How to Save to MP3 - Strange

I already have it saved as a project and it's edited. Can I somehow change it now as you suggested?

I'm confused.

The documentation for Soundtrack Pro 3 says I can export as an MP3. Here is a copy of the manual:

To export a master mix as an MP3 file
Choose File > Export (or press Command-E).

The Export dialog appears.

If you want, choose an export preset from the Preset pop-up menu.

For more information, see “Using Export Presets.”

Choose Master Mix from the Exported Items pop-up menu.

Choose MP3 File from the File Type pop-up menu.

The bottom portion of the Export dialog displays the MP3 export options. Because 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.


Specify additional MP3 export options.

For more information, see “About MP3 Export Options.”

If you like, use the After Export pop-up menu to choose a post-export action.

For more information, see “Using Post-Export Actions.”

Enter a name for the exported file, then navigate to the location where you want to save the file.

Click Export.


I have opened this is the multi track view. It's in WAV and is edited and ready to export - but the export feature is greyed out.

Any ideas?

Thank you - that is what I was missing. It is exporting but it exports an mp3 painfully slow. LOL

But it's working.

Thanks to everyone.

Hey David - thanks.

How would I user compressor directly?

Once I have the file edited as a WAV or AIFF, do I need to drag it back in to Soundtrack or somehow go to compressor in another way?

Wow, what an education. 🙂

I'm surprised with MP3 being such a standard that it's not FAR better supported. Weird.

David thanks. I processed a 45 min, WAV file to MP3 using compressor and you're right, it was FAST.

Thanks to everyone who responded. I'm grateful.
