I'm looking for an app (cheap or free) that will change the tempo of an audio track without changing pitch. I've tried Amazing Slow Downer from ronimusic.com. It works great, but is a little pricey at $45. Anything else out there? I'm not looking to save the changes, or use the altered file in anyway other than to slow down fast passages and play along. I guess I'm trying to use it as a transcriber or practice companion (actually, I'm trying to find something for my studentsthe ones that use Macs, anyway). any help, much appreciated.
