Open M4B File

A file with the M4B extension is an audio book file that conforms to the MPEG-4 standard.

M4B files are often used by iTunes to store audio books.

Some media players use the M4B format to store digital bookmarks along with the audio, allowing you to pause playback and then resume it later. This is one of the reasons why they are preferred over MP3s, which cannot save their place in the archive.

In Another way, the M4A audio format is basically identical to M4B, except those file types are used for music rather than audiobooks.

The iPhone, an Apple product, also uses the MPEG-4 audio-type format for ringtones, however those files are saved with the M4R extension.

Open an M4B file

There are various methodologies, depending on the device, for opening an M4B file.

For example on the iPhone, iTunes is used as the main program to play M4B files.

However, iTunes is also useful on a computer, to transfer audiobooks to an iPhone or other iOS device.

On the other hand, Windows Media Player works too, but the extension may not be associated with the software, therefore you may have to open Windows Media Player first and then open the M4B file manually from the main menu.
