How to Remove Background Noise From Audio: 5 Simple Steps

Every once in a while, we all wish we could remove background noise from audio. It's not always possible to record your audio in a quiet room. Sometimes you just have to record yourself when you're driving, sitting in a park, or somewhere near a construction site. But does that mean that your audio is doomed to be noisy and disturbing?

Absolutely no. We'll tell you how to remove background noise from audio within a few clicks. In fact, with Podcastle, you just need to follow 5 simple steps to remove background noise from audio. But before we get there, let's skim through some definitions.

But first, let's define:

What is background noise?

Before we understand how to do background noise removal online and get a crystal-clear recording, let's understand what background noise is.

In the audio industry, when we say noise, we refer to the low-level sounds of the audio recording, like ambient sound. Most of the time, this "noise" is the natural component of the audio track, and no one even notices it. But when it consists of troubling and unwanted background sounds, it can disturb the listeners and ruin your audio track.

Here are the three main categories of audio noise that we define here at Podcastle:

The tone of the room

Every room has its sound. Even when no one is talking and nothing is really happening, there is a certain audio quality specific to each recording environment that you can hear. That sound is called the "room tone."

The indirect sound  

When speaking, you're producing two kinds of sounds: direct and indirect sounds. The direct sound is the sound that goes directly from you to the microphone. The indirect sound is the remaining sound that is left reverberating or bouncing in the recording environment.

That's why, when you're recording in the closet, the sound gets dampened by the carpets and other soft surfaces. Whereas, when you record, let's say, in the garage, your sound gets reflected because of the hard surfaces and causes echo.

The response from the mic

Why do you think it is recommended to use sound-blocking microphones? This is because all the mics pick up the sound differently. If your microphone is of really high quality, it will mirror your room's recording conditions and respond to different frequencies, staying as true as possible to the way your voice actually sounds in the room.

On the other hand, the low-quality mics will hear the sound differently, not picking up the range of frequencies and imprinting the mic noise (the sound generated by the mic itself). Depending on the mic, its generated noise can either sound "smooth" or "crackly."

Now that we precisely understand what is considered to be background noise, let's see how you can reduce that noise while recording:

How to reduce the background noise?

If you want to achieve a professional-quality podcast or any other high-quality audio track, you need to try your best to reduce the amount of disturbing noises when recording. To do so, you should try to find the best speech-to-noise ratio, or, in other words, find a place with subtle room tone, and get the perfect balance of clean direct speech and indirect background noises.

But don't worry, although it sounds complicated, it is pretty simple in reality. Here are just a couple of tips to follow to avoid the background noise as much as possible when recording:

-- Choose a dynamic mic.
-- Find the quietest recording space possible.
-- Try to point your mic away from the noise.
-- Record the room tone to use it during the post-production.

But of course, we understand that it's not always possible to follow these tips and get the best conditions during the recording stage. So how can you remove background noise after the recording? No need to watch long, how to remove background noise, tutorials— you can do it within a couple of minutes using our audio editing software.
