AMR Player is an AMR audio file player that basically reads all AMR files, or adaptive multi-rate, which is an audio data compression scheme that is useful for speech coding. An AMR file is a type of audio format that is readable and played by different applications including standard audio player or recorder and VoIP program. However, AMR Player is a compatible AMR file reader that plays this kind of audio file on a computer. This is not only a sole AMR audio file reader or player but also a converter. It converts other audio file formats which are WAV and MP3. It is offered to convert MP3 to AMR or vice versa, and WAV to AMR or vice versa. Another feature of AMR Player is that it has simple, easy-to-use and manageable interface. Just click the button “Add Files” from the main interface and select any AMR file or .amr as the file extension to play it. The software alone can decode that file to provide an audio or music playing on the background.
