GarageBand FAQ: ChangeImportTempo

Q. How Can I change the Tempo/Pitch of an Mp3 (AIFF, WAV, AAC, etc) file which I've imported into Apple's GarageBand?

A. It's a very simple 2 step process.

Step 1: Turn the Orange Region into a Purple Region so that it can respond to GB's controls...

Step 2: Once the region within the track is purple, make sure the "Follow Tempo & Pitch" checkbox is selected in the track editor pane if you're using GB3 (and later). The region will then respond to the changes you make with GarageBand's controls.

NOTE: Do not expect spectacular results if you change the tempo or pitch more than a little bit. In general you're likely to get better results using an Audio Editor, though extreme changes carry the same caveat.
