Does anyone know how to change the tempo of an audio file to match a new tempo map. Example: say you recorded a track at 100bpm but now you have created tempo changes and you don't want to rerecord it. Is there a way by which you can just tell logic to line up the track to the new tempo map?

Have you tried converting your audio to AppleLoops format? You can use the Apple Loops Utility to create an AppleLoops version of your file.
