Fast Fourier Transform (FFT) in C#
Is there a good open source library of source code listing that will perform FFT, preferably in C#. I am being given an input waveform as an array of float values and would be calculating the functions based upon that input. Any assistance would be greatly appreciated.
Thanks.
Thanks.
