Sorry to pick on you, but this is the piece of
audio voodoo that irks me
most of all. There is no evidence I'm aware of that supports the idea that
ultrasound has any effect whatsoever on human perception of anything.
I am not into that field of science but as far as I know there is research in
that there are effects when >22kHz frequencies are in a normal sound, it makes
a different effect then when the signal is clipped frequency-wise at 22kHz.
Difference between a violin played inside the room you are and a violin-
recording you hear from CD.
But I don't actually know if that is proven enough or if its voodoo...
The violin likely sounds different than speakers, but I guess it's
more likely due to its radiation pattern and things like that which are,
I guess, very hard to capture and reproduce accurately. Just a thought.
