Re: [microsound] talk about supersonic signals and distortion

Starting at a bit rate of 192 and higher, frequencies at and above 19,000
Hz are cut less for mpeg layer 3.  256 seems to be the shoulder of the
curve where values at and above 20,000 Hz recieve a negligible cut. 
Anything significantly higher than 20,000 Hz is cut completely. But what
is the point of using frequencies that high.

Extremely sub-audible tones at high amplitudes can still affect the
listener but, and this is just my opinion, extremely high frequencies just
get lost.

For my ear, the range between 19,000 Hz and 20,500 can still have an
effect and especially when combined with other frequencies to accentuate
and exploit "by-products in the normal audible range created by flawed
filtering in the encoders (or other hardware/software)".

And then, of course, there is always your system which I won't discuss
(gear wars).

Anyone here play with really low freq's?  I haven't had the chance to
experiment with them much.
