Editing parameters

Parameters can be edited in the viewer. Select the parameter for editing by either double clicking it in the dialog list box, or by selecting Edit selected parameter from the context menu, or pressing the hotkey E. Once in editing mode, you can select the desired editing function from the Edit menu. The following commands are available:

Undo

Undo last edit function. Only one undo step is possible.

Set Zero

Set the bracketed parameter function to zero. This function is useful to clear incorrect parts of f0- or formant tracks.

Set Value

Set the bracketed parameter function to the specified value.

Scale

Multiply the bracketed parameter function with the specified scaling factor.

Shift

Add the specified value to the bracketed parameter function.

Draw Line

Draw a line between the two time cursors. The line replaces the bracketed parameter function.

Join

Join "broken" parts of the parameter function between the time cursors (e.g. to connect broken F0/formant tracks).

Smooth

Apply (3-point average) smoothing to the bracketed parameter function.

Copy, Move

Copy or move the bracketed parameter function to another parameter function of compatible type. A dialog box is displayed to select the target function.

Exchange

Exchange the bracketed parameter function with another parameter function of compatible type. A dialog box is displayed to select the target function.

Mask Out

Use the bracketed part of the current edit function (must be an F0 or formant track) as a mask for all other displayed frequency parameter functions. All parts of the functions where the edit function is zero (broken) are cleared.

Y Range

If checked, also the cursor Y-positions are used for bracketing, otherwise only the cursor X-positions (time) are used.

You can leave the editing mode using the hotkey X or by selecting Leave edit mode from the dialog's context menu.
