Trapcode Sound Keys
Scale will scale all bars in the spectrum uniformly.
Q (smoothness) defines the wideness of the bars' frequency response. A high setting will make the spectrum curve smooth, and a low setting will make it more "jagged."
Sub Base provides scaling for very low-frequency bars (red).
Base provides scaling for low-frequency bars (red-orange).
Mid provides scaling for mid-frequency bars (green).
Treble provides scaling for high-frequency bars (blue).
