Tutorial: Removing Pops and Clicks and Background Noise in Adobe Audition CS6
Two types of noises degrade the audio you shoot with your video: random noises like microphone clicks and pops, and consistent noises like white noise or air conditioning hum. This tutorial demonstrates how to remove both of them in Adobe Audition CS6.
There are two types of noises that degrade the audio that you shoot with your video: random noises like microphone clicks and pops, and consistent noises like white noise or air conditioning hum. In this tutorial, I'll show you how to remove both of them in Adobe Audition.
Sending the Audio Clip to Audition
Figure 1 (below) shows a waveform of the audio clip we're going to be working with, and in the Source Window you can see that there are some pretty significant pops and clicks (represented by the long, thin vertical lines that pop out in the waveform). We also see that the audio is too low. (Be sure to refer to the video at the top of this page to hear the noises I refer to in the text of this article.)
Figure 1. The waveform we'll be working with-multiple pops and clicks, and overall volume too low.
Any time you boost audio volume, you run the risk of background noises appearing and getting significant. If you're working with Adobe Production Premium CS6, you'll want to perform this work in Adobe Audition, the professional audio editing application that ships with Premiere Pro CS6 when you purchase it in most Creative Suite versions.
To open the clip in Audition, select the file in the timeline, then choose Edit > Edit in Adobe Audition > Clip (Figure 2, below) to choose the clip, not the sequence, and open it in Audition.

Adobe Production Premium then does a Render and Replace, where the original audio gets replaced with the Audio Extracted_2.wav file shown in Figure 3 (below), and Figure 4 (below Figure 3) shows the audio file in Audition. And we do in fact see several significant pops and clicks in the waveform now opened in Audition, as shown in Figure 4.
