Notes about the AMR file extension:

To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The AMR file type is primarily associated with 'Adaptive Multi-Rate ACELP Codec'. Speech encoding format used in GSM telephony. The AMR ACELP coder will lower the compression rate as cellular interference increases, thus enabling more error correction to be applied. It also is used to harmonize the codec standards amongst different cellular systems. (ACELP = Algebraic Code Excited Linear Prediction)
