(MPEG-1, Layer 3) Using MPEG audio, one may achieve a typical data reduction of 1:4 by Layer 1 (corresponds with 384 Kbps for a stereo signal), 1:6...1:8 by Layer 2 (corresponds with 256..192 Kbps for a stereo signal), 1:10...1:12 by Layer 3 (corresponds with 128..112 Kbps for a stereo signal). By exploiting stereo effects and by limiting the audio bandwidth, the coding schemes may achieve an acceptable sound quality at even lower bitrates. MPEG Layer-3 is the most powerful member of the MPEG audio coding family. For a given sound quality level, it requires the lowest bitrate - or for a given bitrate, it achieves the highest sound quality. For the use of low bit-rate audio coding schemes in broadcast applications at bitrates of 60 Kbit/s per audio channel, the ITU-R recommends MPEG Layer-3. (ITU-R doc. BS.1115)
