The Yamaha YMF262, known more colloquially as the OPL3, is a microchip designed to create audio waveforms. It is an improved version of the YM3812 (OPL2) with the following features:

  • Twice as many channels (18 instead of 9)
  • Simple stereo (hard left, center, or hard right)
  • 4 channel sound output
  • 4 new waveforms (alternating-sine, "camel"-sine, square, and logarithmic sawtooth)
  • 4 oscillator mode, pairing 2 channels together to create up to six 4 oscillator FM voices
  • Reduced latency for host-register access (the OPL2 had much longer I/O access delays)

The following sound cards utilized the YMF262:

Release Company Device
1992-??-?? Creative Sound Blaster Pro 2.0
1992-??-?? Ad Lib AdLib Gold 1000
1992-??-?? Creative Sound Blaster 16
1994-03-?? Creative Sound Blaster AWE32

This list is meant to be in chronological order, but many release dates are missing.

Emulation Status
