Abstract:
A method of driving a computer generated animation with an audio signal, with the animation comprising a number of frames rendered sequentially at a frame rate, with each frame for displaying at least a first object, the method comprising the steps of:for a current frame, capturing a frame's worth of said audio signal to obtain a captured segment of the audio signal and extracting an energy characteristic of the captured segment of the audio signal; utilizing the energy characteristic of the captured segment to generate a conditioned control signal having an amplitude which responds rapidly to a rapid increase in magnitude of energy characteristic; when the conditioned control signal amplitude increases rapidly in magnitude, initiating a deformation of the first object to be rendered in the current frame; and delaying the conversion of the captured segment of the audio signal, corresponding to the current frame, into a sound signal until the current frame is rendered and displayed to synchronize the occurrence of increase in magnitude of the energy characteristic to the display of the initiation of the deformation.
