My favorite tunes to compare OPL2 emus and cards are a couple of DMX ones:

Heretic E1M5
Doom E2M2

these two usually expose percussion, distortion, and channel limits, and they're much much much worse on every imitation hardware i've heard.

I agree with you, the sound of nuked OPL3 emulation core is more accurate than others.

Here is prince of persia FLAC recorded from Sound Blaster 16 CT1740 (YMF262-M):
hwm.us.to/famimusic/Upload/Prince%20of% ... F262).flac
vs the nuked emu:
http://hwm.us.to/famimusic/Upload/pop_nuked_emu.flac 😀

There is some horribe and rather loud distortion between 0:35 and 0:38 in the nuked recording which is not present in the YMF262 file. I have the same distortion in that moment no matter what emulation I use. I suspect it has something to do with resampling, but I'm not sure. Also I might be imagining things, but to me YMF262's highs sound softer, while nuked sounds too sharp on highs. For example, compare 1:20 - 1:30. And again there is some distortion at 1:24 - 1:28, which is not present in YMF262 recording.

I know this is an old topic, but recently I found another OPL3 emulator. This one is the OPAL OPL3 emulator from Reality Adlib Tracker. I made it easier to integrate into projects and wrote a wrapper for it.

I am attaching recordings of arrock1.mid and lion10.mid with this emulator.

Seems lion10.mid exhibits same envelope generator issue as MAME and DOSBox compat cores

I just tested a c++ port of Java OPL3.

What is the reason Nuked OPL is not part of dosbox yet?
Many emulators and professional software adopted it.

For people who compiled Nuked-OPL with DOSBox SVN or using the provided SVN-3990+Nuked by nukeykt in the Patch subforum.
Make absolutely sure that both the Mixer and oplrate set to 49716 in DOSBox config else there is high level of harmonic distortion in the OPL emulation.

Hi James-F,

Regarding this setting of 49716, I am in doubt if it works in my system.

The reason is, if I open Control Panel > Sound > Playback > Properties > Supported Formats, in the Sample Rates table I only see 32.0, 44.1, and 48.0 kHz.

Should I use 49716 in DOSBox-SVN anyway?

Cheers
