Audible Format
Podunk said:
I'm pretty sure that theres no know way to do it. I've been trying to figure the same thing for a long time.
I pretty much just gave up and now I just buy all my audiobooks from Audible. But I do have a few oldies that I'd still like to convert somehow.
Good news, it is Possible.
But, it's really long winded..
Firstly take your Audiobook MP3 files and merge them into a few BIG Mp3's.. Best to keep the size <100Meg or so.
Next import the file into iTunes and convert them into AAC (not too high quality to save space)
When it's done, and this is the clever bit, delete both entries, but don't move them to the recycle bin..
Find the orignal MP3 files and delete them, also the merged mp3 files...
Next, find the m4a file and change it to a m4b file.
Job Done!
