How to Remove Background Noise in Audacity in 2024

Recording audio and video that is crystal clear in terms of voice is every person's dream. However, a few factors stop you from getting that crystal-clear audio and ruin the quality of your overall audio and video. Maybe you have recorded a song in your room, and the voice of your ceiling fan or computer fan is acting like a lousy instrumental, or perhaps you recorded something outside.

Some software come to our rescue in such situations, saving us from the hassle of re-recording and allowing us to remove background noise easily. One such software is Audacity which is famous for its noise reduction that has removed background noises from millions of videos.

We will be discussing how to get rid of background noise in Audacity, the reason why Audacity remove noise feature is not working for you and the best software alternative to Audacity background noise which is packed with many features along with noise reduction.

A Step-by-Step Guide to Remove Background Noise in Audacity

Create Noise Profile

Now, this part sounds crazy and the reason why people think twice before considering noise reduction Audacity, but we will make it simple for you.

To do this, you create a noise profile from your audio which is a section from your audio that only has the background noise. A noise profile section should be at least 0.05 seconds long; if it's shorter than this, then Audacity will throw an error, and once you close Audacity, the Noise Profile gets deleted, and you have to create another.

We need it because of noise gate Audacity, which is used for filtering the background noise out of any audio, so if the audio is above a certain threshold, it will let it pass. If the audio is below that threshold, then the Audacity noise gate will remove it from the audio.

Now that we have learnt the complete noise removal Audacity formula, let's jump towards the step-by-step guide.

  • Download and launch the Audacity software.
  • Click on File, then click on Import and then click on Audio to load your audio file.
  • Select your Noise Profile by clicking and dragging a certain section out of your audio that meets the criteria of Noise Profile mentioned above using the Selection Tool.
  • Click on Effect and then click on Noise reduction.
