Waveforms

iMovie HD has added waveforms to audio clips so you can see the peaks and valleys in the sound making it easier to line up a song or sound clip to match action in a video. Waveforms can only be viewed on audio clips, not video clips.

Note: If you want to see waveforms for audio of a video clip, you must extract the audio first.

  1. From the View menu choose Show Audio Waveforms.
