Editing the Filter Curve

By adding nodes and moving them, you can create your own filter curves.

Choices

To add a node, double-click in the graphical display.
To remove a node, double-click it.
To move a node, drag it to another position.

Note
If multiple nodes are selected, they are moved together.
To change the frequency of a node, select it, and enter a new value in the Frequency field.

This is the same as dragging the node horizontally.

Note
If multiple nodes are selected, they are moved relative to each other, that is, the distances between the nodes are maintained.
To change the gain of a node, select it, and enter a new value in the Gain field.

This is the same as dragging the node vertically.

Note
If multiple nodes are selected, they are set to the same gain.
To copy one or several nodes, select the nodes, open the context menu, and select Copy.

To paste the nodes from the clipboard, click at the position where you want to insert the nodes, open the context menu, and select Paste.

To replace nodes with the nodes copied to the clipboard, select the nodes that you want to replace, open the context menu, and select Replace.
To flip the Gain values of the nodes around the vertical center of the selection, open the context menu, and select Invert Gains.
To flip the nodes around the horizontal center of the selection, open the context menu, and select Invert Frequencies.
