G.722.2 Adaptive Multi-Rate (AMR) Wideband (WB) is the first wideband codec to be standardized for both wireless (3GPP) and wireline (ITU-T Recommendation G.722.2) applications.
G.722.2 / AMR-WB provides improved speech quality due to a wider speech bandwidth of 50–7000 Hz..
The G.722.2 audio coder encodes 16 kHz sampled audio signals for transmission, and compresses the signals to a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s.
Coding Rate: 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 kbps
Sampling Rate: 16 kHz
Delay: 20 msec
Supported by ARM processor-based devices
