as the AudioFile library can handle an arbitrary number of channels and it has been added to serve as ane example for multichannel files.

The provided wav file is an 8-channel wav with different detuned oscillators that are amplitude-modulated by LFOs at different rates. Each oscillator is assigned to a different channel.

If WALK_CHANNELS is defined then channels on the file will be played one by one independenty for each playback cycle.
