I took the new Fusion 10 out for a hike in Yosemite to go up the Nevada Falls trail and see what I could get. The top of the Nevada falls area just sounded as basic as any rushing water river or creek, however down below at the bottom of another waterfall (Vernal Falls), the water slapping the rocks made for a more interesting sound.
I tried finding a quiet area, to get some general ambience of the ambient wilderness, a few bird noises, ravens in the background. I think this situation is where the Oktava’s start to fail with their self noise presence in the recordings. Again, recordings were done at 24 bit / 96k, on the Fusion 10, M/S config using the Oktava MK-012′s.
