The Moving Picture Experts Group (MPEG) designed MP3 as part of its MPEG-1, and later MPEG-2, standards.MPEG-1 Audio (MPEG-1 Part 3), which included MPEG-1 Audio Layer I, II, and III, was approved as a committee draft for an ISO/IEC standard in 1991, [14] [15] finalized in 1992, [16] and published in 1993 as ISO/IEC 11172-3:1993. [7]
MPEG-3 was the designation for an abandoned plan to create a group of audio and video coding standards agreed upon by the Moving Picture Experts Group (MPEG) designed to handle HDTV signals at 1080p [1] in the range of 20 to 40 megabits per second. [2]
MPEG-1 Audio Layer III HD (more commonly known by its abbreviation mp3HD) was an audio compression codec developed by Technicolor, formerly known as Thomson. [ 3 ] It featured lossless compression of audio data, and was usually backwards compatible with the MP3 format by storing two data streams in one file.

MPEG logo Some well known older (up to 2005) digital media formats and the MPEG standards they use. The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications. [1]
There is no formal specification for the M3U format; it is a de facto standard.. An M3U file is a plain text file that specifies the locations of one or more media files. The file is saved with the "m3u" filename extension if the text is encoded in the local system's default non-Unicode encoding (e.g., a Windows codepage), or with the "m3u8" extension if the text is UTF-8 encoded.
The audio coding standards MPEG-4 Low Delay , Enhanced Low Delay (AAC-ELD), and Enhanced Low Delay v2 (AAC-ELDv2) as defined in ISO/IEC 14496-3:2009 and ISO/IEC 14496-3:2009/Amd 3 are designed to combine the advantages of perceptual audio coding with the low delay necessary for two-way communication. They are closely derived from the MPEG-2 ...
MPEG-2 Part 3 also defined additional bit rates and sample rates for MPEG-1 Audio Layer I, MPEG-1 Audio Layer II and MPEG-1 Audio Layer III (the first version of MP3). [6] The MPEG-2 Part 3 should not be confused with MPEG-2 Part 7: AAC a.k.a. MPEG-2 NBC (Non-Backward Compatible) - the MPEG-2 Advanced Audio Coding with support for multichannel ...
