Hi John, all...
"in my humble experience"
During the 25 years of Telinga, no scientist that I know of has
failed doing his research because he has used a Stereo DATmic instead
of a Twin Science.
Using mono, I have several times been able to hear two different
sounds from the same spot. Is it the same bird, making both sounds,
or two different birds sitting very close??
At a few occasions, using stereo, it has been possible to hear or
analyze with a PC if it is, or is not, the same bird.
My general recommendation is that you use a Twin Science if your
recordings mainly are for film-tracks or science. If you want your
recordings to trigger your fantasy - "remember and get back at the
spot" - use stereo.
My memory is very auditive: If I replay a recording made in stereo,
it might be a very old recording, it brings back most of the
sensations, even smells. It is like going back in time.
It is also my experience that "common" people tend to bright up and
smile when they hear bird song in stereo headphones, - "very
beautiful!" - while they look a bit worried when the same sound comes
into both ears, as if they didn't really know what to listen for.
It is correct, though, to say that "in theory" a mono parabolic
recording made with an omni is more "accurate".
I say "in theory" as you get sooo many errors anyway, when you make
long distance recordings.
When people are doing science based on freq. analysis, I always tell
to double and tripple check what they are doing.
