Hello, everyone.
I performed audio processing on a .wav file and I would like to know if it was possible to extract this modified file.
If anyone has an idea that would be cool :)

Hey Bastien !
If by extract you mean to save the modified audio signal from MATLAB then use audiowrite(filename,y,Fs). This function writes a matrix of audio data, y, with sample rate Fs to a file called filename. The filename input also specifies the output file format. The output data type depends on the output file format and the data type of the audio data, y.
A reference to help you -
Create a WAVE file from the example file handel.mat, and read the file back into MATLAB.
Write 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(filename);
Listen to the audio : sound(y,Fs);
Hope this helps. Happy Matlabbing !
