Before we show you how to convert M4B to MP3, it is better to know more details on the M4B audiobook format so that you can adjust the encoding settings much more wisely.

What is M4B format?

A file with the M4B file extension is a MPEG-4 Audio Book file. The .M4B extension is specially designed for labeling audiobooks purchased from Apple's iTunes Store. And it is almost identical to the M4A extension because both formats use the MPEG-4 Part 14 container format (commonly known as MP4).

When it comes to audio compression, the audio in an M4B file is encoded with the AAC compression format. Also, before Jan. 6th, 2009, much similar to other media content purchased from iTunes, the M4B audiobooks are protected with Apple's FairPlay DRM copy protection system.
