AMR (Adaptive Multi-Rate) is an audio data compression scheme optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP and is now widely used in GSM. It uses link adaptation to select from 1 of 8 different bitrates based on link conditions.
AMR is also a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets allow to store short recordings in the AMR format, and some commercial programs convert between this and other formats such as MP3.
In AMR the sampling frequency is 8 kHz/16-bit.

AMR-WB+ is an audio codec that extends a speech coding standard AMR-WB (Adaptive Multi Rate - WideBand). AMRWB+ adds support for stereo signals and higher sampling rates. Another main improvement is the use of transform coding additionally to ACELP. This greatly improves the generic audio coding. Automatic switching between transform coding and ACELP provides both good speech and audio quality with moderate bitrates.
AMRWB+ supports various internal sampling frequencies ranges from 12.8 kHz to 38.4 kHz.
