Sounds can have different numbers of channels, and those channels can map to various speaker layouts.
|stereo||2 channels. The first channel is for the left speaker and the second is for the right.|
|ambisonic||4 channels. Ambisonic channels don't map directly to speakers but instead represent directions in 3D space, sort of like the images of a skybox. Currently, ambisonic sounds can only be loaded, not played.|
