Do you need to remove background noise from audio for your upcoming podcast or video production projects? Do it effortlessly with these online/offline audio editing tools.

Ambient noise in recorded audio or video is unavoidable. You can not record every video or audio from a silent room. If you do, you will still discover a humming noise from your laptop, desktop, fan, air conditioning, etc.

Instead of investing too much money and time in eliminating background noise, you can just eliminate the noise from the recorded audio

There has been much development in noise reduction algorithms. You can take advantage of such algorithms by using any of the apps mentioned in this article. 

Also, read on to discover more about audio noise so that you can create plans to produce crystal-clear audio for your content.        

Noise in Audio


The residual low-level sounds in an audio recording are noise. These are distinctive sound waves other than your voice, musical instruments, or audio from gameplay. The default sound of your recording environment, those you can hear during a quiet section of your audio, is also noise. 

Noise can be static sound created by electrical interference of wires that plug your speakers and microphones into the computer or other recording devices.

For sure, you will capture some level of noise during podcast recording, YouTube video recording, etc. But, when that noise distracts the audience or forces them to stop playing and look for other content, that is a problem.

For example, consider you are recording a YouTube video in front of a teleprompter. To feed content to the teleprompter, someone is constantly typing. Your microphone can record the crackle of the keyboard if you do not use a separate recording room. Now, if you allow this in the final video, the audience will surely feel distracted.     

How Does Noise Affect Recording and the Final Audio/Video?


The primary negative impact of noise on audio or video content is diverting the focus of the audience. Audio and slideshow-based videos must be free from noise. 

Because, in such content, the audience needs to focus on your commentary to understand the subject you are discussing. The visuals, if any, are not sufficient to understand the whole topic.

Other major effects are: 

  • Audio noise creates a question in the audience’s mind about the professionalism of your YouTube or podcast channel.
  • If you are discussing audio products or concepts for content creation and the listeners hear noise, that is not good for your channel’s reputation.
  • Some background noise can create major health issues like nausea, headache, hypertension, mental stress, etc.
  • When you are teaching musical instruments through recorded audio or video, background noise can impact the learning capability of your content subscribers.

The negative effects of noise on recorded content are plenty. Some are obvious while some are not. But noise surely reduces your content views, likes, and subscriptions.        

How to Reduce Ambient Noise Before Recording

Though advanced tools help you eliminate most of the background noise, it is good to reduce ambient sound during recording to get the best result. Here are some suggestions you must follow before recording: 

Use a Cardioid Microphone

Use a Cardioid Microphone

Post-processing of recorded audio to reduce noise is a time-taking process. Hence, you must use a microphone that reduces the noise during recording by not capturing the ambient audio. Cardioid microphones are good examples.

These microphones are highly sensitive to sound to which you point the front of the mic. Additionally, these mics virtually reject all the sounds in its rear because of low input dB at the back.     

Record the Voice in a Quiet Place

If your video allows you to record the voice later, do it from a quiet place. For podcasts, you can always do that from a quiet room since no one will see you.

You may use heavy rugs, curtains, and wooden furniture to reduce room echo.    

Record the Ambient Noise

Before giving your voiceover, record the ambient sound (room tone) of your room for 20 to 30 seconds. You can upload this file as an example for the post-processing software to remove background noise.

Use Minimum Gain

Set the microphone in the lowest possible gain or input dB. You will need to test the microphone multiple times in different dB inputs to find out the lowest scale you can use. 

Reduce Mouth and Mic Distance

Reduce Mouth and Mic Distance

The mouth-to-mic distance should be six inches or less. This will enable a low gain to record a crystal clear sound of your voiceover. 

Place the Microphone Away From the Ambient Sound

While using a unidirectional or cardioid mic, place its front away from the noise. The mic will nullify much of the noise.  

Shut Down Some Room Appliances 

Switch off appliances like air conditioning, heater, cooler, dehumidifier, fan, exhaust, etc. 

How to Remove Noise After Recording

Once you have recorded your voiceover by following the above tips, the post-processing of the audio becomes super-easy.


Post-processing is the editing workflow where you remove background noise from audio, remove fumbling from your recording, reduce fillers, etc. 

Many online and offline audio editing apps help you reduce or eliminate noise from an audio recording. Currently, most of these apps use artificial intelligence (AI) and neural networks to spot and delete noise from voiceover.

The standard workflow is as follows: 

  • You download and install the app or use its web app version.
  • Upload a noise profile, the room tone that you recorded earlier.
  • Set manual or automatic noise reduction settings. Automatic settings deliver fair results.
  • Start the noise removal process. 

Such apps usually remove constant background noise like whistles, hums, buzzes, hiss, whines, fan noise, etc. Irregular noise, like pops, clicks, traffic noise, etc., will require manual editing.
