First of all, let us please get the name correct, our company is named Wild=
tronics, not Wildtronic. =0D

David, some of our samples were directly recorded with a DSLR camera and no=
t an external recorder that had more controls. A couple of birds may have p=
eaked because the DSLR's gain couldn't be turned down enough because the mi=
crophone responded so well to a distant bird. The only processing we did wa=
s a low cut filter (200hz), and level normalization. These are demonstratio=
n videos/sounds to show how well the parabolic microphone picks up sounds a=
t a given distance and it's general frequency response and are are not inte=
nded for scientific analysis. They are also not intended to be perfect reco=
rdings of said species.=0D

We stand by our specifications. We quote that the 4dB noise is an equivalen=
cy. To match the signal to noise performance of our dish microphone system,=
you would need to place a 4dB microphone into a standard, 22 inch or so, p=
arabolic dish. We list our specifications, what other listed specifications=
are you comparing them to?=0D
=0D
The best way to do a comparative test would be to place a signal source, of=
fixed different frequencies, at 50-100 feet, record from both units, and m=
easure signal to noise ratio on an analyzer. Make sure both dishes are perf=
ectly focused, not saturating, using a very low noise recorder in a very qu=
iet environment.=0D

David, I will give your peanut can idea a try when I get a chance on both o=
ur mono dish and on our stereo microphones. I have been busy making a numbe=
r of options to further improve the microphones. It should be noted that ou=
r stereo microphones are on separate channels than the mono channel, three =
channels in total on our mono-stereo microphone. Our amplified mono-stereo =
unit has a built-in mixer to combine the channels in any proportion. =0D

If anyone has questions, I would be happy to answer them.=0D
