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.
A 3GP file is a multimedia file saved in an audio and video container format developed by the 3rd Generation Partnership Project (3GPP). It stores video and audio streams that are transmitted between 3G mobile phones and over the Internet.
