	A sound that goes up in pitch for 1/2 hour is possible.  The human
ear has an amazing capacity to detect subtle changes in pitch.  I have
played around a bit, and gotten tones starting a reletively high(10Khz?)
frequencies to go up in pitch for 3+ minutes.  My guess is that they really
just started at a very low frequency and went up to a very high frequency
at some slow rate.  If anyone has a bent for such things you can compute
the 20hz-20Khz hearing range, into delta-hz/sec, and figure out from some
source if the human ear could detect this slow of a change.  On the other
hand, I might not know what the heck I am talking about.
