Both pre- and postmasking are being exploited in MPEG/Audio coding algorithms. Perceptual Coding Digital coding at high bit rates is dominantly waveform-preserving, i.e., the amplitude-vs.- time waveform of the decoded signal approximates that of the input signal.

MPEG-2 audio coding without backwards compatibility, called IMPEG-2 Advanced Audio Coding (AAC), offers the highest compression rates. Typical application areas for MPEG-based digital audio are in the fields of audio production, program distribution and exchange, digital sound broadcasting, digital storage, and various multimedia applications.

to this reason the mpeg coding algorithms are usually refered to as hybrid block-based dpcm/dct algorithms. 9.3 mpeg-1 - a generic standard for coding of moving pictures and associated audio for digital storage media at up to about 1.5 mbits/s the video compression technique developed by mpeg-1 covers many applications from interactive systems on …

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
