Sound Files in MATLAB — MATLAB Number ONE
https://matlab1.com/sound-files-matlab/
MATLAB has several MAT-files that store for various sounds the signal vector in a variable y and the frequency in a variable Fs. These MAT-files include chirp, gong, laughter, splat, train, and handel. There is a built-in function, sound, that will send a sound signal to an output device such as speakers. The function call:
2.3.3 Modeling Sound in MATLAB – Digital Sound & Music
http://digitalsoundandmusic.com/2-3-3-modeling-sound-in-matlab/
2.3.3 Modeling Sound in MATLAB. It’s easy to model and manipulate sound waves in MATLAB, a mathematical modeling program. If you learn just a few of MATLAB’s built-in functions, you can create sine waves that represent sounds of different frequencies, add them, plot the graphs, and listen to the resulting sounds.
