title: Bpm audio detection Library
body: <p>I'm looking for a library that simplify tempo/bpm audio detection.</p>
  
  <p>Something similar to this <a href="http://adionsoft.net/bpm/" rel="noreferrer">http://adionsoft.net/bpm/</a> , but to use on *NIX machines.</p>
  
  <p>Any language, but preference goes to php, perl, python.</p>
