ADPCM
Adaptive Pulse Code Modulation of audio waveform sampling that records the difference between samples is recorded rather than the actual values. This increases fidelity with lower resolution than conventional PCM. (See also Audio and PCM )

ATM Forum
ADPCM
Adaptive Differential Pulse Code Modulation: A reduced bit rate variant of PCM audio encoding (see also PCM). This algorithm encodes the difference between an actual audio sample amplitude and a predicted amplitude and adapts the resolution based on recent differential values.
