Animations of audio-related topics for educational purposes

Feel free to use these animations (unmodified, please...) in your own website or lectures. They're animated GIF's, so dragging-and-dropping to your local desktop should work. Also note that the actual graphics are 1200 x 900 pixels, so they're bigger than they look here...
