Audio Effects

Use audio effects to enhance or correct audio. There are two ways to work with audio in Camtasia: edit directly on the timeline or add effects.


Add an Audio Effect

  1. Click the Audio Effects tab.
  2. Drag an effect onto an audio clip on the timeline.
    • To view applied effects, click the Show Effects tray icon on the media.
    • To hide applied effects, click the Hide Effects tray icon on the media.
  3. To adjust the duration, drag either end of the effect on the timeline.
  4. To customize the effect, click Properties.
    Some effects have audio points instead of properties which are adjusted by clicking and dragging audio points on the track. See Basic Audio Editing.
