# Objective What's that? Another PR for the grand migration to required components? This time, audio! ## Solution Deprecate `AudioSourceBundle`, `AudioBundle`, and `PitchBundle`, as per the [chosen proposal](https://hackmd.io/@bevy/required_components/%2Fzxgp-zMMRUCdT7LY1ZDQwQ). However, we cannot call the component `AudioSource`, because that's what the stored asset is called. I deliberated on a few names, like `AudioHandle`, or even just `Audio`, but landed on `AudioPlayer`, since it's probably the most accurate and "nice" name for this. Open to alternatives though. --- ## Migration Guide Replace all insertions of `AudioSoucreBundle`, `AudioBundle`, and `PitchBundle` with the `AudioPlayer` component. The other components required by it will now be inserted automatically. In cases where the generics cannot be inferred, you may need to specify them explicitly. For example: ```rust commands.spawn(AudioPlayer::<AudioSource>(asset_server.load("sounds/sick_beats.ogg"))); ```
