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.

What is MKV?
Full name
Matroska Multimedia Container
Format type
Video
Developed by
Lasse Kärkkäinen
Description
MKV (or Matroska Multimedia Container) is a free, open source video container format created in 2002. It’s officially called Matroska after the Russian matryoshka dolls because all the video, audio, and subtitle tracks are held within a single file. This format enables synchronous playback of audio and video tracks. Since MKV supports a large number of codecs and even uncompressed video, this format retains the original quality, allowing you to enjoy your videos in HD. Check this table if you want to know how to open MKV files and which programs can play them.
File extension
.mkv, .mk3d, .mka, .mks
Technical details
Videos with the MKV file type have a data channel for each type of track, making this format closer to other media containers such as AVI or MP4. A disadvantage of the MKV format is that very few modern programs can play files with these specifications correctly, so users have to install additional applications or codecs, for example, the VLC player or K-Lite Codec Pack.
