Hello, I'm new to numpy, and I'm a stuck on my first real project with it.
I am trying to take the rfft of a numpy array, like this: >>> my_rfft = numpy.fft.rfft(my_numpy_array) and replace the amplitudes that can be obtained with: >>> my_amplitudes = numpy.abs(my_rfft) with amplitudes from an arbitrary numpy array's rFFT, which is to then be converted back using numpy.fft.irfft . Alternately, some future plans will involve having to modify individual array element amplitudes directly based on other parameters. I would think that modifying and re-synthesizing signals using FFT is a fairly common use-case, but my attempts at Googling example code have been fruitless. I'm not sure if my rudimentary knowledge of FFT is failing me, or if I'm just not understanding how numpy represents and exposes the data, but I would really appreciate any help I can get :) /carl/
