Python: Frequency Analysis of Sound Files

Question

I am generating some sound files that play tones at various frequencies with a certain number of harmonics.
Ultimately, these sounds will be played on a device with a small

Answer 1

you can use numpy and matPlotLib. Something like the code below:

spectrum = numpy.fft.fft(signal)
frequencies = numpy.fft.fftfreq(len(spectrum))
pylab.plot(frequencies,spectrum)
pylab.show()

That will show a graph of the fft spectrum.
