code modulation (DPCM) data compression scheme is proposed. Although standard DPCM structures are widely used in single-talker speech coding systems, the models and statistical assumptions well-known for speech signals are not applicable to arbitrary audio signals such as music. The new DPCM formulation presented here includes a recursively indexed

Histogram of DPCM sampled image. DPCM - practical uses. In practice, DPCM is usually used with lossy compression techniques, like coarser quantization of differences can be used, which leads to shorter code words. This is used in JPEG and in adaptive DPCM (ADPCM), a common audio compression method. ADPCM can be watched as a superset of DPCM.
