1.) FM Synthesis
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 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:
