I'm just wondering how my adlib emulation matches up against Dosbox, fake86 and a real Adlib sound card. I notice that it seems to sound closer than fake86's adlib emulation. I don't know about Dosbox and a real adlib card though. Anyone?

I don't have a real Adlib card but I have some SoundBlaster with same OPL2 chipset. I know that they are different in the analog path, an Adlib has a proper DAC reconstruction filter while most other cards and all emulations simply omit any filtering.

It appears fake86 adlib emulation (in sourceforge) has less features than x86emu (only registers sets 0x60, 0xA0, 0xB0 and 0xE0), not even 2-op FM.

DosBox is very accurate, it tries to calculate waveforms like the real chip does, instead of using floating point calculations, sin() functions and multiplications.

I mean how does it sound compared to Dosbox, a real adlib and other emulators emulating the Adlib or compatibles? Dosbox probably sounds a little better because it's also emulating various effects still unimplemented in my emulator (AM modulation, Vibrato, Drums, KSR, Scaling level according to http://www.shipbrook.net/jeff/sb.html ). So how does my emulator sound compared to Dosbox and other emulators (just how it sounds to the ears, not how (in)accurate it is when looking at how sound is generated).
