Hi David--
The vertical axis imaging in my headphones is especially stunning.
The flutter in the reverb at the very first of the thunder seems to
be coming from above as well. As flutter usually occurs between two
(or more) roughly parallel reflecting surfaces, this has me curious.
Perhaps there are two parallel cloud shapes overhead or maybe the
flutter is happening between the land and the clouds if the clouds
are very low.
Can you describe the lie of the land with a little more detail? Are
you on a plateau above the canyon or within the canyon? It could be
that the gain is so low that the most distant reflections are buried
by contrast. Based on the spatial cues I can detect, they suggest to
my ears that the mics are not within a canyon unless its a narrow one
(well less than 200 meters). I think I might detect a ground-level
vertical surface towards left center about 150 feet away and an
"opening" that extends away in the rear, moving a little to the
right. If so, that surface on the left and the ground might be
involved with the flutter. Thanks for sharing! Rob D.
