The AMR codec, also known as Adaptive Multi-Rate audio codec, is an audio compression format developed by Ericsson. The audio format is specially optimized for speech coding. AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband signals at variable bit rates ranging from 4.75 to 12.2 Kbit/s with toll quality speech starting at 7.4 Kbit/s, so it can provide a very outstanding speech audio performance.
