Sound Chip

A sound chip is an integrated circuit (i.e. "chip") designed to produce sound. It might do this through digital, analog or mixed-mode electronics. Sound chips normally contain things like oscillators, envelope controllers, samplers, filters and amplifiers. During the late 20th century, sound chips were widely used in arcade game system boards, video game consoles, home computers, and PC sound cards.
