Apple Soundtrack Pro 3 - Manual (Page 310)

The following diagram shows how audio signals from tracks in each category are routed
into their respective submixes.

Once the audio signals are organized in this way, you can apply (and automate) volume
settings and effects on any of the submixes, rather than on the individual tracks or busses.
You might, for example, add a compressor or EQ effect to a Dialogue submix to enhance
all of the dialogue signals at once. Obviously, this saves a lot of time and effort (when
compared with applying all of these settings to each dialogue track individually). Using
submixes to segment your project provides you with greater control over all aspects of
your final mix.
Creating a Stereo Mix
The next routing decision is the choice of hardware outputs. The following example
diagram shows the routing for a traditional final product: a stereo mix. To do this, you
would simply choose the Stereo 1,2 output for each of the three submixes. (This also
happens to be the default output for every submix in Soundtrack Pro.)
