body: <p>I want to read the left and rigth channel.</p>
  
  <pre><code> import wave
   origAudio = wave.open("6980.wav","r")
   frameRate = origAudio.getframerate()
   nChannels = origAudio.getnchannels()
   sampWidth = origAudio.getsampwidth()
   nbframe=origAudio.getnframes()
   da = np.fromstring(origAudio.readframes(48000), dtype=np.int16)
   origAudio.getparams()
  </code></pre>
  
  <p>the parametre</p>
  
  <pre><code>  (2, 3, 48000, 2883584, 'NONE', 'not compressed')
