1. MPEG-1 audio layer 3
   (music, file format) (MP3) A digital audio compression algorithm that acheives a compression factor of about twelve while preserving sound quality. It does this by optimising the compression according to the range of sound that people can actually hear. MP3 is currently (July 1999) the most powerf...

3. MPEG-2 audio layer 3
   (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)

4. MPEG-2.5 audio layer 3
   (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)

5. 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)

6. MPEG-3
   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. MPEG-3 should not be confused with MP3 which is MPEG-1 layer 3 popularly used for audio encoding.

7. MPEG3
   is intended for HDTV and video-on-demand, as then huge amounts of data have to be transmitted. It is today especially used for audio compression: a very high rate of compression can be reached without great loss of quality.
