3 Choose AAC/Podcast File from the File Type pop-up menu.
The bottom portion of the Export dialog displays the AAC/Podcast export options. Since
Soundtrack Pro can tap the power of Compressor as a background process, these export
options are identical to the corresponding options in the Compressor application.
The AAC/Podcast export options are divided into three separate panes: Audio,
Streaming, and Podcast.
4 Choose from the following export options in the Audio pane:
 Channels pop-up menu: Choose either mono or stereo for the exported media file.
 Sample Rate pop-up menu: Choose from one of the following sample rates:
8, 11.025, 12, 16, 22.050, 24, 32, 44.1, or 48 kHz. You can also choose Recommended to
have Soundtrack Pro automatically choose a sample rate that is suitable for the
Channels and Bit Rate settings.
 Quality pop-up menu: Choose one of the following for the audio quality of your
output media file:
 Low: This allows for fast transcoding, but at the expense of output file quality.
 Medium: The audio quality is better than Low, but this takes longer to transcode.
 High: This is the best audio quality setting available. Use this setting when the
audio quality is important for the output media file and you don’t mind how long
it takes to transcode.
 Bit Rate slider and field: Move the slider to set the overall audio bit rate for an
exported media file between the range of 16 Kbps (2 KB/sec.) to 256 Kbps (32 KB/
sec.), or enter a specific number in the accompanying field.
