Chapter 8 Basic Mixing in Soundtrack Pro 267
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.)
In this case, the left and right channels for each submix are routed to the left and right
(1 and 2) channels of the hardware output device. All three submixes are combined
into one stereo (left and right) signal. This is a “stereo mixdown,” suitable for any
stereo-capable playback device. At this stage, the Master bus presents a (final)
opportunity to make volume adjustments and apply effects. For information about the
Master bus, see “
Using the Master Bus ” on page 290.
