[SciPy-user] Create a spectrogram from a waveform

Hello,
I wrote a program in C# that creates a spectrogram from the waveform of a
.wav music file. I now want to port it to Python, and I want to try to use
SciPy instead of a direct port of the existing code, because I am not sure
that it is perfectly accurate, and it is probably slow.
I am having a hard time finding out how to do this with SciPy. With my
code, I had a FFT function that took an array of real and imaginary
components for each sample, and a second function taking both that produced
the amplitude. The FFT function in SciPy just takes one array.
Has anyone done this task in SciPy?
Thanks.
