The Yamaha YMF262, known more colloquially as the OPL3, is a microchip designed to create audio waveforms using FM synthesis. 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 operator mode, pairing 2 channels together to create up to six 4-operator FM voices
  • Reduced latency for host-register access (the OPL2 had much longer I/O access delays)

The following sound cards utilized the YMF262:
