Programmable sound generator
SOUND CHIP THAT GENERATES AUDIO SIGNALS BUILT FROM ONE OR MORE BASIC WAVEFORMS
Programmable Sound Generator
A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation.
