title: Animate object to move based on modulation of a sound?
body: <p>I am trying to animate an object (mouth, eyebrow and some other expressions) to move in accordance to incoming sound. I was thinking to read sound modulation and detect changes and to animate movement of objects.</p>
  
  <p>Is this a good approach?</p>
  
  <p>If not, how should I approach to coding such feature? Does this have to be done in OpenGL or I can use Android SDK and its animations?</p>
