G.722 is an ITU-T standard wideband speech codec operating at 48 - 64 kbit/s. Technology of the codec is based on split band ADPCM. G.722 sample audio data at a rate of 16kHz, double that of traditional telephony interfaces, which results in superior audio quality and clarity. The codec is used in tele-conferencing systems where mere toll-quality is inappropriate. A major advantage of G.722 is its relatively low MIPS and memory requirement.
