AMR - Adaptive Multi Rate

A codec offering a wide range of data rates. The philosophy behind AMR is to lower the codec rate as the interference increases, thus enabling more error correction to be applied. The AMR codec is also used to harmonize the codec standards amongst different cellular systems (including VoLTE) and can operate as a narrowband or wideband version.
