QuiFFT

QuiFFT is a Fourier transform (FFT) library for digital audio files.

It aims to abstract away the technical details of digital audio representation and wave mathematics by providing a simple interface for computing Fourier transforms.

If this is your first time using QuiFFT, you'll want to start by looking at the org.quifft.QuiFFT class. For more accessible documentation and code examples, take a look at the project's README.
