Hi folks, do any of you have a decent book/article reference that contains a practical explanation of using the Fourier transform to obtain a frequency spectra from a sampled audio waveform - with code if possible - that doesn’t go overboard with masses of EE-graduate-level maths? Some maths is fine. Thanks!

@M0CUV https://pysdr.org is your friend.

Yes, it's , but calling an fft routine via numpy is not so different from calling an fft from other languages and libraries.

Also, try out some of the tutorials.

@realn2s Also note:

At this time these two topics have more than the expected in common:

  • Artificial Intelligence
  • Natural Stupidity

These things are quite different:

  • Virtual Reality
  • Real Virtue
