"Noise??"
What I meant about "hiss" in my posting about the coyotes, was typical
electronic noise. As I heard it, I couldn't believe it was hiss from the NT1A.
But here is another "noise" Rich, - lots of atmo noise, broken into pieces
by MP3 and more audible. That is another thing.
As this recording is, I don't hear any electronic noise at all, not even
after I have used a highpass filter, as the average "atmo" noise level is
too high.
