison.

Audio is an area sorely in need of improvement. If you are an enthusiastic audio developer, consider joining Discord and helping with development!
