The Fourier transform is a powerful tool for analyzing signals and is used in everything from audio processing to image compression. SciPy provides a mature implementation in its scipy.fft module, and in this tutorial, you’ll learn how to use it.

The scipy.fft module may look intimidating at first since there are many functions, often with similar names, and the documentation uses a lot of technical terms without explanation. The good news is that you only need to understand a few core concepts to start using the module.
