  lossless audio compression
  
     <audio, compression> Any kind of audio compression in which
     the original signal and the decoded signal are bitwise
     identical.  Lossless audio compression algorithms are usually
     based on a data compression algorithm like PKzip or gzip
     but specialized for PCM audio data.  The signal is divided
     into predictable tonal components and unpredictable noisy
     components.  Tonal components are stored as coefficients of a
     predictor, the remaining signal is coded by a Rice,
     Huffman, or arithmetic coder.
