Adaptive Multi-Rate Audio Codec (AMR or amr-nb GSM-AMR) is an audio print format optimized for speech encoding. The AMR codec language is a huge multi-rate narrowband codec language that encodes narrowband signals (200-3400 Hz) with variable bitrates from 4.75 to 12.2 kbps, and quality over long distances [3 ] starting at 7.4 kbps.
AMR, Adaptive Multi-Rate Speech Codec
https://www.loc.gov/preservation/digital/formats/fdd/fdd000254.shtml
From the VoiceAge Web site (consulted in April 2007): The proven, highly efficient and very robust AMR (Adaptive Multi-Rate) narrowband codec is the 3GPP mandatory standard codec for narrowband speech and multimedia messaging services over 2.5G/3G wireless systems based on evolved GSM core networks (WCDMA, EDGE, GPRS). . . . AMR operating at various bit …

VoiceAge - AMR (Adaptive Multi-Rate) standard
http://www.voiceage.com/AMR-NB.AMR.html
The AMR (Adaptive Multi-Rate) standard is a speech coding algorithm operating at eight bit rates in the range of 4.75 to 12.2 kbps and was specifically designed to improve link robustness. This technology was initially developed for GSM systems, the single most deployed 2G mobile telecommunication standard worldwide. The AMR narrowband codec was standardized by the …

The AMR codec was adopted by 3GPP in October 1988 and it is used for both GSM and circuit switched UMTS / WCDMA voice calls. The AMR codec provides a variety of options for one of eight different bit rates as described in the table below. The bit rates are based on frames that are 20 millisceonds long and contain 160 samples. The AMR codec uses a variety of different …
