I would agree here.
We also might want to think if we are truly recording what's out there
for people to listen to when we go to great lengths to record these
"noise free" recordings. That's not what they will find if they go out ther=

I consider the stereo parabolic to be the biggest advantage when I moved
from my previous mono parabolic. You then allow people to use the very
best filter of all, their own internal sound processing. Far more
capable than any filter we might apply.
I have a recording where a large truck passed a few feet behind me. It's
stereo, and clearly the truck is not where the frogs are. You can hear
far more of the frogs in that than you would be able to do if it was a
mono parabolic.
So, I read these experiments with a extra mic and don't think in terms
of how to record using one channel for the extra mic and one for the
mono parabolic. I think in terms of how it might be possible to do this
with the two stereo channels coming from the parabolic. Because
switching back to mono would loose more than I might gain.
The use of stereo in nature recording should be considered in our
methods of dealing with noise.
