Have you encountered a problem with a M2A file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a M2A file here. In the further part of this page we have added a list of programs that should open your M2A file. It is enough you choose a proper application for your operating system, download and install it.


The file extension M2A identifies audio files in the so-called MPEG-2 audio format. These files are mostly used in video editing and are created by demuxing (demultiplexing) container formats together with a m2v file.

The MPEG-2 audio compression method is multi-channel capable, which is why it can also be found on some DVDs.

In principle, most players should be able to handle M2A files. However, if the extension M2A is not recognized or it does not appear in the file chooser, changing the extension to mpa or mp2 can help.

M2A files are also referred to as Apple MPEG 1/2 audio files. In addition, M2A files are often referred to as MPEG-1 Layer 2 audio files, but their extension is mp2.

How to open a M2A file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the M2A file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a M2A file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support M2A files. At this point we are looking for disk space where the application was installed in and we can link it with a M2A file. Since then, our operating system will use the selected program to support all M2A files.

Other issues

Despite the described problem with M2A there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the M2A file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the M2A file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
