Testing the Stillwell "Master Tom" compressor on the Ultima Underworld 1 OPL soundtrack, heavily overdriven by +24 dB. Kind of a worst-case scenario, normal people shouldn't really do this, but...

The settings I used for reference (threshold is 0dB because I overloaded the float mixbuffer, so sample values were well over the "nominal 0dB" limit). 

> Very nice find! I haven't even heard of this programming language, let alone the compressor 😆 Yeah, I think nowadays it gets referred to as JSFX; apparently they "rebranded"...

For what it's worth, I'm using [crt-caligari](https://github.com/tyrells/dosbox-svn-shaders/blob/master/crt/crt-caligari.glsl) to emulate scalines in 320x200 EGA games, and a tweaked version of [crt-aperture](https://github.com/tyrells/dosbox-svn-shaders/blob/master/crt/crt-aperture.glsl) for subtle scanlines at 640x350 resolution. By the way, Guest's...

For reference, I've found the holy-grail (to my eyes) of (S)VGA CRT emulation: https://forums.libretro.com/t/new-crt-shader-from-guest-crt-guest-advanced-updates/25444/48 I think it looks spectacular, it has just the right amount of subtle detail. It really...

Thanks @kcgen for the encouraging words and the tips, they're super useful! Some of that advice could be incorporated into a general FAQ if that hasn't already happened (I'm thinking...

> Here's an example: some soundcards had low quality circuitry which introduced a constant hiss into the audio output. If someone authored a hiss-PR, Staging approach would say that the...

By the way, here's a video that demonstrates adding reverb and chorus to OPL music through the AWE64 DSP on real hardware. https://www.youtube.com/watch?v=6oSnhqMsmWM

> First I've heard those added to DOS synth music; and wow! The combination pops the music from its simple "2D" form into a much more complex and realistic sounding...

Hi @joncampbell123, thanks for stopping by. Yes I've had a look at that code, and filtering "on load" in `AddSamples` is a good idea, I'll copy that approach. Other things,...
