After you’ve arranged your audio clips in the timeline, you can fine-tune volume levels, fade the audio in or out, and even change the speed of your clips.

Adjust volume

1. In the iMovie app on your iPhone, open a movie project.

2. Tap a clip in the timeline to reveal the inspector at the bottom of the screen.

3. Tap the Audio button .

4. Do any of the following:

   • Turn sound off or on for a clip: Tap the Mute button next to the volume slider. When the clip is muted, tap the Mute button again to turn sound on.

     When you turn off the sound for a video clip, a mute icon also appears in the upper-left corner of the clip in the timeline.

     

   • Adjust volume: Drag the volume slider left or right.

     To make sure that the sound in your video clips can be heard over the background music, iMovie applies audio “ducking” to background music. Ducking lowers the volume of background music clips whenever there’s a video clip whose sound is playing at the same time. When a video clip’s sound is off, ducking isn’t applied.

5. Tap outside the inspector to close it.

Fade audio in or out

You can quickly add fade-ins and fade-outs to audio clips in the timeline using fade handles.

Fades appear as shaded areas in the clip to show where the volume increases or decreases.

If you have a video clip with audio, you must first detach the audio as a separate clip in order to create fade-ins or fade-outs. See Edit audio clips in iMovie on iPhone.

1. In the iMovie app on your iPhone, open a movie project.

2. Tap an audio clip in the timeline to reveal the inspector at the bottom of the screen.

3. Tap the Audio button .

4. Tap Fade to reveal fade handles at the beginning and end of your clip.

   

5. Drag the fade handles to set the duration of the fade-in and fade-out.

Adjust speed

You can adjust the speed of audio clips in iMovie. You can even fine-tune speed adjustments for a single clip by dividing it into ranges, each with its own speed. For example, you could set multiple ranges so that a clip slows down, speeds up, and then slows down again.

Note: You can’t adjust the speed of a soundtrack or theme music track added from the Soundtracks menu. See
