Computer system for processing image and sound data using ADPCM stereo coding

摘要

A computer system having a PSG, a volume control circuit, a sound data output unit containing two channels of an ADPCM decoder each using a 32 kHz sampling frequency, a 32 bits CPU, an output control unit, and memories connected to the sound data output unit, the CPU, and the output control unit, respectively. So that the computer system has a high quality sound output function and can reproduce a sound data at high quality.
