Fast Fourier Transform

Fast Fourier Transform (FFT) performs a multidimensional FFT on the input object specified by Input File. FFT is based on the FFTW 3 library (see www.fftw.org).

Before using these methods, like other frequency processing methods, ImGearFrequencyProcessing.InitializeFFTW Method() must be called first to enable support for FFTW.
