I used the WinFilter tool with DOSBox 49716 sampling rate and generated a SBPro2 frequency response and exported it as DOSBoxIIR.c. I lack the programming skills but if anyone can make a test build that passes the PCM audio (only) using this .c file I can measure it and compare to real SBPro2. note: …

It saddens me that DOSBox in 2020 still doesn't have a proper lowpass filtering emulation to sound like original DOS era sound cards. DOSBox sounds shrill with a lot of high frequencies in comparison to a good old DOS era SB card. The SBPro2 (best DOS sound card imo) for example Is a very simple 2nd …

I don't think the massive amount of complaint is from an inability to accept changes, change is welcome when it is good and functioning properly. The amount of complaint is because the result actually is eye straining, and does not look or function like the majority of other forum boards. This new …

So everyone likes the "oldschool " style,,, this ugly deep purple going to stay? Also, something is very wrong with the font, each letter changes line thickness. Moreover, old vogons background colors are "153,153,204" and "165,165,216", soyou got the lighter background color wrong in the oldschool …

Hi Keropi. Here are a few bullet points I test with clone SBPro2 cards: Balance between PCM and FM (OPL3). Lowpass Filtering. Stereo flip, Correct L/R panning, Mono switch. Mixer steps behavior. In my testing a 'good' clone will pass all these tests,, everything else is a bonus. Same thing applies …

Hi Tiido. Does your card fix the mixer problem described here?: Yamaha YMF71x SB Pro Mixer Bug Issue Fix Also, does it have a proper lowpass filter like the SBPro2 CT1600? Since Yamaha YMF71x based cards usually don't have the proper value caps to match the LPF on the CT1600.
