the actual effect that the notch filter has on the
sound..

mouse button on this dot and keeping the mouse button pressed down allows changing the filter’s frequency by
moving the mouse to the left or to the right. Clicking with the right mouse button on the white dot and keeping the
mouse button pressed down allows changing the Q-values of the filter.
