Mafia 1 - strange reverb feedback loop in some locations

[Lrflx]

During my last playthrough I noticed that in several locations something strange definitely was happening. Easiest to check is in prison tower, with alchemy there's a slight humming trail going on for couple seconds after every gunshot. And with dsoal it just keeps going on and on instead, practically indifinetiley and doesn't stop even in main menu. Tested it with reverb boost setting and it does change reverb in general, but doesn't have any audible effect on that feedback loop humming.

With the last git?

Yes, just did it and same thing is happening there

FWIW, there is newer code in the C++ rewrite branch (although I don't expect EAX/reverb behavior to be much different; and that branch is currently missing a few features like capture/duplex operation and WRITEPRIMARY support, that still need to be reimplemented).

I do need to find some way to log the EAX parameters being set, in a way that doesn't significantly impact performance when not logging. The reverb gain shouldn't be significantly different, nor should the decay tail, so it'd be helpful to see what EAX property values are being set.

Ok, I'll be glad to retest it whenever it comes out. To be honest I'm not sure if it's even a reverb, sounds more like reflections, don't know for sure if EAX 3 can to it.

Are you able to provide a recording of it happening? Preferably of both ALchemy and DSOAL for comparison.

Of course. Some additional clipping got there during capture, it wasn't in game originally
