unless the prorammers are complete morons these original numbers SHOULD be passed through which should preclude too much artistry in processing the extra points. That's my concern anyway.I agree the 15 number is completely erronious. Usually, the algorythm is Guassian & requires lots of data with a digital time delay. Then, is feedback with digital data to preclude frequencies above &half Nyquist.
However, I think a naturally decaying HF treble note in a busy song has too few points to reconstruct it properly. The answer is less than unique. I think an intelligent Fourier scheme could be employed to determine if its on any other channels. If it is, more points can be used to determine the true nature of the wave. Plus, one could use a naturally decaying curves as the spline routine instead of some mindless parametric schtick. I could be full of it, but would be worth a look.
....just my 2¢
