format, MPEG-2 AAC (Advanced Audio Coding) is unconstrained and can therefore provide better coding efficiency. The most recent development is the adoption of MPEG-4 [ISO, 1999] for very-low-bit-rate channels, such as those found in Internet and mobile applications. Table 1 lists the configuration used in MPEG audio coding standards. 3
