Table 1 Comparison of ISO/MPEG audio coding standards 2.1 MPEG-1 The MPEG-1 standard consists of three layers of audio coding schemes with increasing complexity and subjective performance. These layers were developed in collaboration mainly with AT&T, CCETT, FhG/University of Erlangen, Philips, IRT, and Thomson Consumer Electronics.

Genesis of the MP3 audio coding standard. Abstract: In 1988 the International Standardization Organization (ISO) established the Motion Picture Expert Group (MPEG) to develop a digital coding standard for video and audio signals in order to enable interactive video and audio signals on digital storage media. The MPEG Audio Group started with members from …

MP3 (common name). 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. …
