compression, standard, algorithm, file format A non-standard extention of MPEG-2 audio layer 3 by FhG for lowest sampling rates (8-12 kHz) targeting bit rates from 16-32 kbps (possibly 8-160 kbps). (2001-12-04)
- Mpeg-2 aac low profile
compression, standard, algorithm, file format A successor of MP3 allowing transparent coding at data rates of 75-80% of that of MP3. It is very different from MP3, only used MDCT, no subband coding. (2001-12-08)

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. (2001-12-04)

- Mpeg-3
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)
