MPEG-1 Layer 3 (or MP3) is a 1- or 2-channel perceptual audio coder that provides excellent compression of music signals. Compared to Layer 1 and Layer 2 it provides a higher compression efficiency. It can typically compress high quality audio CD data by a factor of 12 while maintaining a high audio quality.

The tools de"ned by MPEG-4 natural audio coding can be combined to di!erent audio coding algorithms. Since no single coding paradigm was found to span the complete range from very low bit-rate coding of speech signals up to high-quality multi-channel audio coding, a set of di!erent algo-rithms has been de"ned to establish optimum cod-

Description. Perceptual audio encoding format designed for efficient distribution of waveform sound over moderate bandwidth connections; may be used at higher data rates for better fidelity. The compression approach adopted as a part of MPEG-2 has been further refined within MPEG-4; see also AAC_MP4.

MPEG audio coders A higher layer makes a better use of the psychoacoustic model and hence higher compression rate can be achieved. The 3 layers require increasing levels of complexity (and hence cost) to achieve a particular perceived quality, the choice of layer and bit rate is often a compromise between the desired perceived quality and the available bit rate.
