title: Sound Analysis Libraries?
body: <p>I'm interested in learning about audio visualization with shaders. I want to make an application that can do visualizations from audio.</p>
  
  <p>I'm looking for a library that can give me data about the audio that might be useful for visualization.Is anyone aware of any c / c++ libraries that can give me this kind of information? (Maybe the peaks and troughs, or frequencies, etc).</p>
  
  <p>Thanks</p>
