iTunes runs the greatest amount of media contents, including videos, music, and audiobooks, as well as useful apps. To be honest, it successfully shapes our life to a large extent with all these valuable resources. However, it is a pity that most of iTunes resources can only be available on Apple devices, for example, iTunes audiobooks, which are usually encrypted in M4B format, cannot work as flexibly as M4A files. This truly brings some compatibility issue to non-Apple system or devices. Fortunately, many apps are developed to tackle the format compatibility issue so if you are wondering how to convert iTunes M4B audiobook to M4A, follow the below post and you will get two simple ways to achieve that.

Part 1. M4B vs M4A

Don’t you ever feel puzzled by these two similar formats? Certainly so but never mind, I will go through their definitions for you. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files. This format is universally compatible and is one of the most widely used audio formats in the world. On the other hand, M4B is a file extension for an MPEG-4 part 14 audio layer audio book container file format used by iTunes. An M4B file is very similar to an M4A file and iTunes identifies audiobook files versus music files by the name suffix “.M4B,” but other than that the files are very similar to the .M4A format for standard audio. Another big difference for M4A VS M4B lies in DRM, a FairPlay scheme for iTunes media contents. Usually, M4B is far less popular than M4A due to DRM so we often remove DRM from iTunes M4B audiobook and convert M4B to M4A for better use in non-Apple devices.
