Anyone know a good, free, easy to use WAV file editor for OSX? (Or an mp3 editor, I can convert it).

I’ve got this sound file I wanna post – an inadvertent voice mail – but it’s ten minutes long, with a lot of dead air. I need to chop the gaps out, and take out the bits that identify who it is. It’s a wrong number, but still.

But I can’t find anything that’s worth a damn that’s free. Such a beast has to exist. I tried ‘Wave Editor” but had nothing but trouble with it, it wrote out a horrible-sounding file and then started crashing. I don’t need anything sophisticated, just something that will let me chop out the gaps.
