So it doesn't work. I mean, I understand, with a rectangular window there are discontinuities that read as crazy frequencies, but essentially this doesn't work for supplying the imaginary part. I guess it's just academic now, but I'm still curious.
I'm not used to analysis of a spectrum by looking at its real and imaginary parts. Usually, I analyse the amplitude and phase of a spectrum. Thus, can you tell me what do you want to analyze and what "doesn't work"?
br, Piotr
To supply the missing imaginary part to a real signal. It doesn't work to merely put the result of rfft~ into ifft~, either directly or with zeros for the imaginary part, in a 64 sample block size. Now that I think of it, if the signal is recorded, using an astronomically large window size would seem to do it. I wonder what Pd's limitations are.
