[PD] FFT question

[Thurstan]

I have a question about the FFT blocks. Is there a way to input
spectrum-information in stead of time-based information?

To put it differently: If you put in a sine wave it will be analised and
output like a sine wave. The spectrum will contain
one bin. I would like to insert a pulse that would be analised in the window
and outputted as if it were a bin.
So when you delay the pulse with a feedbackdelay one will hear some kind of
grain pattern consisting of little windowed sine components.

I hope my question makes sense ;)
