Details from https://en.wikipedia.org/wiki/MOS_Technology_6581:
The MOS Technology 6581/8580 SID (Sound Interface Device) is the built-in programmable sound generator chip of Commodore's CBM-II, Commodore 64,[1] Commodore 128 and Commodore MAX Machine home computers. It was one of the first sound chips of its kind to be included in a home computer prior to the digital sound revolution.
Together with the VIC-II graphics chip, the SID was instrumental in making the C64 the best-selling home computer in history,[2] and is partly credited for initiating the demoscene.
Features
three separately programmable independent audio oscillators (8 octave range, approximately 16 - 4000 Hz)
four different waveforms per audio oscillator (sawtooth, triangle, pulse, noise)[6]
one multi mode filter featuring low-pass, high-pass and band-pass outputs with 6 dB/oct (bandpass) or 12 dB/octave (lowpass/highpass) rolloff. The different filter modes are sometimes combined to produce additional timbres, for instance a notch-reject filter.
three attack/decay/sustain/release (ADSR) volume controls, one for each audio oscillator.
three ring modulators.[6]
oscillator sync for each audio oscillator.
two 8-bit analog-to-digital converters (typically used for game control paddles, but later also used for a mouse)
external audio input (for sound mixing with external signal sources)
random number/modulation generator
