"I see a voice," Shakespeare wrote. (Yes, he did.
A Midsummer Night's
Dream.) Now you can, too -- see a voice, that is. What's more,
you can see it rolling along the waterfalls of time, in moving hues, from
many angles. You can even see some of the information your computer gets
from it, and have the computer mimic or modify it, using classic digital
signal processing algorithms. Useful for screaming kids, educators, home
entertainment, sound visualization.
