G.722.2 (AMR-WB) Vocoder
G.722.2 (AMR-WB) Vocoder
ITU-T G.722.2 is an international standard for wide-band audio compression. The G.722.2 standard uses an Adaptive Multi-Rate Wide-Band (AMR-WB) codec. GAO’s G.722.2 multi-rate codec operates between 6.6 kbit/s to 23.85 kbit/s. By utilizing a wide-band of 50Hz to 7kHz, GAO’s G.722.2 algorithm provides higher-than-toll quality speech. The algorithm utilizes ACELP technology. Both the IP network and the 3G network use the same codec which provides seamless interoperability.
