Philips SAA1099 - an electronic component, a chip of a 6-voice sound generator. It was used in the 1980s in a number of devices, including:

• British home computer SAM Coupé
• Creative Labs Sound Card Creative System System ( C / MS ), also sold at RadioShack stores under the name Game Blaster . It contains 2 such microcircuits, which gives 12 independent votes.
• Sound Card Creative Sound Blaster 1.0. In addition to this chip, it also contains a frequency modulation sound generator chip - OPL2 (also known as YM3812 ), which later became much more popular.

SAA1099 generates a square waveform and noise (with three different frequencies). Its sound synthesis capabilities are similar (software incompatible!) To General Instruments AY-3-8910 . The main feature of the chip is a stereo output, with the ability to independently adjust the volume of the audio outputs of the left and right channels.
