DPCM

(Differential PCM) A PCM technique that codes the difference between sample points to compress the digital data. Because audio waves propagate in predictable patterns, DPCM predicts the next sample and codes the difference between the prediction and the actual point. The differences are smaller numbers than the numerical value of each sample on the full scale and thereby reduce the resulting bitstream. See PCM, ADPCM and sampling.
