Re: Gun Fight: effects of final amplification

Just submitted a PR for my Gun Fight improvements. Took me bloody long enough.
In retrospect, I spent too much time and effort going down the avenue described above. I've pretty much punted the issue, other than explaining it in source comments. What's there already works pretty well. The issue may be worth revisiting later if more detailed info becomes available on Gun Fight's noise generator voltage and how its power amplifiers, speakers, and cabinet behave, together with an infrastructure better able to use such info. But for now, this is good enough.
couriersud's points are valid, but I really didn't intend to get into details of modeling speaker, cabinet, and microphone acoustics. Mostly I was looking for a sanity check on my thoughts.
Also, one needs to be careful modeling circuits in LTspice. Turns out my noise generation was a bit off: it was using a uniform distribution instead of a normal one.
