The Pencil Tool

From the Edit menu, choose Tool, and then choose Pencil from the submenu to select the Pencil tool.

Use the Pencil tool to edit the waveform by drawing on it. For example, if you have a glitch in the sound data, zoom in to the glitch and smoothly redraw the waveform.

TIP While holding down the left mouse button, you can also use the arrow keys to fine tune the pencil position.

The Pencil tool is available only at magnification levels below the Pencil tool maximum zoom ratio setting on the Editing tab in the Preferences dialog.
