Background noise is by no means permanent. With easy-to-use noise removal tools like Riverside’s, cleaning your audio is easier than ever. This article walks you through how to prevent background noise in the first place and how to remove it from your audio or video if you need to. 

TL;DR

  • Background noise comes in many forms. It can be a buzz, murmur, hiss or high-pitched sound.
  • Minimizing the risk of background noise before and during your recording is essential. 
  • Make sure to record in a quiet environment, using the right tools, and taking as many precautions as possible. 
  • Riverside has a background noise removal tool that works during your recording. You can also remove background noise in the built-in editor. 

What is background noise in videos? 

Let’s start by defining what ‘background noise’ is in videos. Background noise refers to any unwanted ambient sounds in your video recording's audio. For example, this could be a buzzing, a hum, or a high-pitched sound. 

Different types of background noise

Believe it or not, background noise actually falls into different categories: 

  • Broadband noise/wideband noise is background noise that occurs across a wide range of frequencies 
  • Narrowband noise is the opposite of broadband noise, occurring over a limited range of frequencies. 
  • Impulse noise covers noises that sound like pops and crackles. Pops occur from plosive sounds such as ‘p’s in speech, whilst crackles usually come down to electrical equipment. 
  • Irregular noise is background noise that is location specific. This could be weather-related or something like your fan or AC unit. 

Can you remove background noise from a video?

Don’t worry, though. It’s possible and easy to remove background noise from your videos, as long as you use the right tools. Some platforms offer AI-powered background noise remover features, while others allow you to do it manually. 

How to Remove Background Noise from Videos & Audio Recordings: The Basics

Minimize background noise during recording

The very first step to removing background noise from your recordings is to implement best practices during recording. This means: 

  • Optimizing your mic placement
  • Using a noise-cancelling mic 
  • Trying to record, wherever possible, in quiet environments.
  • Identifying potential sources of background noise (like your noisy AC) and turning these off!
  • Using the right type of mic and investing in a mic stand and pop filter
  • Adjusting your gain levels to ensure you’re not going overboard and distorting your audio 

Depending on your recording software, you may also have access to a background noise remover that works actively as you’re recording. This should work to minimize your workload during post-production. 

Identifying background noise

The first step to eliminating background noise from your recording is to identify it. When you’re listening back to your recording, note down any noises that you want to get rid of. These could be present throughout the recording or occur at certain moments. 

Basic Noise Removal Techniques

Noise Gates 

Noise gates work by setting certain frequency limits or thresholds. These ‘gates’ block any sounds that fall below your set frequency minimum. This works to mute any irrelevant background noise automatically. You can toggle the amount that your noise gate affects the volume of any audio below the threshold. This is called the noise gate ‘ratio’. 

Reverb & echo removal 

Reverb removal is all about eliminating what are known as ‘audio tails’ and echoes. These commonly happen in audio tracks when you’ve recorded in a large and open space. These audio tails and echoes can muddy the quality of your audio, so reverb removal tools help you to neutralize their impact. 

EQ

The EQ or Equalizer gives you the ability to control the volumes of different frequencies. This means you can very easily minimize the volume of your background noise by identifying the frequency it sits at. 

How to remove background noise from audio and video with automated tools

Removing background noise doesn’t require expert knowledge or know-how. In fact, a lot of platforms nowadays make your life super easy with automated background noise removal tools. Let’s take a look at some of the best ones out there:
