Addenda to my previous post and to bikefridaywalter's post:
Swithch works well in my Intel-based Mac, but it takes soooooooooo loooooooooong to launch...
Two years after Apple switched to Intel processors, I wonder why some developers still release PowerPC (only) applications. I did not buy the Plus version of Switch because it does not run natively in Intel Macs.
And this same developer has just released a new version of their audio editor, Wavepad, and it is once again a PowerPC application. It also takes "ages" to launch and the interface doesn't even remotely look like a Mac app.
Well... I hope it won't take two more years until they realize that it's time to release Universal Binary versions of their software.

only thing that reliably handles wma's but i don't really like it otherwise.

Although this a PowerPC application, the new version (1.12) works very well in my Intel-based iMac, running Max OS X Tiger (10.4.10).
To covert audio files to MP3 or WAV, the free version is enough. To convert to other formats, you'll have to buy the Plus version (about $20).

Nice, straightforward app, but this thing just hung around even after "quitting" it. Activity Monitor said otherwise, and was still using 99% CPU processes. Would like to find something similar that is less of a resource hog.

I actually switched to this from iTunes LAME after the latter had started bugging my system badly. I find it perfect for converting AAC files into mp3s.
