title: beep sound in python audiolab
body: <p>How do i generate a gentle "beep" sound in python <a href="http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/audiolab/sphinx/index.html" rel="nofollow noreferrer">audiolab</a>, without the use of external .wav files? I found the following example to generate random noise:</p>
  
  <pre><code>play(0.05 * np.random.randn(2, 48000))
  </code></pre>
  
  <p>Unfortunately i do not have enough knowledge of audio representations to create a beep (of a certain frequency) and i have no idea where to find some understandable documentation.</p>
  
  <p>Any help on this would really be appreciated!</p>
