So, for this specific example, I set the reduction percentage to 65 and kept the decibel level at 15. Reduce By is the same but using decibels.

Now you’ll have two different tools to play with: “Noise Reduction” and “Reduce By.” Noise Reduction will let you play with how much you want to reduce the noise, in terms of percentages. Now go back up to Effects > Noise Reduction/Restoration > Noise Reduction (process). Once you’ve hit “Capture Noise Print,” click anywhere on the timeline. This will extract a noise profile, then Audition takes this information and tries to remove it from the rest of the clip. Now, go to Effects > Noise Reduction/Restoration > Capture Noise Print. This is because we want to edit out the humming or noisy background audio only. Once you’ve done this, take the Time Selection Tool and find a piece of the clip that has no dialogue. First, you’ll need to take the audio clip and move it over into Audition.
