Abstract

A method and system to drive transformations of a visual representation, in real-time, that synchronizes the audio and visual outputs and controls the magnitude of object deformation to be visual pleasing. In one embodiment, sudden increases in the spectral energy are detected to time the initialization of deformations and a smoothed signal is derived from the time varying spectral energy curve to control the magnitude of the deformations.
