Freeware to change audible.com purchased book to mp3 for the clip

Unfortunately, as I mentioned above, if iTunes has the Audible files in the .aac format (and not the .aa format that results on PCs), I think you’re out of luck there–the Clip+ does not play .aac files (only the newest Clip, the Clip Zip, does). Now, if you had a way to get the files in the .aa format (not .aac), such as through the use of the Audible Manager on a PC, you wouldn’t have this issue on the Clip+.
