ManipulationEditor

One of the Editors in Praat, for viewing and manipulating a Manipulation object.

Objects

The editor shows:

Playing

To play (a part of) the resynthesized sound (by any of the methods shown in the Synth menu, like overlap-add and LPC), click on any of the 1 to 8 buttons below and above the drawing area or use the Play commands from the View menu.

To play the original sound instead, use Shift-click.

Pulses

To add:
click at the desired time location, and choose Add pulse at cursor or type Command-p.
To remove:
make a time selection, and choose Remove pulse(s) or type Option-Command-p. If there is no selection, the pulse nearest to the cursor is removed.

Pitch points

To add one at a specified time and frequency:
click at the desired time-frequency location, and choose Add pitch point at cursor or type Command-t.
To add one at a specified time only:
click at the desired time, and choose Add pitch point at time slice. ManipulationEditor tries to compute the frequency from the intervals between the pulses, basically by a median-of-three method.
To remove:
make a time selection, and choose Remove pitch point(s) or type Option-Command-t. If there is no selection, the pitch point nearest to the cursor is removed.
To move some:
make a time selection (the points become red) and Shift-drag the points across the window. You cannot drag them across adjacent points, or below 50 Hz, or above the maximum frequency. You can only drag them horizontally if the dragging strategy is All or Only horizontal, and you can drag them vertically if the dragging strategy is not Only horizontal. You can change the dragging strategy with Set pitch dragging strategy... from the Pitch menu.
To move one:
drag that point across the window. You can only drag it horizontally if the dragging strategy is not Only vertical, and you can drag it vertically if the dragging strategy is not Only horizontal.

Duration points

Work pretty much the same as pitch points.

Stylization

Before editing the Pitch points, you may want to reduce their number by choosing any of the Stylize commands from the Pitch menu.
