Hello Valerio Riso,
I understand that you want to cut the last 20 seconds of a audio file using MATLAB.
I have written a sample code which will perform the task.
filename='yourfilenamewithextension'
[y, fs]=audioread(filename);
samples=[1,length(y)-(20*fs)];%replace 20 with the number of seconds you need to cut
[y1,fs] = audioread(filename,samples);
audiowrite('cutversion',y1,fs);
You can play around with samples in the code to change the duration of the audio you want to extract.

how can I take only a small portion of the audio signal, about 500 consecutive points, and repeat this portion 10 times using the repmat command?
