![]() The green curve usually follows the blue curve closely, but will be forced to a smoother path if there are sudden changes in amplitude over a small frequency range. The green curve is the one that Audacity actually uses to perform the effect, taking into account the limitations of the equalization algorithm. To remove a control point, drag it outside the graph. Doing either creates a control point at that position, then creating further control points draws the curve. ![]() ![]() The blue curve is drawn by either clicking in the graph at any position, or clicking on the blue curve and dragging it to a position. The white circles are called "control points". ![]() Equalization Curves and Control Points: If you look closely at the curve in the image above, you will see it is composed of a blue curve joining together a number of white circles, and a green curve which follows the general shape of the blue curve. ![]()
