6 In the Sound Settings dialog, choose the format, number of channels, sample rate,
quality, and sample size (bit depth), then click OK.
Important: Avoid audio compression unless you are specifically required to use it for
multimedia projects or the web.
7 When you’re ready to export, click Save.
The name of the exported audio file defaults to the name of the sequence. If you are
exporting multiple audio tracks this way, you need to manually name each audio file
with the corresponding track number before you save it.
Exporting Audio Output Groups to AIFF Files
The Export Audio to AIFF(s) command exports an AIFF audio file for each output
channel group in your sequence. The number of audio files exported is based on the
number of mono and stereo output channels assigned to your sequence. You can set
the number of audio outputs in the Audio Outputs tab of the Sequence Settings
window. Dual mono channels are exported to two mono audio files, and a stereo
channel is exported to a single stereo audio file.
One of the primary uses of the Export Audio to AIFF(s) option is to maintain the
separation between audio tracks during export. For example, your entire 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.
