It's not hard to do, but it is time-consuming. As far as I know, you can't do it with the built-in effects. You would need to use Sound Keys to create keyframes for solid layers or shape layers. (Or mess around a LOT in Audition to create a separate sound file at different frequencies for each bar.)
