title: extract data from .wav file
body: <p>i have <a href="https://drive.google.com/open?id=1A-DO712X2xxoMS7LW6mrE5JGhVhi_yYe" rel="nofollow noreferrer">this</a> .wav file containing an ECG signal , Iwant to extract the data in that file using  <code>scipy.io.wavfile.read('sig100.wav')</code>
  but I got this error </p>
  
  <blockquote>
    <p>"has {}-bit data.".format(bit_depth))</p>
    
    <p>ValueError: Unsupported bit depth: the wav file has 11-bit data.</p>
  </blockquote>
  
  <p>As I was doing some research on this I found out that that function only accepts 8-bit depth file , but I can't figure out how to modify it to accept my file I found <a href="https://stackoverflow.com/questions/40399930/what-does-the-data-returned-by-scipy-io-wavfile-read-mean">this</a> on stackoverflow but didn't get it </p>
