Hi, Thanks for the guru example, I had no porblem getting a 2d transform to work. But I can't get the inverse fft to work. Setting the directionality to (1) instead of (-1) for the forward still results in the forward fft. It seems like the call library node doesn't pass the sign correctly to the fftw dll. Do any of you have advice on how to prperly address the fftw dll to obtain the backward transform? Thanks, Marijn
