Thanks Peter and Max for those tips,
yes I meant anthrophony (haha--oops!).
At this point I believe we would be interested in looking for (and yearly m=
onitoring of) diversity of sounds (especially wildlife), density (perhaps b=
y volume of sound or number of calls over a specified amount of time), and =
as needed, how traffic or human made noise may interfere with local wildlif=
e. And just create some recordings that can be used as reference in the fu=
ture. This spring we recorded the frogs present at one of the ponds (later=
identified Spring Peepers, Bullfrogs, Chorus Frog, and Green Frog and a ye=
t identified bird). (Eventually hope to invest in some weatherproof recor=
ders and mics to leave out in these area too). So, spectrogram software t=
hat can best help in these sorts of areas is what I am searching for. I w=
ill check out Audacity and Sonic Visualizer.
