What's MP3?

Before we handle the difference between M4B and MP3, let's quickly define the term. MP3 is a short form for MPEG-1 Audio Layer. It is one of the commonly distributed audio files used nowadays to store a song or the whole CD; it requires minimal hard drive space. MP3 was developed by Moving Pictures Expert Group (MPEG). It's an audio format that uses a compression algorithm that downsizes the entire file size—also called 'lossy compression' because it selectively removes chunks of data that can hardly be heard by the human ear without them noticing.

What is M4B?

The M4B is a file extension commonly used by audiobooks downloaded from the Apple iTunes Store, encoded with the Advanced Audio Codec. M4B is not supported by several media players, especially Apple's FairPlay DRM protected audiobooks files. For Windows, it’s playable on the Microsoft Windows Media Player, iTunes, Microsoft Zune, and other media players. As for Mac, you can use QuickTime Player, 5K Player, iTunes, and other M4B players to play M4B audiobooks.
