Before we start how to remove noise in Audition, make sure you prepare the following things:

  • Make sure the specs of computer either desktop PC or Laptop can run Adobe Audition software.
  • To follow this tutorial, you need Adobe Audition software ready in your computer. This tutorial uses Adobe Audition CC 2018 by the way. But the steps might be the same in other versions of Adobe Audition.

Voice Recording Tips

You can record a voice or vocal audio using a simple device such as a smartphone or a small portable microphone like Bluetooth mic for mobile devices. You can record it anywhere, like in your room, park, office, or school (when your teacher teaches a lesson). But when it comes to recording your voice, furthermore in making a podcast or to voice-over your video, no need to rush to speak between dialogues you are going to speaking up. In other words, make a bit longer pause between conversations in your audio recordings. That will make it easier for you to remove noise in Audition software.

After you finish the voice recording process, store the audio file to your computer where the Adobe Audition installed and ready to use.

How to Remove Noise in Audition

Step 1. Open Your Audio File

Open your Adobe Audition. Then, at the top menu, click File → Open, or you can use a Ctrl + O on your keyboard. And there you can browse to look for the audio file you are going to denoise. Or open the folder in your computer, drag and drop your audio file into the Audition user interface.

From the sound wave shown above, you can see a few seconds of silence in the audio recording file. It’s about 3 seconds before the dialogue starts. I recorded my voice using an Android smartphone. So, before I began to speak, I let my audio recorder app records a few seconds of silence. What for? We are not just recording a real silence, but also recording some noises from the environment. It’s necessary because we can use such noises to become a sample for removing noise in Audition. So. take a few seconds of silence in audio recording only before the dialogue or voice begins.

Step 2. Noise Sampling

Select an area from the sound wave of your audio file by blocking it for noise sampling. I chose the first 3 seconds of the sound wave.

After blocking a particular part of the sound wave for noise sampling, go to Effects → Noise reduction/restoration → Capture noise print on the top menu. This way will take a sample noise from the area of the sound wave you just blocked.

Step 3. Noise Reduction Processing

Let’s continue the work on the editor window, block which parts of your sound wave you want to reduce the noise. Or you might want to block the entire sound wave by using Ctrl + A shortcut on your keyboard.

Then, go to Effects → Noise reduction/restoration → Noise reduction (process). A noise reduction pop up window will appear. If you have no idea what to adjust on that window, click Apply.

That way will denoise your audio file based on the noise sample. Try playing your audio recording again to hear the result, and you will listen to the noise has gone.

In case the main vocal becomes vague after the noise reduction process, you can press Ctrl + Z (undo) on your keyboard and repeat from step 2. That’s how to remove noise in Audition. But if you are still not satisfied with the result, got to the next step.

Step 4. Improving the Audio Quality

This step is optional, but you can perform this step if you want to improve your audio recording quality. In the “effects rack” section, click the triangle button as shown at the image below. Then, go to Filter and EQ → Parametric Equalizer.

Now, at this parametric equalizer window, you can adjust the equalizer to improve your audio recording. If you have no idea to do manual settings on it, you can apply the presets for your audio recording file. You can find some presets in the drop-down menu. But if your recording type is vocal audio, you can apply the “Vocal Enhancer” preset.
