  MPEG-1 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
     powerful algorithm in a series of audio encoding standards
     developed under the sponsorship of the Moving Picture Experts Group
      (MPEG) and formalised by the International Organization
     for Standardization (ISO).
  
     MP3 is very different from Layer 2, using an additional MDCT
     layer to increase frequency resolution.  Its scale factor
     groups are more optimised for the human ear, and it uses
     nonlinear sample quantisation and Huffman coding.
  
     MP3 files (filename extension ".mp3") can be downloaded from
     many World-Wide Web sites and can be played using software
     available for most operating systems (also downloadable),
     e.g. Winamp for PC, MacAmp for Macintosh, and mpeg123 for
     Unix.
  
     MP3 files are usually downloaded completely before playing but
     streaming MP3 is also possible.  A program called a "ripper"
     can be used to copy a selection from a music CD onto your
     hard disk and another program called an encoder can convert
     it to an MP3 file.
