MPEG-1 and MPEG-2 Layer II Audio Encoding
https://www.loc.gov/preservation/digital/formats/fdd/fdd000338.shtml
Full name. MPEG-1 and MPEG-2 Layer II Audio Encoding. Description. Lossy audio compression that derives from the MUSICAM audio codec. This format may be referred to as MP2 and employs perceptual compression. This means MP2's compression takes out information that is imperceptible in the human auditory range. MP2 is the dominant audio …

Future Work MPEG-1 audio lays the foundation for all modern audio compression techniques Lots of progress since then (1994!) MPEG-2 (1996) extends MPEG audio compression to support 5.1 channel audio MPEG-4 (1998) attempts to code based on perceived audio objects in the stream Finally, MPEG-7 (2001) operates at an even higher level of ...

Audio encoding is a technique used for encoding scheme digital audio files. This technology can be used for coding audio files at medium to high bit rates. Advanced audio coding is designed to be the logical successor to MP3 (ISO/MPEG Audio Layer -3) and can offer better sound quality than its predecessor at the same bit rate.

MPEG is a family of encoding standards for digital multimedia information •MPEG-1: a standard for storage and retrieval of moving pictures and audio on storage media (e.g., CD-ROM). • Layer I • Layer II • Layer III (aka MP3) •MPEG-2:standard for digital television, including high-definition television (HDTV),
AUDIO CODING: BASICS AND STATE OF THE AR T

adoption of ISO/IEC IS 11172 in late 1992. The audio coding part of MPEG-1 (ISO/IEC IS 11172-3, see [1] describes a generic coding system, designed to fit the demands of many applications. MPEG-1 audio consists of three operating modes called layers with increasing complexity and performance from Layer-1 to Layer-3.

Yes. MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS -quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable / satellite TV and digital audio broadcasting (DAB) practical.
MP3 (MPEG Layer III Audio Encoding) - Library of Congress
https://www.loc.gov/preservation/digital/formats/fdd/fdd000012.shtml
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). 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.
