Microsoft initially developed the Windows Media Audio (WMA) file format to compete with the MP3 file format. WMA is both an audio codec and an audio format. WMA has evolved since its inception in 1999, with several updated versions: WMA Pro, WMA Lossless, and WMA Voice. It is a key component of Windows Media, which Microsoft discontinued.

 

How to open a WMA file?

As a key component of Windows Media, Windows Media Player supports WMA files and is usually the default program for opening these. Because of their relative ubiquity, however, many other players and programs support the file type. WMA files are also frequently used in online streaming.

 

Other programs that can open WMA files include VLC media player and UltraMixer. For mobile devices, try OverDrive Media Console, which has separate versions for Apple iOS, Google Android, and Windows Phone/Windows 10 Mobile.

MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats.

 

How to open an M4A file?

M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. For Apple users, iTunes is the default program to open M4A files. For Windows users, the default program is Windows Media Player. Users can also preview M4A files by highlighting the file and pressing the spacebar.

 

Additionally, M4A opens in VLC media player, Adobe Premiere Pro, Elmedia Player, Winamp, and a host of other programs.
