Re: IBM PC Speaker RC values?

Though it sounds like you have a much greater error than 1 cycle in 288 at the moment. You make a good point here... We *know* that the innerloop is 288 cycles (give or take 1 cycle every now and then, as we saw on the spectrum analysis). There is exactly one out-instruction to port 0x42 in every …

It's still not as clean as an Amiga. That's the quality you should be aiming for IMO. Preceding the R2R ladder with a latch powered by a low noise supply might help improve things. You can't compare the software mixer in Crystal Dream with an Amiga. It's an early MOD replay routine, only uses 8-bit …

source engine supported DX6-7-8-9 Pretty sure it doesn't. At least, I'm talking about the API. It only uses the DX9 API as far as I know, in any version ever released. It does however have renderpaths for DX7 and DX8-class hardware, so it runs fine on a GF2, GF3, original Radeon or Radeon 8500. …

That's because Half-Life Source is the port of HL to the new Source engine of HL2 at the time. Which was a DX9-only engine. Maybe it is now, but back in the day there was definitely a DX8 renderer available via a command line switch. http://forums.steampowered.com/forums/showthread.php?t=1421458 …

Spoiler alert: A real Speech Thing sounds extremely good . Thanks for the video! And indeed, it sounds excellent. Most clones don't do it justice at all. I think the most apparent is at the start of the demo, when the synth strings come in. They sound a bit noisy on the CVX-2, but very clean on the …

ps. anyone knows a program that allows 2x LPTDACs to be used for stereo sound? FastTracker II has a "SoundPlayer LPT1+LPT2" option, which should work. Not sure if CD and CD2 also support this. THey do have a stereo SoundPlayer option, but you can only choose one port, I think... Might be the for …

I just opened my copy of Half-Life Source on Steam and there's nowhere I can select a renderer. It just assumes you have DirectX now. It's using 9.0c. That's because Half-Life Source is the port of HL to the new Source engine of HL2 at the time. Which was a DX9-only engine. On Windows it still is, …

The buzzing (and slowness) in the 8088MPH mod player is almost certainly due to inaccuracies in the timing of your emulated CPU causing samples to be emitted at irregular intervals instead of exactly every 72 PIT cycles. I second that, the mod player is definitely running considerably slower than …

I'd offer to make you an ISO of my retail Half-Life CD, but I don't know if that'd break any rules on the forum here. You clearly already have bought a copy of the game, so it's not like you're pirating anything. Mine works with my Voodoo2 cards just fine. In fact, all this talk about it...I'm …

Re: SB1.5, SB2.0, SBPro2, SB16 audio comparison.

Posted on 2016-12-30, 19:35

The SB16 is still not a good card for DOS gaming when used solely, but it is a good companion to the SBPro to complete the SBPro where it lacks, mainly as a Wavetable host and MPU-401. I'm actually very fond of this idea. Not so much the pairing of the SBPro2 with an SB16 proper, but rather, with …

Re: SB1.5, SB2.0, SBPro2, SB16 audio comparison.

Posted on 2016-12-30, 11:36

Looking at the graph, the SB16 let's a bit more of the "good highs" through, and then filters out the "bad highs" very thoroughly. Yea, and that's where the 'problem' lies. It sounds different from the earlier SBs. If you're used to how a game sounds on an early SB, then the extra high frequencies …

I've received mine yesterday, and did a quick test on my 286 with Crystal Dream. I was positively surprised by the sound quality. It's much better than the one I built myself many years ago. The DAC sounds very clean, almost no hiss or 'noise' coming through from the PC, and as about little …

Re: SB1.5, SB2.0, SBPro2, SB16 audio comparison.

Posted on 2016-12-29, 19:35

I should add that SB1.5 and SB2.0 are VERY sensitive to CPU speed and many games break the OPL2/Adlib music in a Pentium. That includes popular games like Doom, Prince of Persia 1/2, Mortal Kombat 2, DOTT, etc.. That is probably because of the OPL2, which requires delays between commands. Most …
