Exporting a Master Mix
A master mix (or project mixdown) is a single audio file that contains all of the elements
and settings in your multitrack project. When you export a master mix, all unmuted tracks,
busses, and submixes that are routed to hardware output jacks are included in the
exported file. You can exclude any tracks, busses, and submixes from the exported mix
by muting them. For more information about routing to hardware output jacks, see
Setting Hardware Outputs and Setting the Submix Outputs to Surround .
Setting Submix Outputs
By default, all submix outputs in Soundtrack Pro are set to Surround 1-6. This setting
affects how audio signals are routed and how files are exported from multitrack projects.
Use the Output pop-up menu in each submix to choose an output channel or set of
output channels. Your choice defines the output of that submix (and any files exported
from that submix) as either mono, stereo, or surround.
If you export a master mix using multiple submixes, the output channel or set of output
channels of the first submix defines the channels used for the output of the exported file
as either mono, stereo, or surround.
Exporting a Master Mix to a Standard Audio File
You can export a mixdown of your project to any of the following standard (uncompressed)
audio formats: AIFF, WAVE, NeXT, and SoundDesigner II.
To export a master mix as a standard audio file
1 Choose File > Export (or press Command-E).
The Export dialog appears.
2 If you want, choose an export preset to export a master mix from the Preset pop-up
menu.
