An M4A file is a type of audio file that can be lossy or lossless
(depending on what codec it was encoded with). "M4A" stands for "MPEG-4
Audio", which is basically an MP4 file without video data.
You can open an MP4 file using almost any media player, from VLC to iTunes to the Media Player app on Windows---and more.
An M4A file is an audio file—not to be mistaken with an audiophile—which is an appreciator of music and acoustics of all kinds. Like many other types of audio files, ones with the M4A extension can be opened with multiple programs that you can easily download or may already be on your computer.

What Is an M4A File?
Files with the extension M4A are compressed audio files that are contained in the MPEG-4 format. They are encoded with either the AAC (lossy) or ALAC (lossless) codecs.
M4A is similar to MP4, another type of MPEG-4 file that can store both audio and video information. However, the M4A file type can only ever store audio information. An M4A is always an audio file, while an MP4 is a video file (of course, it can have audio, too.)
If an M4A file has been encoded with AAC, that means it lost some of its data (lossy compression). This is usually done to keep files smaller and more manageable. Alternatively, M4A files can also be encoded with ALAC, which means that almost no data was lost (lossless compression). Though the latter results in higher-quality audio, the files are larger. With that said, audio files don’t usually get that big compared to video files and other types of data.
What Does M4A Mean?
As we mentioned before, M4A is contained in the MPEG-4 format. Specifically, M4A stands for “MPEG-4 Audio”. The “MPEG” part is an acronym for the Moving Picture Experts Group. The “4” part means that it is the fourth iteration of the MPEG file type, which is the most recent as well as the type that retains the highest audio and visual quality.
This group was responsible for the standardization of many commonly used file types. In turn, this made it easier for people to exchange audio and video files in a way that maintained high data quality. These days, they’re still hard at work developing media coding formats, systems, and tools to support said formats, as well as much more.
How to Open an M4A File
You can open an M4A file in basically any media player, from VLC to iTunes to the Media Player app on Windows. Whatever device you’re using, it almost certainly has a preinstalled app that will open an M4A file.
