Exporting Multitrack Projects
To export a master mix as an MP3 file:
1
Choose File > Export (or press Command-E).
The Export dialog appears.
2
Choose Master Mix from the Exported Items pop-up menu.
Note: You can also use an export preset to export a master mix. For more information
about using export presets and the Preset pop-up menu, see “
3
Choose MP3 File from the File Type pop-up menu.
The bottom portion of the Export dialog displays the MP3 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.

Choose from the following MP3 export options:
 Stereo Bit Rate pop-up menu: The higher the mono or stereo kilobits per second
(Kbps), the higher the audio quality and the larger the file size. The most common bit
rate for stereo MP3 files is between 128 Kbps and 192 Kbps. Lower bit rates are more
appropriate for sound files containing voice recordings (as opposed to music).
Some example settings and uses include:
 32 kbps: AM radio quality, suitable for medium-quality speech
 96 kbps: FM radio quality, suitable for high-quality speech or medium-quality music
 128 kbps: Suitable for good-quality music
 256 kbps and 320 kbps: Suitable for music that is near audio CD quality
 Use Variable Bit Rate Encoding (VBR): This setting varies the number of bits used to
store the music depending on the complexity of the music. This can help keep file
size to a minimum.
