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]
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.

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.

Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO/IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio). Improvements include: more sample rates (from 8 to 96 kHz) than MP3 (16 to 48 kHz);

M3U (MP3 URL [1] [2] or Moving Picture Experts Group Audio Layer 3 Uniform Resource Locator [3] in full) is a computer file format for a multimedia playlist.One common use of the M3U file format is creating a single-entry playlist file pointing to a stream on the Internet.
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) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.
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.
