Before embarking on the conversion process, it's beneficial to have a basic understanding of both M4B and AAC file formats. M4B files, typically associated with audiobooks and podcasts from Apple's iTunes platform, are known for their bookmarking feature, which is handy for resuming playback from the last stopping point. However, M4B's compatibility is relatively limited across various devices and media players. AAC (Advanced Audio Coding), on the other hand, is a more widely accepted audio format. Known for its improved sound quality over MP3, AAC files are universally supported across a broad range of devices and software.
The primary advantage of converting M4B to AAC is the universal playability of AAC files. Whether it's for ensuring your audiobooks are playable on non-Apple devices or for broader compatibility with various media players and audio software, converting to AAC is a practical solution.

What is AAC?
Full name
Advanced Audio Coding
Format type
Audio
Developed by
Fraunhofer, Dolby, Sony, and others
Description
AAC, which stands for Advanced Audio Coding, is a widely used format for audio compression and the most common audio format for Apple devices. The AAC file type was created as a substitute for MP3. Generally, AAC provides better sound quality than MP3 at similar bitrates. Many devices, including Apple and Android, support AAC. But if you want to play your audio collection on another device without iTunes, your best option is to change the format of your files to MP3, which is still used almost everywhere. Check the list below if you’re not sure how to open AAC audio files and which programs support playback of these files.
File extension
.aac, .m4a, .m4p, .m4b, .mp4, .3gp
Technical details
Files with the AAC specifications enable temporal noise shaping, non-uniform sampling, and bitstream reformatting for 16 stereo, 16 mono, 16 low-frequency channels, and 16 annotation channels in a single bitstream. In 1999, the AAC format was included in the MPEG-4 Part 3 format, after which AAC added support for audio object types and permanent noise replacement technology. AAC is currently described in the ISO / IEC 14496-3 standard.
