MP3/WAV Editor?

Can anyone recommend a good, simple (free) audio editing program for a Mac? I used to use CDwav on my PC. All I need to do is make a tune a minute shorter on the front end and about 2 minutes shorter at the end. Nothing fancy.

here is a list http://www.apple.com/downloads/macosx/audio/
