Yeah, I kind of guessed that - although I dont want to do it well, I just
want to do it!
(Im going to try this out anyway, but...) What would happen if I just
resampled the data, and interpolated some samples for the info that i threw
away?
At any rate, I've reserved a couple of DSP books from the library so I'll
get back to you all when I can do Fourier transforms in my sleep!
