Hello,
I found lot of answers, how to cut last 10 sec, oder first 2 sec.
But I do a opposite - I have multiple of .wav-Files 35,36,31,...sec long
I want just to "reshape" a files and have first 30sec.
How it is possible?
I tryed:
[y,fs] = audioread(filename);
filename = '20200605_004200.wav';
y(:,30*fs:end) = [];
wavFileName = '20200605_004200.wav';
audiowrite(wavFileName, y,fs);
But it does not working =)
Thank you in advise!
