title: How to read a ".wav" file into MATLAB?
body: <p>I wanted to input a wave file in the MATLAB so that I could process it using filters, when I come to input the wave file called <code>wave.wav</code>, this file is located on my desktop, and then I used </p>
  
  <pre><code>[y, fs, nb] = wavread('wave.wav');
  </code></pre>
  
  <p>to read the wave file but always gives me an error <code>cannot open file</code>, the only thing I can think of is that the function doesnt know the path of the <code>wave.wav</code>, any help?
  And how can I play the file also using MATLAB after read, <code>sound()</code>?</p>
