Create a WAVE file from the example file handel.mat, and read the file back into MATLAB®. Create a WAVE ( .wav) file in the current folder. load handel.mat filename = 'handel.wav' ; audiowrite (filename,y,Fs); clear y Fs. Read the data back into MATLAB using audioread. [y,Fs] = audioread ( 'handel.wav' ); Play the audio.

Create an audioplayer object, then call methods to play the audio. For example, listen to the gong sample file: load gong.mat; gong = audioplayer (y, Fs); play (gong); For an additional example, see Record or Play Audio within a Function. If you do not specify the sample rate, sound plays back at …
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: >> sound (y, Fs)

To play an audio file in MatLab you use the sound() function. The following function plays the sound. If the Fs variable is not defined or included in the command, it will assume the default sample rate of 8192 Hz. sound(y,Fs); Section 3: Audio Scaling To scale an audio file the soundsc() command is used. This allows for the

https://dsp.stackexchange.com/questions/40871/filtering-an-audio-file-in-matlab
I am trying to process an audio file in Matlab by filtering out all frequencies except those within $\pm 25\ Hz$ of $523\ Hz$ (as well as its harmonics up to the Nyquist). The resulting waveform should look like the green wave displayed below (blue being the original): However, my resulting waveform is entirely zero: Here is the simple code I ...
