Drawing Waveforms

You can manually draw waveforms to remove clicks or other unwanted elements.

We generally recommend to use the AudioFill tool from the Enhancement menu to manually remove clicks, but freehand drawing could be a last resort if the automatic interpolation doesn't work as expected.

To enable the draw waveform mode, please click the pencil button in the toolbar as indicated below:

Draw Waveform Button

Click the Pencil icon to toggle the waveform drawing mode. Alternatively, press Shift + D.

Waveform drawing is only possible when you have zoomed in on a very short time period so that the waveform is clearly visible. The mouse cursor changes from a prohibition sign to a pencil when you have zoomed in sufficiently.

For information on zooming in and out, see Zooming and Scrolling.

How to Draw Waveforms Manually

  • Select the Draw Waveform mode by clicking the Pencil icon in the toolbar shown above.

  • Zoom in on the anomaly that you want to correct until the mouse cursor switches to a pencil.

  • Click the waveform and keep the mouse button pressed while drawing the waveform shape.

  • Release the mouse button when done.

  • Play the region to check your changes. See Playing a recording for more information on how to do so.
