Sound chip

From Wikipedia, the free encyclopedia

A sound chip is an integrated circuit (i.e. "chip") designed to produce sound (see chiptune). It might be doing this through digital, analog or mixed-mode electronics. Sound chips normally contain things like oscillators, envelope controllers, samplers, filters and amplifiers.
