How to Play a M4A File
M4A files provide better audio quality at a greater compression rate than MP3 files. Apple distributes popular song titles on M4A files at its iTunes Store. You can play these files on a VLC media player, an open-source software program that can handle many types of files.
Download VLC media player. Go to the VLC website (see Resources) and, based on your computer's operating system, download the appropriate setup file.
Install VLC media player. Open the VLC setup file after you have downloaded it from the website. The contents will self extract onto your computer.
Prepare to play your M4A files. Drag and drop them into the VLC player. The M4A file name will appear on the VLC's play list screen.
Press the play button. Your VLC media player will start playing your M4A file.
