I actually thought the same thing myself after hearing the transposed version.
But that is the transposed version (down many octaves).
I doubt any Homo sapiens can snore/whistle at 14Khz. At least that kind of
snoring wouldn't disturb your husband/wife. Might keep the dog awake though.

I was our recording some frogs for the Texas Amphibian Monitoring program last
night and I once again recorded something strange that I have recorded before
on occasion. Once in a while when recordings Anurans at night here in Texas, I
will record a high pitched downward slurring call that is clearly not an
amphibian. It is also not audible to me while recording but shows up clearly
in the spectrogram.
It is usually a series of descending calls somewhere from around 14 Khz down
to about 11 Khz. I don't believe it is an insect because it is too sporadic.
I will only record it once or twice in a 5 minute recording sample at most.
I know the calls of all the local amphibians so I know it isn't that. I am
just wondering if anyone has any ideas what it could be.
You can see the sample spectrograph here

http://www.pbase.com/sandboa/image/152879059.jpg. The frogs are Spotted Chorus
Frogs whose calls are focused around 3Khz. But above this I captured the
descending call.
And in case you wanted to hear it, I brought it down a more audible range of
around 3-4Khz and you can hear that transposed version here -

Anyone have any ideas? Bat?
