The clips in this sequence have already been assigned the Dialogue audio type in the
Essential Sound panel, and the Auto-Match option in the Loudness category has been
applied.
Select the first clip in the sequence. In the Repair section of the Essential Sound panel,
select the box to enable the Reduce Noise option. The default setting for the effect intensity
is 5.
Play the clip in the sequence to hear the difference. The loud rumble that begins at about
00:00:10:00 is immediately much quieter.
As with many effects, trial and error will usually yield the best results. Try adjusting the
effect intensity—if the effect is too strong, speech might begin to sound like it’s underwater
or distorted. If the effect is not strong enough, too much of the unwanted background sound
might remain. When you have finished experimenting, leave the setting on 5.
Tip
You can reset any setting in the Essential Sound panel by double-clicking the control.
Part of the challenge in working with this audio is that some of the low-frequency
background sound is close to speech, making it harder to automatically remove. Let’s use
the more advanced settings.As soon as you enable the Reduce Noise option in the Essential Sound panel, a DeNoise
effect is applied to the selected clip, visible in the Effect Controls panel. If you can’t see the
Effect Controls panel now, you can access it via the Window menu.- Open the Effect Controls panel and make sure the first clip is still selected in the Timeline
