 G.722.2 (AMR-WB) VocoderCompany Description: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. GAO´s algorithm utilizes ACELP technology. Both the IP network and the 3G network use the same codec which provides seamless interoperability.FEATURES: -ITU-T G.722.2 compliant and passes all ITU-T test vectors. -Full and half duplex modes of operation. -Adaptive Multi-Rate ranges from 6.6kbit/s to 23.85 kbit/s. -Multi-Channel ready. -Optimized C or Assembly code.
