Well there's sound, so it does something.
At some places it sounds like the delay between the commands is wrong,
but hard to tell without any code, without any comparison how it should
sound and everything.

I thought everyone know the Doom's music =)

ok I attached the original song (what DosBOX produces, and not from an original chip).

Not if it's seriously messed up.

as I see you dont see the problem - can I give any further information?

How shall i derive what is wrong in your code listening to one example?
The only thing i noticed i've already written above:

Okay, then here is all code: http://pastebin.com/f47aff5e3 written in MVS 2005.

And some new records: DOTT - which sounded a bit accuracly, 90% DNUKEM2 - whics is a bit worser, 60% and dont forget DOOM wich was catastropha 😮

So, it do works with some songs but DOSBOX does it almost 100% with all games. I hope I could help 😀

Well could be that the timers are simply not precise, check the delphi docs.

Is WriteStream called at millisecond resolution with appropriate parameters?

sadly not, its laggy in C++ too, but its not matter yet.

No and its not predictable when its called. Its called when the stream can accept "lenght" amount of data. "Lenght" is never the same, each calling its got another value.

ummm nevermind it can be set to millisecond resolution SO the speed/timing is perfect now, STILL the quality is bad 😖

For reference here's a rather noisy recording of Doom E1M1, ymf262. The waveforms in this should be your target 😀

A bigger challenge is Heretic E1M5, which no emulator gets right ever!

I have all of the Doom, Doom II, Heretic, and Hexen MIDIs extracted right out of the original WADs if you want a recording of any of them. I can also fire them up on one of my old systems if you want the original sound.

Playing them externally wouldn't use Doom's GENMIDI lump for defined opl instruments.

Then this is the sollution? ymf262 instead YM3812?

If you're recording opl3, it might.

but for a while lets just stick with opl2.

hm as I overviewed DOSBOX source again, I see the mixer do something after creating the FM sound. What is that? Its the Addsamples method

Moves the data stream into an audio buffer depending on its type.

If you stick to opl2 be sure your recording is opl2, too (see dosbox.conf)

we dont understand each other 😢

I see dosbox uses M3812UpdateOne, YM3812Init... in cases of OPL2. Thats why I only use them too. Still, it sounds different for me

EDIT: and since the ADPLUG+WINAMP plays it perfectly back, and DRO cant even record opl3 music, Im sure the mistake is not with it

deeped, I think you would be interested in my opl2wav, dro/raw/imf/got player written in Delphi.
Source included, feel free to adapt it to your needs (and tell me if you make anything cool with it).

hmm very fucking good job - especially that the .obj files can be used. I didnt know that 😮
