may be what you want to ask is Audio Track vs Audio Channel, since Audio
Track n Audio Stream is the same thing.

one video file can have multiple audio track, and inside an audio track,
there is multiple audio channel with a preset configuration, be it a mono,
stereo, surround, etc.

on a video file with multiple track, each track usually have different
purpose, e.g. as a suplementary language, commentary, etc. each track can
have different configuration of channel, sampling rate, or bitrate.
