You have several audiobooks which were purchased from iTunes and you would like to listen to them on your MP3 player, in your car or other more portable devices. But only to find that these m4b files can not be transferred from iTunes media to your MP3 player or USB storage device. So how can you make the audiobooks recognized by your players or devices?

Convert iTunes M4B Audiobooks to MP3

M4B is a kind of file extension of a MPEG-4 audiobook file. This file container is often used by iTunes to store audio books. And M4B files support metadata for chapters and bookmarking on supporting players and most commonly uses AAC as audio codec.

You are allowed to rename the extension from .M4B to .M4A, thus you can play it on Windows Media Player, or you can use VLC or iTunes to convert M4B audiobooks to MP3, but these only work for unprotected audiobooks. However, the M4B audiobook you purchased from iTunes is protected, which means that you can only play it by using the authorized computer software like iTunes, and Apple devices. To make your iTunes M4B audiobooks can be successfully recognized by other more devices or audio players, you need to convert these M4B audiobooks to ordinary audio format like MP3 by using an audiobook converter.
