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.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
