title: c++ FFT Beat detection library?
body: <p>I am currently looking around for a good allround beat detection library / source code in C++ since I found it really hard to achieve satisfying results with the beat detection code I wrote myself using this tutorial:
  <a href="http://www.gamedev.net/reference/programming/features/beatdetection/" rel="noreferrer">http://www.gamedev.net/reference/programming/features/beatdetection/</a></p>
  
  <p>It's especially really hard if you want to make it work with any kind of music so I was wondering if there is something usable out there allready?</p>
  
  <p>Thanks!</p>
