It changes the "Effects" audio track to zero during and for a few seconds after combat.

That's the audio track that includes the death screams. I chose to include combat as well as after combat on the concept that if you're fighting creatures, there's a chance you're fighting more than one of them, so you'll probably have some dying while you continue to fight the others. I suppose that might not be quite as bad, since you'd still have combat sounds going on as well, so might not hear the death screams quite as well.

I've been using this since I released it, and I'm not quite happy with how it performs, so I've been working on improving it. I'll be putting out a new version soon.
