MPEG Layer III audio encoding is defined in two ISO/IEC specification families (MPEG-1: 11172-3 and MPEG-2: 13818-3). Description MP3 compression employs perceptual coding , an approach based on psychoacoustic models that permit the codec to discard or reduce the precision of audio components that are less audible to human hearing.

MPEG Audio Layer 3 Layer 3 is one of three coding schemes (layer 1, layer 2 and layer 3) for the compression of audio signals. Layer 3 uses perceptual audio coding and psychoacoustic compression to remove all superfluous information (more specifically, the redundant and irrelevant parts of a sound signal.

MPEG-1 Audio Layer 3 (MP3) is a digital audio format and technology that is used for compressing a sound sequence to a smaller file, but still preserving the original audio quality. It is considered a lossy format for audio.

MPEG Layer-3 EBU TECHNICAL REVIEW– June 2000 6 / 15 Popp and Brandenburg Sampling frequency MPEG audio compression works on a number of different sampling frequencies. MPEG-1 defines audio compression at 32 kHz, 44.1 kHz and 48 kHz. MPEG-2 extends this to half the rates, i.e. 16 kHz, 22.05 and 24 kHz. “MPEG-2.5” is the name of a pro-

MP3 codecs have quite a complicated licensing agreement. AUDIOWRITE supports writing MPEG-4 audio using AAC encoding. This is better than MP3 in that it provides better quality at lower bitrates. This is supported on Windows and Mac. If you are looking to write compressed audio, you can give this a shot.

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.
