Filter Editing via ”Mouse Movement” in the Graphics Display
A white dot in the frequency response display represents an active filter (BYPASS not engaged). Clicking with the left
mouse button on this dot and keeping the mouse button pressed down allows changing the selected filter’s frequency
by moving the mouse to the left or to the right.
Dynamics (FIR Controller original)
The Dynamics window provides access to a compressor and a Peak Anticipation limiter. This allows setting the
corresponding parameters in a band pass, so that connected loudspeaker systems are protected against dangerous
level peaks and overload.
Click on the fifth block in the Flow Diagram Selector or double click on the DYNAMICS block in the large Flow Diagram
to select the Dynamics window.
