  Adaptive Digital Pulse Code Modulation
  ADPCM
  
     <communications> (ADPCM) A compression technique which
     records only the difference between samples and adjusts the
     coding scale dynamically to accomodate large and small
     differences.  ADPCM is simple to implement, but introduces
     much noise.
