[PD] is this a spectral gate?

I wish there was an "fft for dumbies" ... or, I guess, some kind of
fft "black boxes" to play with, where you don't need to understand the
math. Frank's recent post completely lost me, though given a bit of
study I can probably decode it.

But, for instance, in Reaktor or Plogue Bidule, you can move stuff
into fft, mess with it, and resynthesize, without having any idea what
the hell the math is. In comparison, I really couldn't understand the
PD fft examples at all, it's just been too many years since I had a
math class. I hope to get back into the math soon and understand at
least enough for the PD fft stuff, but I have a lot of coding and
design work and tracks I have to finish, before I can do that.
