Chapter 11 Exporting Audio for Mixing in Other Applications 153
II
Here’s a typical example illustrating how you might export multichannel audio from an
edited sequence. Suppose you’ve set up a sequence to have three stereo audio outputs
and 12 audio tracks.
The Audio Outputs tab of the Sequence Settings window would look like this:
And the sequence would look something like this:
Each of the 12 audio tracks can be assigned to one of the three pairs of output
channels. More than one track can be assigned to the same output channel, in which
case the audio from those tracks is mixed to a single audio file during export.
One of the primary uses of the Export Audio to AIFF(s) option is to maintain the
separation between audio tracks during export. In the above example, the entire edited
sequence may have already been mixed to a final stereo audio file, but you can also
export each track grouping to a separate AIFF file, so that foreign distributors can
redub the dialogue into another language separately, without affecting the music,
background audio, and sound effects.
