title: Analysing audio data for attributes at time intervals
body: <p>I've been wanting to play around with audio parsing for a while now but I haven't really been able to find the correct library for what I want to do. </p>
  
  <p>I basically just want to parse through a sound file and get amplitudes/frequencies and other relevant information at certain times during the song (like every 10 ms or so) so I can graph the data for example where the song speeds up a lot and where it gets really loud. </p>
  
  <p>I've looked at OpenAL quite a bit but it doesn't look like it provides this ability, other than that I have not had much luck with finding out where to start. If anyone has done this or used a library which can do this a point in the right direction would be greatly appreciated. Thanks!</p>
