- An AMR file is an audio file saved in a compressed audio format developed by Ericsson. It is used by many 3G cell phones for voice recordings such as MMS messages. AMR files incorporate the Algebraic Code Excited Linear Prediction (ACELP) algorithm, which is designed to efficiently compress human speech audio.
- Audio format that uses MPEG-1 Layer II compression to reduce the file size; mainly replaced by the ubiquitous .MP3 format, but is still used for digital radio and digital television broadcasts.
