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 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.
