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.
What is AMR? AMR Audio File Format Description
https://www.coolutils.com/Formats/AMR
There are two types of AMR format: NarrowBand (AMR-NB) and WideBand (AMR-WB). Often AMR refers to AMR-NB. Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200-3400 Hz. Compared to WAV AMR files are much smaller in size but are of good quality. AMR is well supported by most of modern mobile telephone handsets.
AMR - Adaptive Multi-Rate Codec File

The file with .amr extension is an audio data format relevant to Adaptive Multi-Rate audio codec; consists of a multi-rate narrowband speech codec which encodes narrowband signals at 4.75-12.2 kbit/s bit rate with toll quality speech starting at 7.4 kbit/s; uses link adaptation to select from one of eight different bit rates based.

It is an audio compression format optimized for speech coding. In addition, the AMR file format can also be used to store spoken audio using the same codec. AMR was adopted as the standard speech codec by 3GPP in 1999 and is now widely used in GSM and UMTS. AMR files can be saved in AMR-NB (narrowband) or AMR-WB (wideband) format.
