title: What is returned by wave.readframes?
body: <p>I assign a value to a variable <code>x</code> in the following way:</p>
  
  <pre><code>import wave
  w = wave.open('/usr/share/sounds/ekiga/voicemail.wav', 'r')
  x = w.readframes(1)
  </code></pre>
  
  <p>When I type x I get:</p>
  
  <pre><code>'\x1e\x00'
  </code></pre>
  
  <p>So <code>x</code> got a value. But what is that? Is it hexadecimal? <code>type(x)</code> and <code>type(x[0])</code> tell me that <code>x</code> and <code>x[0]</code> a strings. Can anybody tell me how should I interpret this strings? Can I transform them into integer?</p>
