iMove is a powerful video editor for Mac computers. Before you start, and especially before producing your video, read some tips on the best way to edit audio in iMovie.
The screenshots and explanations below are for iMovie 10 only, but you can customize the display to make it work in older versions.
Use waveforms to see what you hear
Viewing clip waveforms in iMovie makes audio editing easier.
Sound is just as important as images in a video and should receive just as much attention when editing. To mount the sound properly you need a good set of speakers and headphones to hear the sound but you also need to be able to see the sound.
You can see the audio in iMovie by looking at the waveforms for each clip. If waveforms are not visible, move to Page See drop down menu and select View Waveforms. For an even better view, you can also adjust the clip size for your project, making each video clip and its corresponding audio larger and easier to see.
Waveforms show you the volume of a clip and give you a good idea of which parts need to be turned up or down before you even start listening. You can also see how the levels of different clips compare to each other.
audio settings
Adjust audio in iMovie to change volume, balance tones, reduce noise, or add effects.
With the To adjust At the top right you can access some basic audio editing tools to change the volume of your selected clip or the relative volume of other clips in the project.
The audio adjustment window also offers basic noise reduction and audio equalization tools, as well as a range of effects – from robot to echo – that will transform how people relate to your video audio. .
Edit audio with the timeline
By working with clips directly in the timeline, you can adjust volume and fade audio in and out.
iMovie lets you adjust the audio in the clips yourself. Each clip has a volume bar that can be dragged up and down to increase or decrease the audio level. Clips also have crossfade etc crossfade at the beginning and end, which can be dragged to adjust the duration of the transition.
Adding a brief fade in and fade out makes the sound much smoother and less annoying to the ear when a new clip begins.
disconnect sound
Separate audio in iMovie to work independently with audio and video clips.
By default, iMovie keeps the audio and video portions of clips together, making it easy to work with and move around in a project. However, there are times when you want to use the audio and video portions of a clip separately.
To do this, select your clip in the timeline, then go to modifier drop down menu and select disconnect sound. You now have two clips, one with just the images and the other with just the sound.
There are many things you can do with the detached sound. For example, you can extend the audio clip to start before the video appears, or continue for a few seconds after the video has disappeared. You can also cut out parts in the middle of the audio while keeping the video intact.
Add sound to your projects
Add audio to your iMovie projects by importing music and sound effects, or by recording your own voiceover.
In addition to the audio that is part of your video clips, you can easily add music, sound effects, or voice-overs to your iMovie projects.
All of these files can be imported using the standard iMovie import button. You can also access audio files from the button content library (in the lower-right corner of the screen), iTunes, and GarageBand.
note : Accessing a song through iTunes and adding it to your iMovie project doesn’t necessarily mean you have permission to use the song. It could be copyright infringement if you show your video publicly.
To record a voiceover for your video in iMovie, go to window drop down menu and select Record voiceover. The voice-over tool allows you to watch the video as it’s being recorded, using either the built-in microphone or a microphone that connects to the computer via USB.
