Audio Tracks
Signal flow begins in the Timeline, where you can have up to 99 audio tracks. Audio tracks
contain audio clip items from clips that you have edited into your sequence. The signal
from each audio track can be routed to an output bus, and multiple audio tracks can be
assigned to the same bus.

Busses
A track is connected to a bus. A bus allows you to mix multiple audio tracks into a single
signal. An output bus is typically connected to a hardware audio output on your computer
or audio interface. Without busses, only one track could be connected to a physical audio
output at a time, requiring you to have as many physical audio outputs as you had tracks.
For example, if you have a sequence with eight audio tracks, you can assign the output
of each track to the same bus. That bus mixes the eight audio signals together and sends
the combined signal to a hardware audio output so you can hear all eight tracks on a
single speaker.
Each bus typically corresponds to a hardware output, so busses and hardware outputs
are usually synonymous. However, you can also use output busses to group track outputs
together for mixing and grouped export. Busses can be mono or stereo and can be
connected to one or two hardware outputs, respectively.
