Same kind of thing when you make a color organ, except its position. Intensity
is brightness
or perhaps the rate of enertia of motion.
Position is also a factor in light. The basic low frequency beat creates
jumpy motion. Frequency can be converted to position. Descrete filters
were orginally used to decode music. CPU processing can do it
now.
