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. [-----------------------------------------------------------------------] [ Michael J.
