Voice of the Computer


Audio ICs

The Yamaha OPL Æ chips are the industry standard music synthesizers found in most personal computer audio boards. The OPL3 uses FM synthesis techniques proprietary to Yamaha. The OPL3L is a low power FM synthesizer in a small package. The recently announced OPL3-SA single chip audio solution integrates audio CODEC, DOS games compatibility and D/A converter with FM synthesis in one low-profile package. The OPL3-SA replaces up to four devices used in current SoundblasterÆ compatible audio subsystems, and is ideal for motherboard applications.

For the high end of sound quality, the OPL4 family combines synthesis techniques to produce rich musical sound using Yamaha's unique FM-enhanced wavetable synthesis. The new OPL4-ML combines the FM/wavetable synthesizer with a wavetable sample ROM and General MIDI interface into a low-cost, 100-pin package. The OPL4-ML allows for the first truly cost-effective implementation of wavetable synthesis in the mainstream personal computer.

Yamaha also offers a variety of other audio chips, ranging from special effects to Karaoke to DolbyÆ Pro Logic.
