iMovie for Mac: Apply audio effects to clips

Apply audio effects to clips

iMovie includes audio effects that you can apply to clips to enhance the sound in your movies.

Add an audio effect to a clip

  1. In the browser or the timeline, select an audio clip, or a video clip with audio.

  2. To show the effects controls, click the Video and Audio Effects button.

    Video and Audio Effects button in adjustments bar
  3. Click the Audio Effect button, and click the audio effect you want to apply to the clip.

    Audio Effect pop-up menu

To remove an audio effect, select the clip or range containing the effect, click the Audio Effect button, and click None.

Lower the volume of other clips that play at the same time

When you have background sound or other clips with audio playing at the same time as a clip you want to hear in the foreground, you can automatically lower the volume of the other clips so that they don’t compete with the clip you want to hear.

For example, if you record a section of voiceover audio, you can have iMovie lower the volume of background music and other clips while the voiceover clip plays.

  1. In the timeline, select the clip whose audio you want to hear in the foreground.
