Ah, forgot to actually cite one thing:

I can't find its' implementation in anywhere so that I can't understand what happen in this function.
A DFT is performed, by calling the fftwf_execute function of the FFTw library, which really, just executes a fast DFT.
And because "DFT" is not totally unambiguous (because there are different normalization conventions out there), if you care for the actual formula, it's  on
i.e. the backwards (inverse) n-point FFT is really just plain, old, boring, textbook

No normalization.
