title: Numpy fft.pack vs FFTW vs Implement DFT on your own
body: <p>I am currently need to run FFT on 1024 sample points signal.  So far I have implementing my own DFT algorithm in python, but it is very slow. If I use the NUMPY fftpack, or even move to C++ and use FFTW, do you guys think it would be better?</p>
