Mp2

MP2 began in the late 1980s as part of the ISO's Moving Picture Experts Group (MPEG) effort to standardize digital audio and video encoding for digital radio and TV broadcasting (DAB, DMB, DVB), and use on Video CD.The MPEG-1 audio standard was based on the existing MUSICAM and ASPEC audio formats.[3][4] The MPEG-1 standard, including the three audio "layers" (encoding techniques) now known as MP1, MP2 and MP3, was finalized by December 1991 in the committee draft of ISO-11172.[5][6] MPEG audio was further advanced through its Layer III (MP3) component, which allowed for even lower bitrates.
