- Description
- 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.
- AMV (Actions Media Video) is a proprietary video file format, produced for MP4 players, as well as S1 MP3 players with video playback. There are two different versions of this format: an older one for Actions chips, and a newer one for ALi’s M5661 chip, sometimes called ALIAVI.
