QuiFFT: Amazingly simple Fourier transforms in Java
FFT computation in Java incredibly easy. See the docs Code examples 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();
