MPEG-4 Audio Layer (M4B) is the file format that stores audiobooks and podcasts, primarily those that are available on iTunes. The cool thing about this file format is that, unlike MPEG-Audio Layer III (MP3), M4B can store digital bookmarks. This feature allows readers to pause and resume later, just like a physical bookmark in a printed book!

 

How to open an M4B file?

The default program for opening M4B files is iTunes. For cross-platform access, VLC media player is a very dependable option that works on Mac OS X and mobile.

 

On Windows, several options are available. They include Windows Media Player, MediaMonkey, Winamp, and Helium Music Manager.

Apple Lossless Audio Codec (ALAC) is Apple’s lossless audio format, stored inside an M4A container. It compresses a recording to roughly half its original size while preserving every sample, so decoding returns audio identical to the source CD or WAV. ALAC is the natural choice for lossless libraries in the Apple ecosystem, and Apple released it as open-source in 2011, which broadened support well beyond its own devices.

 

How to open an ALAC file?

On Apple devices, ALAC plays directly in the Music app, iTunes, or QuickTime with no setup at all.

 

Elsewhere, VLC media player, foobar2000, and Android all read ALAC. Since ALAC files carry the .m4a extension, they look identical to lossy AAC files in a file listing — check the track properties to tell them apart. To free up space or play the music on limited hardware, convert it with our M4A to MP3 tool.
