The timeline in your movie project is where you arrange all of your audio clips, such as background music and special effects. Audio clips always appear beneath video clips in the timeline.

Move an audio clip

You can move an entire audio clip, except the background music, to a different place in your project.

  1. In the iMovie app on your iPhone, open a movie project.
  2. Touch and hold a blue or purple audio clip in the timeline until it pops off the timeline.
  3. Drag the clip to a new location in the timeline, and release.

  3. Drag the trim handles at either end of the clip to the points where you want the audio to begin and end.If a trim handle won’t move right or left, it means there is no additional audio to work with on that end of the clip.An audio clip being trimmed in the project timeline.
  4. Tap outside the audio clip to make the trim handles disappear.

Split an audio clip

There are two ways to split an audio clip in a movie project. When you split a clip, you can remove unwanted sections, or adjust the duration, volume, or speed of each section.

  1. In the iMovie app on your iPhone, open a movie project.
  2. Scroll the timeline to position the playhead where you want to split an audio clip.

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

Remove an audio clip from a project

When you remove an audio clip that you added from the media browser or recorded with your device, it’s removed from the movie project but is still available in the media browser (in Audio > Recordings) so that you can use it in another project.

  1. In the iMovie app on your iPhone, open a movie project.
  2. Do one of the following:
    • Touch and hold the audio clip in the timeline until it pops off the timeline, then drag it above the timeline; when you see the puff of smoke in the corner of the clip, release it.An audio clip being deleted in the project timeline.
    • Tap the audio clip in the timeline to reveal the inspector at the bottom of the screen, then tap Delete (if Delete doesn’t appear, tap the Actions button ).

Move audio to the background or foreground

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. You can choose which audio clips are in the background or foreground (you can have three foreground audio clips and one background audio clip playing at a time).

  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 Actions button , then tap Background or Foreground.

The color of the clip changes to indicate whether it’s background music (green) or foreground audio (blue or purple).

  • Use the best quality microphone you can afford.
  • Use default Camtasia Recorder audio settings.

While professional studios use specialized equipment such as studio microphones and mixing boards to create sounds of higher quality, basic editing can be done quite easily with just a virtual studio installed on a home computer. The basic features of the sound editing software remain the same.

    1. Image titled Edit Audio Step 1 1 Install a software that can edit sound on your computer.

There are many programs available but here are some of the popular ones that you may want to choose from.
      • Audacity: an open source software that can record and edit multiple tracks. It also has a very effective noise removal function to remove hissing, static and humming by simply selecting a sample of the noise and then removing it from the whole track.
      • Power Sound Editor: can record and change tracks that need to be mixed with other parts of a musical composition. You can also alter the audio data by adding time-shifting effects such as Echo, Chorus and Reverb. Power Sound Editor allows you to easily share your edited audios over the Internet or through email. You can also burn finalized files onto a CD.
      • Mp3DirectCut: specializes in recording and editing MP3 files. This file format is ideal for someone who wants to compress files to smaller sizes.
      • Wavosaur: specializes in capturing and processing WAV files. It offers real-time effects so you can hear what the effects sound like while you are recording the audio. Wavosaur also supports MP3 format.

    • Record on multi-tracks if you have a computer with more than 1 microphone port.
    • Dub over other tracks by recording a new track while the tracks that have already been recorded play in the background.
    1. Image titled Edit Audio Step 3 1 Import and export audio files easily by connecting your computer to external devices via USB. Most sound editing programs allow you to import and export in various formats, including AIFF, OGG VORBIS, WAV and most popularly MP3.


  1. Image titled Edit Audio Step 4 1 Edit recorded or transferred audio files using an audio editing software. Every software has its own unique set of features to edit audio but here are the most common ones.
    • Copy and paste parts of a track to rearrange the composition.
    • Delete unwanted tracks or parts of a track.
    • Mix tracks together by adjusting volume levels of tracks individually.
    1. Image titled Edit Audio Step 5 1 Add digital effects to your audio tracks to enhance the sound of the instruments or vocals. Most virtual studio software offers the following effects.
      • Pitch change: to give the track a higher or lower pitch.
      • Noise reduction or removal: this reduces or removes hissing and other unwanted background noise.
      • Echo, Flanger, Delay and other similar effects that repeat or shift the time of notes to make them sound fuller.
