What is M4A?
Full name
MPEG-4 Audio Layer
Format type
Audio
Developed by
The International Organization for Standardization
Description
M4A is described in the MPEG-4 Part 14 standard created by the International Organization for Standardization. While MP4 files can contain audio and video, M4A is designed for audio only. This file type can be used to store music, podcasts, or audiobooks. Apple devices and programs support M4A natively, and it is the most common format in iTunes. On Windows, you might need to install an additional codec pack to open and play an M4A file.
File extension
.m4a
Technical details
In the M4A format specification, you might see one of two codecs: AAC or ALAC. ALAC provides lossless compression, so these files might be relatively large compared to those compressed with AAC, which offers lossy compression. If you’re wondering how to choose between these codecs when converting files to M4A, think about the audio playback. Lossless compression means better quality.
Associated programs
Windows Media Player 12 (older versions will require additional codecs), iTunes, QuickTime, and VLC
What is M4B?
Full name
MPEG-4 Audiobook File
Format type
Audio
Developed by
Apple
Description
Apple created the M4B format for playback of audiobooks, radio programs, and podcasts. The main feature that distinguishes the M4B file type is that the files support the use of bookmarks, so the listener can return to a previously defined point. If you’re wondering how to open M4B audio tracks, refer to the associated programs below.
File extension
.m4b
Technical details
Files with the M4B specifications are exclusively encoded with either lossy AAC or the Apple Lossless codecs. The contents of an M4B file can be protected with DRM (Digital Rights Management). In this case, users will need a corresponding (possibly fee-based) license to play these M4B audio tracks.
Associated programs
iTunes, QuickTime Player, Windows Media Player, and VLC
