- 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.
- Video file encoded with the MPEG-2 codec, which is mainly used for over-the-air, satellite, and cable digital TV signals and DVD video; uses lossy compression for audio and video to significantly reduce the size of the video data; not as efficient as the H.264 format.
