Part 3. What is the difference between M4B and M4A

M4B files are generally audiobooks and are divided into two major categories. While one category includes DRM protected iTunes audiobooks, the other one includes decrypted audible AAX books. The audio of an M4B file is encoded with the AAC compression code and is generally protected by Apple’s Fairplay DRM copy since most of these files are purchased through Apple’s iTunes store.

This encryption or protection is done by Apple to restrict access to the audio files and ensure that only computers and iOS devices with authorization through iTunes can access the files. M4A files are quite similar to M4B files, with the prime difference being better accessibility, and the M4A files are used for music instead of audiobooks. For better accessibility and support across multiple platforms, you need to convert M4B to M4A audio files.


M4B audio files are quite similar to M4A format files. These files are usually encoded with the AAC codec. M4B files primarily comprise the audiobooks on platforms like iTunes, and the file format supports chapters and bookmarking. M4A audio file format, on the other hand, is very similar to MP4.

If you are looking to convert M4B to M4A files seamlessly, Wondershare UniConverter is the choice you must make. It is easy to use, efficient, fast, and ensures high-quality conversions.
