So basically, in most of the "simple" fft software, they split the signal into freq and amplitude. You can see in the screenshot this is represented by yellow and orange connectors, and they have specific objects so you can play with a whole bunch of crazy transformations on both freq and amp, and then you can resynthesize it back with an inverse fft module.
Yes, the same principle is in use in Pd as well, only that instead of phase and amplitude (often also called "magnitude") you get "real" and "imaginary" data in Pd. But this is only a different point of view on the same thing: one is a "rectangular" view the other is "polar". But you can convert between both views back and forth. The DSP-Guide has a nicer explanation of the conversion: http://www.dspguide.com/ch8/8.htm
what is the advantage of spitting out these values in polar coords?
