title: RuntimeError when reading wav file
body: <p>I am following the <a href="https://github.com/mravanelli/SincNet" rel="nofollow noreferrer">https://github.com/mravanelli/SincNet</a> library . I have followed the documentation as suggested. but I got the RuntimeError</p>
  
  <p>I have changed the file access using <code>sudo chmod +x /home/sathiyakugan/Downloads/TIMIT/data/lisa/data/timit/raw/TIMIT</code> but it didn't solve the problem.</p>
  
  <p>This is the syntax that I executed 
  <code>python3 TIMIT_preparation.py /home/sathiyakugan/Downloads/TIMIT/data/lisa/data/timit/raw/TIMIT /home/sathiyakugan/Documents/FYP/out data_lists/TIMIT_all.scp</code> </p>
  
  <p>and this is the error I received.</p>
  
  <pre><code>  File "TIMIT_preparation.py", line 56, in &lt;module&gt;
