How To Remove Background Noise In Adobe Premiere

Reading Time: 2 minutes

If you’re using real people in your videos then generally you only get one take, so it’s pretty frustrating when you get back to your PC to watch the clip and find that the audio is being obscured by background noise.

You’re then usually left with two choices. Don’t use the clip or make do and just put it out there, none of which are what you really want. But there is an easy solution. 

I use Adobe Premier CC for video editing and this video handily explains the simple steps to removing background noise and clearing up the audio

DeNoiser and Lowpass settings

There are hundreds of setting to tinker with so it’s nice to know that you just need two of the inbuilt effects to clean your audio.

  1. Go to Effects > Audio Effects > DeNoiser and drag the effect to your audio. Go to the Effect Control panel  and click edit on the DeNoiser settings. Set the first dial (Reducer) to -17 and the other dial (Offset) to 10.
  2. Go to Effects > Audio Effects > Lowpasss and drag the effect to your audio. Go to Effect Control and scroll down to the Lowpass setting and change the cutoff setting to 200Hz. In honesty I found I didn’t need this but included it here as it’s in the video.

Results

These setting worked great for me, but as with anything you may need to tinker with the values slightly but even without doing that you’ll notice an immediate improvement.

A Quick Note

The DeNoiser effect requires a couple of seconds to find the correct level so if you’re dealing with lots of noisy clips then you will still get some hum at the beginning of each clip. Annoying. If they’re the only thing on the timeline then you can add the Denoiser effect from the audio mixer panel rather that applying it to each clip. This will get rid of the delays at the beginning of each clip.

Open the audio mixer panel and you should see a slider there for each track and a master. At the top left of the mixer panel UI is a triangle toggle like the ones on all of the bins in Premiere’s UI. Use the toggle to expand the mixer panel to show the fx bus. There you can pull down a list of all of the audio fx to apply to each track. After adding an effect to a track, right click on it and choose “edit” to make adjustments. You can do this while your timeline is playing to hear the results. You can also keyframe effects on the timeline by setting the track display to “show track keyframes”. That option is down on the audio tracks in the timeline panel. – Adobe Forums
