Hi, I am looking for some help.

I have a couple of audio files in a directory.

I extracted a portion of each audio file, and I want to save it into a new audio file.

How do I do it in a loop such that it is saved like in the following examples?

The below is my current code. Could someone vet for me especially the last two lines before end?

Thank you in advance!

Initial Files Extracted New Files

data_1.m4a extractedData_1.m4a

data_2.m4a extractedData_2.m4a

data_3.m4a extractedData_3.m4a

for p = 1:3
startSample = n;
endSample = length(data);
extractedData = data(startSample:endSample);
audiowrite(extractedData_,extractedData,fs);
filename = sprintf('%s%d.mat', extractedData_, p);
end

    filename = fullfile(wor_dir, file_)
    audiowrite(filename, extractedData,fs);
end
