.M4B File and How to Open .M4B File?

M4B is a type of audio file that uses the MPEG-4 container format, which is the same format used for .MP4 video files. M4B files are typically used for audio books and podcasts, and unlike the more popular MP3 format, M4B files support “bookmarking” which allows users to resume playback at the same point where it was last stopped.

To open, play, and edit M4B files, you will need a media player or editor that supports the MPEG-4 container format, such as iTunes, VLC, or QuickTime. If you are using iTunes, you can open the M4B file by double-clicking it; this will add the file to your library and begin playback. If you are using VLC, you can open the M4B file by clicking File > Open File and then selecting the M4B file. In QuickTime, you can open the M4B file by clicking File > Open File and then selecting the M4B file.

If you want to edit an M4B file, you will need a more advanced media editor such as Adobe Audition or Audacity. Both of these programs support the MPEG-4 container format, so you can open and edit M4B files as you would any other audio file.

M4B files are becoming increasingly popular for audio books and podcasts, as they provide an easy way to keep track of where you left off. While the M4B format is not as widely supported as the MP3 format, there are still plenty of programs that can open, play, and edit M4B files.
