Adaptive Digital Pulse Code Modulation



(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.

[Used where? Does the Sony minidisk use ADPCM or ATRAC?]
