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,
Now I'm disappointed ...
though given a bit of study I can probably decode it.
... ah, and relieved a bit again. ;)
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.
The power of Pd of course is, that you can influence things on a much lower level than NI allows you to do in Reaktor - although I admit, that I only know Reaktor from screenshots. The downside is, that you have to dig deeper to make the most out of Pd. This is especially true for FFT applications. The actual FFT patches often are very simple and they contain just of a handful of objects. It's the knowledge hidden inside that makes them difficult to understand.
While you can skip a lot of the math, you cannot do FFT in Pd without at least understanding what kind of data is generated by the two [rfft~] outlets. Because without understanding this, you cannot even "fool around" with the data in between [rfft~] and [rifft~] in a meaningful way.
Anyway, to give you a blackbox maybe like in Reaktor, attached is a Spectral Delay GOP abstraction ready to be dropped into any glitch patch.
