Below it is played with one track (i.e. "item 1" of the song's samples') at one speed, and the other track (i.e. "item 2" of the song's 'samples') at another, slightly higher, speed. BTW - I have no idea why the song has two tracks in the first place, does anyone know?
The balance between left and right ear is changing during playback; just for fun.
Thank you @FUNTIME_FOXY101 for the inspiration and don't be afraid to show your projects in Share your Projects category, next time.
Some sounds have one channel (mono) and other sounds have two channels (stereo). I think one channel (track) is for the left side and the other for the right side.
