Adaptive Multi-Rate audio codec or AMR is an audio format that is used in recording audio or speech on mobile devices. When you use the audio recorder of your mobile phone, the file recorded is usually saved by default to AMR. It is smaller than the size of audio file saved in MP3 format. However, this format can only be played on mobile devices. It is not supported by common media players on computers and other devices like Windows Media Player. If you wish to play these files on these devices, you need to convert AMR audio to MP3.

MP3 is the standard audio format supported by most media players. There are free and paid applications that you can use for converting AMR files to MP3 or even other audio formats. There are programs that require installation and there are those that can be accessed online. They have their own benefits so you may want to weigh your options before deciding which application best suits your needs and preference.
