Hi Marc, 
Great recording by the way. Nice broad spacial qualities on both headphones and 

The specific location setting lends to a low noise feeling: the high frequency 
insect band around 8k creates a strong mask to the mic self-noise in the 
frequencies above.  However, I do not expect this quality will convey in all 
the natural settings you may be interested in recording.

There is a prominent rumble or pulsing down around 50 Hz that I find 
distracting. While checking in mono I hear this problem even more noticeably as 
the in-phase components sum. This could be addressed by basic parametric eq - 
or with MS processing attenuating the Mid component only.

A SASS type array would certainly change the overall dynamics, though I am not 
sure about how it would affect oomph in the mid to low. 

What recorder did you use?
