Hi Monika,

Hope this sorts your problem.

    [y,fs] = audioread('filename.mp3');
    info =audioinfo('filename.mp3');
    
    sample_every=2;
    dur=round(info.Duration);
    trimmed=[[]]
    for i=0:2*sample_every:dur
        if(i==0)
            trimmed =[trimmed;y(1:min(dur*fs,sample_every*fs),:)];
        else
            trimmed =[trimmed;y(i*fs:min(dur*fs,(i+sample_every)*fs),:)];
        end
    end
    sound(trimmed,fs);
    audiowrite("trimmed.wav",trimmed,fs);
