Sound and Fourier Analysis with MATLAB H. Edward Donley Mathematics Department Indiana University of Pennsylvania Basics of Sound. Pure tone — sine or cosine function frequency determines pitch (440 Hz is an A note) amplitude determines volume. Sampled sound (digital audio) — discrete sequence of intensities CD Audio is 44100 samples per second

matlab-audio-process. Apply Short Time Fourier Transform to audio signal, and apply frequency-domain transform to the signal: Extract four peaks with greatest magnitude. Randomize the phase. To start, edit parameters in script.m and run it. Octave compatible, although it seems octave is much slower than MATLAB (?)
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);

2.3.9 Applying the Fourier Transform in MATLAB. Generally when you work with digital audio, you don’t have to implement your own FFT. Efficient implementations already exist in many programming language libraries. For example, MATLAB has FFT and inverse FFT functions, fft and ifft, respectively. We can use these to experiment and generate ...
