Bevy Kira audio

This bevy plugin is intended to try integrating Kira into Bevy. The end goal would be to replace or update bevy_audio, if Kira turns out to be a good approach. Currently, this plugin can play .ogg, .mp3, .flac, and .wav formats and supports web builds for everything except for mp3.

I am using Oicana as "guinea pig project" and will keep it's game audio plugin up to date with this crate. You can also check out the examples directory in this repository for a display of this plugin's functionality.

Usage

To initialize the corresponding AssetLoaders, use at least one of the features ogg, mp3, wav, or flac. The following example assumes that bevy_kira_audio/ogg is used.

use bevy_kira_audio::{Audio, AudioPlugin};

// in your game's AppBuilder:
// app.add_plugin(AudioPlugin)

fn my_audio_system(
    asset_server: Res<AssetServer>,
    audio: Res<Audio>,
) {
    let music_handle = asset_server.get_handle("sounds/music.ogg");
    audio.play(music_handle);
}

Current state

• play common audio formats
  • ogg
  • mp3
  • wav
  • flac
• web support
  • The features ogg, flac and wav can be build for WASM. There are some differences between browsers:
    • Firefox: The audio might sound distorted (trying to figure out why)
    • Chrome: an interaction with the website is required before the AudioContext is started (e.g. a button click). Currently, the plugin cannot restart the AudioContext after an interaction.
• pause/resume and stop tracks
• play a track on repeat
• control volume
• control pitch
• control panning
• get the current status of a track (time elapsed/left)?
