Convert M4B to M3U

Understanding m4b and m3u file formats

M4B is an audiobook file format based on the MPEG-4 Part 14 standard, commonly used for storing audio books with support for chapters, bookmarks, and metadata. These files are typically used by Apple devices and applications like iTunes and Apple Books.

M3U is a playlist file format that contains a list of audio or video files for playback. It does not store actual audio data but references the locations of media files, making it a popular choice for organizing and playing back media collections in sequence.

Why convert m4b to m3u?

Converting an M4B file to an M3U playlist is useful if you want to create a playlist from the chapters or segments of an audiobook, or if you have split an M4B into multiple audio files and wish to play them in order using a media player that supports M3U playlists.

How to convert m4b to m3u

Direct conversion from a single M4B file to an M3U playlist is not straightforward, as M4B is a single audio file and M3U is a playlist referencing multiple files. The typical process involves:

1. Split the M4B file into individual audio files (e.g., MP3 or AAC) for each chapter or segment.
2. Create an M3U playlist that references these individual files in the desired order.

Recommended software for m4b to m3u conversion

• Chapter and Verse (Windows): Allows you to split M4B files into chapters and export them as separate audio files. After splitting, you can use a text editor or a dedicated playlist creator to make an M3U file.
• Audacity (Windows, macOS, Linux): Import the M4B file, split it into segments, and export each as a separate file. Then, use a text editor to create an M3U playlist referencing these files.
• Foobar2000 (Windows): Supports M4B playback and can convert and split files. Use File → Open to load the M4B, split as needed, and then use File → Save Playlist to export an M3U playlist.

Manual creation of an m3u playlist

After splitting your M4B into multiple audio files, you can create an M3U file manually:

1. Open a text editor (e.g., Notepad).
2. List the filenames of your audio files, each on a new line, in the order you want them played.
3. Save the file with a .m3u extension.

Summary

While there is no direct one-step conversion from M4B to M3U, the process involves splitting the M4B into individual audio files and then creating an M3U playlist referencing those files. Foobar2000 is a highly recommended tool for both splitting and playlist creation due to its robust support for audio formats and playlists.
