M4B Audio Format M4B Converter
The M4B audiobook format was developed by Apple, and the format is also known as an MPEG-4 Audio Book file. M4B files are mostly used for the audio part of the Apple Books application, which is included as standard on iOS and macOS. If you buy an audiobook from the Apple Books store, the downloads are normally in M4B format and are DRM-protected to prevent sharing.
M4B files are containers for both audio and metadata. The audio part of an M4B file is in MPEG-4 format and compressed with AAC encoding to make the file smaller. AAC is the same standard format that Apple uses for digital music in iTunes. M4B is also very similar to Apple’s M4A audio format for podcasts and music; however, because M4B is designed for audiobooks, it supports bookmarks and breaks for each chapter. You can open M4B files with Apple Books, iTunes, VLC and some audiobook players.

M4A Audio Format M4A Converter
M4A files are an extension of the MP4 container format (MPEG-4 or Moving Picture Experts Group-4). Originally developed by Apple as a competing format to MP3, M4As are specifically used to store audio-only material such as podcasts, music, audiobooks and other auditory entertainment. You can open these files using Apple Music, VideoLAN VLC media player, Microsoft Windows Media Player and others.
M4A files are typically encoded with ALAC (Apple Lossless Audio Codec) or AAC (Advanced Audio Coding), compressing the files to produce smaller file sizes that retain high-quality sound. Due to their reduced file sizes, M4A files are a go-to format for sharing and downloading audio content, especially music downloaded from the Apple iTunes Store. You can play M4A files with most popular media players, including Apple Music, Apple Quicktime, Windows Media Player (if you add the K-Lite Codec Pack), Adobe Audition, and VLC.
