They speak of calls of 18 hz.  I asked and didn't get a response on
if the grouse I recorded with a signature to 1/2 hz was accurate.
I have now asked Adobe if the spectral display is correct.
Maybe they (wcs.org) are speaking of voice calls at 18 hz but if so I
don't understand the body mechanics of that. The lowest I have in
voice recorded to date is the Great Gray Owl.
