Rich,
Now that is really cool! Is there a particular reason
why the recording is sampled at 22050 Hz? It seems
like a lot of the sound is right at the upper band
edge? I do have the impression, as you apparently did
too, that the piezo device has a non-uniform frequency
response. Why not make the recording with a
conventional microphone?
I did something a little like this back in the early
70s, when one of my professors asked me to make a
recording of a Drosophila mating dance. I made a
little jar to hold the fruit flies, where the entire
bottom of the jar was a condensor microphone. the
project wasn't too successful though. The only sound
I managed to record during my short project was the
sound the flies made while escaping the jar...
Perhaps I'll try to make such a recording using a very
quiet Rode NT-1A...
