Technical details for AMR file

AMR files are able to encode 200-3400 Hertz signals from 4.74 - 12.2 Kilobits/ sec with good quality that begin at 7.4 kbit/s. This approach was adopted by 3GPP in 1999. It used link adaptation to select from 8 different bitrates. AMR files optimize link adaptation to elect the best codec available in order for it to be used with radio channels and capacity requirements. Good connection is required to prevent audio quality loss.
