Over the years, a number of computers, video game consoles, and peripheral devices used the AY-3-891x series of chips.

It improved on nearly every aspect of the original design and could also run in AY-3-8910 compatibility mode which made it mostly backward-compatible with the AY-3-8910. The AY8930/P was designed and sold by General Instrument's offshoot company, Microchip Technology. Changing all three volumes even allows 8-bit on mono. This allows to play unsigned 4-bit PCM samples.

Due to those limits, many people generated envelopes themselves in software and set all three volumes manually.Ĭhanging a volume produces a click the greater the change, the louder.

However, you can only choose one speed for both, and all channels get the same envelope. You can enable attack (volume up from 0 to 15) and/or decay (volume down from 15 to 0), at the end optionally reversed and/or looped.

Volume, either from 0 to 15, or fed by the single envelope generator.

Further divided by 4095, it equals the minimum frequency. The highest possible frequency is the sound chip's clock frequency divided by 16. On each of channels A, B and C, you can choose: Some arrangers have mixed short noise drums over a square wave bass. Consequently, all noises share the same pitch, and each noise shares the volume of the square wave it accompanies or replaces. Unlike the SN76489, the noise does not have its own channel, but is optionally mixed into any combination of square wave channels. The chip was also very popular in slot machines of the 1980s. However, it still held a niche in games that didn't require high-fidelity sound for several more years, particularly among mahjong, trivia, adult, and gambling games. The AY-3-8910 series began dipping in popularity in 1985, and by 1987 it had been eclipsed by Yamaha's new family of audio chips. One single chip can be stereo, since all channels are output through their own pin. The frequency ranges differ on each platform. Though they were not designed for PCM, they could be programmed to play audio well enough to understand speech.

The chip features 3 tone generators, a noise generator, and an envelope generator which provides amplitude control. These LSI circuits were able to produce various sounds by accessing them with software. The series consists of several chips including the 8910, 8912, 8913, 8914, 8916, and 8917, each with a revision, as well as several licensed clones. The series was very successful, becoming the most-used audio chip of the arcade industry through the early 1980s. The AY-3-8910 is a series of programmable sound generators (PSGs) designed by General Instrument at the end of the 1970s.
