title: Create 30 second preview of an MP3 file
body: <p>I'm looking for a way of automatically creating a 30 second preview file of an MP3 when it is uploaded through my ASP.NET Web Application.</p>
  
  <p>I want this to work similar to <a href="http://last.fm" rel="nofollow">last.fm</a> or iTunes where you can preview a 30 second clip of an MP3 file before purchasing and downloading the entire song.</p>
  
  <p>How can I achieve this?</p>
