title: Playing sounds with python and changing their tone during playback?
body: <p>Is there a way to do this? Also, I need this to work with pygame, since I want audio in my game. I'm asking this because I didn't see any tone change function in pygame.. Anyone knows?</p>
  <h3>Update:</h3>
  <p>I need to do something like the noise of a car accelerating. I don't really know if it is timbre or tone.</p>
