I tried that Levelator program and it seems to be good and bad - it adds a little hiss but clears up a lot of the recording without having to run a high pass filter through it. Plus there was a couple points where it seemed to block the audio out completely. This is going to take a while to get it right...
I might see if I can track another recording device down and see if that improves things.
Anyhoo - here's the latest Wardio episode;
