AMR Audio Format

AMR Converter

An AMR file also goes by its full name of Adaptive Multi-Rate Codec File and was developed by Ericsson. The AMR file was designed to store spoken audio – such as MMS messages on mobile devices - in a way that didn’t consume a large amount of storage. Typically, AMR files are stored on mobile devices where storage is at a premium hence the need for a compressed file format like the AMR format. Despite being developed by Ericsson with the intention of being used for Ericsson devices, AMR files can be opened by a range of programs including the VLC Player, Windows Media Player, and Apple QuickTime Player.

WMA Audio Format

WMA Converter

The full name for the WMA format is Windows Media Audio. As the name suggests, it’s an audio format specifically for Windows devices. Microsoft introduced WMA files in 1999 following the popularity of the MP3 format, and two years after the launch of the AAC format for digital music. However, WMA is not as widely used as these two formats.

WMA files generally use lossy compression to make the files smaller. This can mean the audio quality isn’t as high as with some other formats, although lossless versions of WMA are possible if you install newer codecs. Because WMA is a proprietary format, it’s not always compatible with non-Microsoft players or operating systems. However, you can play WMA files with Windows Media Player, Nullsoft Winamp, MPlayer and VLC. You can also use some of these programs, or online tools like Zamzar, to convert WMA files into formats like MP3 or AAC.
