- 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.
- An RM file is a multimedia file used by RealPlayer, an audio and video playback and streaming program. It contains audio or video data or a link to a streaming media file, which is played back as it is downloaded. RM files are commonly used for streaming content over the Internet such as video and Internet radio.
