Which is pretty much exactly what I did.  I used WaveARTs MRNoise for this
purpose, I have access to Izotope RX2 as well, but given that the signal
there is so weak, I didn't use that in a destructive manner, and I am
finding I prefer wavearts for primarily high frequency noise.  However
since RX2 is a new acquisition for me I am still learning their strengths
and weaknesses.

Heh it is very interesting to hear you describe it, as I didn't look at the
signal analysis at all when I did mine, but also put in a fairly sharp
lowpass filter at 12k as I didn't hear anything usable above that when I
boosted.  Now I am curious to go back and try out what you describe as well
as look at the statistical analysis and see if it can be improved a bit
more or not, I just don't have time these days sadly.  This was a quick 15
minute project or so to see what I could do out of my own curiosity while I
had some spare time before a meeting.
