M4B is a file extension for an MPEG-4 part 14 audio layer audio book container file format used by iTunes. An M4B file is very similar to an M4A file but specified for audio books. M4B files support metadata for chapters and bookmarking on supporting players and most commonly uses AAC (Advanced Audio Codec).
M4A is a file extension for an audio file encoded with advanced audio coding (AAC) which is a lossy compression. M4A was generally intended as the successor to MP3, which had not been originally designed for audio only but was layer III in an MPEG 1 or 2 video files. M4A stands for MPEG 4 Audio.
A file with the M4R file extension is an iTunes Ringtone file. They can be created and transferred to an iPhone in order to use custom ringtone sounds.
Custom iTunes Ringtone files in the M4R format are actually just .M4A files that have been renamed to .M4R. The file extensions are different only to differentiate their purposes.

A file with the M4B file extension is an MPEG-4 Audio Book file. They're often seen used by iTunes to store audio books.
