Larry, I'll check about sharing the bat sounds.  They were recorded in
conjunction with a sound research project and I was asked to record the
sounds.  I'll see if they will let me share them.

That does sound interesting.  Is that something you can share with us?

Dan, you hit the bottle right on the cork.  Oh Dear.  The limiting
factore is the speaker headphone technology.  I have mikes that will
record to 40 kHz, but can I hear it.  Well, yes and know.  You can
certainly hear more of the upper overtones of a sound which give it its
character, but I can't hear to 40 kHz anyway.  However, I have done some
rather interesting experiments with these mikes.  I recorded a bat and
slowed down the sound.  Of course, now you have totally changed the
sound, but it certainly proved that the mikes were recording that high
in the first place, and the sound was quite interesting.

Fair question.  You hear more than you hear.  By this, I mean you sense

sounds that are not heard as actual sounds.  The ear can actually tune
sounds upwards of 40 khz, but the brain does not sense them as sound,
rather, as presence.  This is why much live music does not sound good on
inexpensive stereo but can sound wonderful if everything in the chain
the original recording microphones to your speakers are capable of 
reproducing an extended frequency range.  True, this is not common, but
have heard it.

It also explains why there is no such thing as a recording that is as
as hearing the music live.  Actually, there are a number of issues
but frequency response of the equipment used is part of it.

The recorders that Neal and I use are capable of recording to 40k, so 
recording with those new mikes would be most interesting if you could
them back through a system capable of producing those tones.  Most amps
capable, the problem lies in the interconnects and speakers. 
cd does not go that high, they cannot reproduce sounds higher than
