Video Edit Magic's volume tracks provide you with a very flexible method to change volume of any portion of audio in the timeline.

When you add your video to the timeline, the audio portion of the video appears on the Audio 1 track. You can use Audio 1 track's volume track to mute portions of audio. To do so, drag a volume point to 0% where you want to mute the audio.

Please refer to Video Edit Magic's help document to learn more about volume tracks.

After you have muted portions of audio (portions that contains abusive words), use a separate audio file, with a `beep' sound. Place the audio file in the Audio 2 track right below the portion that you had muted in the Audio 1 track.
