m4a is basically aac, so I'd look down that route. However, m4a files 
can be protected by DRM, and those files will be much harder, maybe even 
impossible, to convert. Though, I believe the extension becomes m4p when 
protected, and also m4b when an audio book. The format is much richer 
than MP3 or WAV as it can contain meta data such as notes, images and 
chapter markers. You'll lose these when converting.
