Animation Challenges
Music driven animation will use loudness, pitch or frequency of a given sound file to control the object's parameter, such as height, size or color.
In the CHOP network, a Pitch node is used to separate the pitches according to frequency from 110Hz ~ 660Hz. To present the waveform on the pin-board, a Shift node is added so that at each point it will has a delaying effect.
