I think ADPCM might be:
  Adaptive Delta Pulse Code Modulation

Delta means it encodes the difference between successive samples, which
usually takes fewer bits than the samples themselves.  Adaptive might
have something to do with changing resolution to match the input stream,
using the fewest bits possible ... but I'm not sure about that.
