MATLAB’s Fourier transform ( fft) returns an array of double complex values (double-precision complex numbers) that represent the magnitudes and phases of the frequency components. fftdata = fft (a); In MATLAB’s workspace window, fftdata values are labeled as type double, giving the impression that they are real numbers, but this is not the case.

The Fourier transform is used to extract amplitudes and frequencies from periodic functions. The Fast Fourier Transform (FFT) extracts amplitudes and frequencies from sampled periodic functions; that is, it is the discrete version of the Fourier transform.

Sound Processing with Short Time Fourier Transform
https://www.numerical-tours.com/matlab/audio_1_processing/
Local Fourier analysis of sound. A sound is a 1D signal that is locally highly oscillating and stationary. A local Fourier analysis is thus usefull to study the property of the sound such as its local amplitude and frequency. First we load a sound, with a slight sub-sampling. n = 1024*16; options.n = n; [x,fs] = load_sound('bird', n);
