compression, standard, algorithm, file format
An extention of MPEG-1 audio layer 3 for lower sampling rates (16-24 kHz) targeting bit rates from 32-64 kbps (possibly 8-160 kbps). It is often combined with MPEG-2 LSF.
- Mpeg-2 mc
MPEG-2 Multi Channel Extention
compression, standard, algorithm, file format A proposed variant of the MPEG video and audio compression algorithm and file format. MPEG-3 was intended as an extension of MPEG-2 to cater for HDTV but was eventually merged into MPEG-2. Not to be confused with MP3 – MPEG-1 layer 3. [Technical details?] (1999-01-06)
compression, standard, algorithm, file format A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

- Mpeg-4 aac main profile
compression, standard, algorithm A successor of MP3 allowing transparent coding at data rates of 70-75% of that of MP3. It is very different from MP3, only used MDCT, no subband coding. It is much more complex that MP3 and MPEG-2 AAC Low Profile. (2001-12-08)
