Woodpecker

WoodPecker (http://woodpeckerflash.wordpress.com/) is fun. It is a set of Flash Classes that lets you animate to sound. It gets really interesting when you have full flash scenes and characters that animate to a song as well as along a time line. By animating to a song I'm referring to having the image either scale vertically and proportionally according to the frequency of the beats of a song or multiply and decrease according to the frequency of the beats of a song. There are a few properties that allow you to access the beats, amplitude etc. I managed to make an animation where the main frequency display, after reaching a certain height on the stage, triggered another animation.
