G.722.1 Vocoder

ITU-T G.722.1 is an international standard for wide-band audio compression. GAO’s G.722.1 wide-band compression algorithm provides higher-than-toll quality speech. The vocoder operates between a wide-band, 50Hz to 7kHz signal range, at the G.722.1 standard bit rate of 24kbps and 32kbps. GAO’s G.722.1 algorithm is in the form of fixed-point arithmetic and is based on the Modulated Lapped Transform (MLT).
