Audio getting progressively worse. (By default)

What you did

I searched up how to play a sound in bevy, and used this code from a bevy example to play some mp3 files for my pong clone.
https://github.com/bevyengine/bevy/blob/main/examples/audio/audio.rs
commands.spawn(AudioBundle { source: asset_server.load("sounds/Windless Slopes.ogg"), ..default() });

What went wrong

Every time a sound plays, the audio quality gets worse. At 100 sounds played, it is unrecognisable. I have a video here to show it more clearly:

I believe the audio entities by default don't get despawned. You can change the behavior to PlaybackMode::Despawn on the audio bundle https://docs.rs/bevy/latest/bevy/audio/enum.PlaybackMode.html

I have already tried that. Here is the full code:

Nevermind, I hadn't set it in every instance that I spawned an AudioBundle. May I ask why it isn't Despawn by default?

I think it's not the default because it creates very undesirable behavior when an AudioBundle is attached to a normal entity with other data (i.e. it causes the entire entity to be destroyed when audio stops playing). (However, the default right now is also just very bad.)

[redstonerti]

It's possible that spawning audio as a component is not a good idea. Wouldn't it be better if it was a resource that could be accessed from anywhere, like Commands or something?

Maybe something like this?

AudioManager.play(source_file, AudioSettings{volume, pitch, Mode::Spatial3D(x,y,z)});

Although now that I think about it, it is really convenient how it is right now, because you can spawn AudioBundles along with enities and they can access and play them whenever they want, without having to necessarily know what they are playing. I could be picking up a rock or a stick for example, and they could be playing different audio with the same code, just by being spawned differently

How would you do spatial audio with a resource?

I have no idea and no experience. I was just typing what I was thinking. Forget the spatial audio, I just thought it could be simpler to use a resource to play sounds.

#12359 is much clearer to track: I'm going to close this out in favor of that issue.
