For a technology project I am attempting to make a sound display system which separates the light into separate sound frequencies and show their amplitude, much like the graphic displays on some hi-fi systems. However I am unable to find a way of separating the sound up into these different bands, I have heard that a certain resistor-capacitor arrangement could do this but have been unable to find any further information on this. Also if there are any sources which could provide this information on the Internet it would be much appreciated.
