All About Storage

AMR file is an Adaptive Multi-Rate compressed audio. Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech coding. Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and is now widely used in GSM. It uses link adaptation to select from one of eight different bit rates based on link conditions. 

AMR is also a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets will allow you to store short recordings in the AMR format, and some commercial programs exist to convert between this and other formats such as MP3, although it should be remembered that AMR is a speech format and is unlikely to give ideal results for other audio. The common filename extension is .amr.

The easiest way to open an file extension AMR is to double-click on it and let your PC decide which default application should open the file. If no program opens the file extension AMR file then you probably don't have an application installed that can view and/or edit AMR files.

File extension AMR is executable by Apple's Quicktime Player and RealNetworks' RealPlayer can both open these files for listening. Users who wish to edit must convert to another format supported by their editing software. Mobile Media Converter is a free conversion program for Windows and Linux, that handles both audio and video conversion using ffmpeg. The program supports many of the common formats like .mp3, .ogg, .wma, .wav, .mpeg, and .3g2. Allok MP3 to AMR Converter, Mobile Ringtone Converter, Mobile AMR converter, FLAC MP3 Converter, and EZ Ringtone are other programs available conversion of .amr files.
