Abstract
Based on frequency-domain techniques, coding of high-quality audio with bit rates down to 64 kbit/s is possible. This performance is achieved using perceptual coding. Transform coding can be used to get the best performance at very low bit rates. Real-time implementations of several types of low bit rate codecs have been developed. Standardization of low bit rate audio coding systems is under way in ISO/IEC JTC1/SC2/WG11 (MPEG/Audio).Keywords
