Wave Editor For Mac

A friend of mine is asking on a forum I use what a good wave editor is for the Apple Mac. Comes from Sound Forge on the PC (also my favourite) but that isn’t available on the Mac and neither is Wavelab from what I hear (quite surprised at both of those as big products.)

Can some of you lovely Mac users recommend some software, think preferably free or cheaper side of things but he will consider all. Obviously something like Logic is going to be massive overkill for him! So far know Audacity and Adobe Audition but don’t particularly like either of them.

I use Amadeus Pro:

Cheers guys, passed both those links on :)
