Yamaha OPL3 chip VS. EMULATION

 

This simple test will compare a game soundtrack recorded straight from a soundcard with a YMF262 and a PC emulator.

The OPL aka Operator Type-L are a series of sound chips for low budget synthesizers and mainly PC gaming soundcards based on FM synthesis (read the Yamaha DX7)

YMF262

Comments: Initial OPL bass is more fat and present, DOSBOX is more defined and not aliased- OPL3 kick drum is dirtier but punchier - At 0:19 a deep synth sound is missing in emulation mode.

Is OPL3 100% compatible with OPL2? NOP!

A strange feature called "CSM Composite Sine wave Mode" has not been implemented on OPL3 . This strange and obscure function seems to generates speech synthesis.

comment
geek stuff


"OPL3 is less defined on high frequencies, but it is far more punchier, grit and dirty - a genuine OPL3/2 is recommanded for true audio maniacs or music purposes. Emulation suits 99% of retrogame users."
