Truncating wav files

I'm new to matlab and just started working with .wav files. I am using the following code to read in and plot a file: [x,fs,k] = wavread('music.wav'); x = x(1:length(x),1); N = length(x); time = [0:1:N - 1]*1/fs; plot(time,x)

I am trying to truncate this down to a 1 second clip. How do I do this? Much thanks for any help!

Truncate the wav after 1 sec after the n'th sample:

[x,fs,k] = wavread('music.wav');
y = x(n:n+fs-1, :)

if true
  [x,fs]=audioread('C:\Users\Satyam\Downloads\Music\record20171119115236.wav');
z=zeros(fs*3,40); % for 3 second audio file
h=1;
for j=1:40;
  for i=1:(fs*3);
      z(i,j)=x(h);
      h=h+1;
  end
end
end
