I did not choose the format, I'm just dealing with its consequences! IIRC I considered audacity for this same situation with mp3s and ended up not using it because it had to re-encode MP3 files resulting in quality loss.
Maybe I'll just use a stream recorder or audacity on them and then just move forward with the resulting mp3. I don't think I'll notice the quality loss on audiobooks much anyway. I mean, they're already in 32kbps WMA so they probably sound about as shitty as they can get to begin with.
