POKEY is the most famous of Atari's sound chips. It is resident in every 8-bit computer and 5200 console, and onboard some 7800 cartridges.

 

It's also in many Atari arcade games from the early-mid 1980's.

 

TIA generates the sound (and video) inside the 2600, and is also in the 7800. The sound from TIA is much like a primative version of POKEY.

 

POKEY doesn't natively generate waveforms, only square waves, but has "distortion" and "noise" features. Waveforms can be done by software by directly forcing an amplitude level for a voice.

 

The Atari 400/800 Hardware Manual contains detailed descriptions of POKEYs functions.
