Re: Nature loops
Thanks Andy for the input.
I tried a recording with a mic in the direction of traffic and one in the
opposite direction and it seems like there's a huge hump of energy with a
peak around 1700Hz. It's mostly crickets and frogs. I tried using
but I may look in cool edit as well to see how it looks.
