Here's two links describing capturing digital sound from the original AdLib:
I wish I had something like that for the MT-32! 😀
Iirc (but I may well not), the AWE64 has built-in OPL3 circuitry, equal to many OPL clone chips around. I'd find it hard to believe they would actually emulate something they could build easily in hardware.
Well, as I wrote before, I'm using the word "emulate" in a broad sense. Having read the thread you linked to carefully, it seems that the "Creative OPL" chip uses "Creative Quadrature Modulation", patented by Creative(5,900,570 and 6,091,269), to produce an output from FM register writes that sounds mostly like the real YMF262 output. I call that "emulation in hardware", because the "Creative OPL" uses different technology to function like the original Yamaha chip. If you want to call this something other than "emulation", go ahead.
This applies BOTH to the non-SB32 AWE32 and AWE64, according to your first link, basically to anything that uses AWEUTIL /S to initialize the FM, I would assume.
Whether it sounds different from the real OPL3, I cannot tell (I've never owned an AWE64).
Maybe Great Hierophant can post some samples from his AWE32, and I will post some from my AWE64 Gold, along with the original YMF262 output from a SBPro2/early SB16. I have to say though that my AWE64 Gold does NOT have the "high frequency interference" mentioned elsewhere.
Either way, current DOSbox OPL emulation is off, and should be fixed some day, imho.
I would have recommended switching over to the Ken Silverman core, but that one is probably OPL2 only (I haven't checked though), has a different problem (which might be easily fixed however knowing what it is, see above), and I don't know the license.
