QuiFFT: Amazingly simple Fourier transforms in Java

https://www.quifft.org/

FFT computation in Java incredibly easy. QuiFFT abstracts away the technical details of digital audio representation and wave mathematics, providing a delightfully simple interface for computing Fourier transforms in Java. Your first FFT can be as simple as one line: FFTResult fft = new QuiFFT("audio.mp3").fullFFT();

The "Fast Fourier Transform" (FFT) is an important measurement method in science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems. This article explains how an FFT works, the …
