How to Screen Record without Background Noise

As a recording expert, the most typical task video producers ask for is to eliminate irritating noises from completed video pieces, such as rumbles or buzzes. It’s tough to get good audio when filming since the dialogue is sometimes muffled by ambient noise, such as the dreaded whir of an air conditioner or fans.

When working with sound effects or other video design components, it is usual practice to reduce or eliminate the ambient noise because it can be super-annoying to have weird noises in your background when you listen to the recorded version.

Although there are ways to eliminate this background noise, a few options are available. Adding background music to your film or using audio or video editing tools might help lessen the noise. How to reduce background noise on Windows, Mac, and Online? Read the article in detail to get started!

6 Ways to Reduce Background Noise Manually

The following are the five ways that will help you eliminate/reduce background noise manually:

Shorten the distance between the subject and the microphone

To improve the quality of your recordings, it is recommended to decrease the distance between the microphone and the subject while increasing the distance between the microphone and surrounding noise. By minimizing the subject-to-microphone distance, the speech can be captured more clearly and accurately. At the same time, increasing the microphone to noise distance can help reduce unwanted background noise and improve the overall sound quality.

Create a quiet environment

Before recording, try to remove any sources of acoustic noise if you can. The sound may be easily removed in post-production if, for example, an air conditioner is nearby.

Similarly, if the sound of passing traffic bothers you, finding a new abode is the best course of action. This is easier said than done, for the most part. In addition, wind noise must be minimized.

Mic preamplifiers may be damaged by wind noise, resulting in artifacts that are very hard to eliminate. If you’re recording outside, protect your microphones with windscreens. Wind noise, for example, may easily be detected with a fast listen via headphones.

Use directional microphones

Off-axis audio signals, or signals beyond the microphone’s optimal pickup region, are less responsive to cardioid, super cardioid, and shotgun polar pattern microphones.

This characteristic may be used to mute the sounds in the environment. Mics should be positioned such that the noise sources are located in the microphone’s polar pattern’s “null,” or the polar pattern’s area with the least sensitivity.

To determine the precise null angle, the polar pattern must be considered. A cardioid microphone’s null angle is 180 degrees off-axis. The null angle changes to a different location as microphones get more directional. A super-cardioid microphone has a null point between 127 and 233 degrees on the horizontal axis.

Use low-cut filters on the first stage of microphones or amplification

Low-frequency noise is the most common background noise; the higher frequencies are less common. When recording dialog, it’s best to use a high-pass (also known as a low-cut) filter since there’s so little energy in the voice below 100 Hz.

A significantly more aggressive high-pass of up to 320 Hz may be utilized when speech intelligibility is more critical than retaining a natural, full-sounding voice output.

It is important to remember that “telephone-grade audio,” which is tuned for 90% of speech energy, has a frequency response of around 300–3,000 Hz.

The high-pass filters of many microphones are built-in. First, place the microphone filter on it. Activate the preamplifier’s high-pass if an extra high-pass is required.

Both microphone and preamplifier utilize high-pass filters, resulting in a steeper filter slope that reduces low frequencies more quickly.

Reduce the number of open microphones

The term “open” describes microphones that are actively recording. The total background volume in the mix rises by 3 dB as the number of open microphones doubles.

To put it another way: When recording an eight-person conversation with eight microphones open, there is a 9 dB speech-to-noise penalty. For unscripted content, managing a scenario with several talkers is tough to execute manually.

Sound Devices / For sound pros, MixAssist and Dugan automated mixing allows them to concentrate on the overall mix rather than manually opening and closing microphones.

Use real-time noise suppression

Few portable choices have been available for real-time noise suppression in the field, even though there are numerous possibilities for noise reduction through computer CEDAR’s portable real-time noise reduction equipment for sound professionals has been a popular option on site.

First time in production sound history, NoiseAssist from Sound Devices provides adaptive, real-time noise reduction in a mixer recorder. NoiseAssist employs an innovative algorithm to extract speech from background noise in the real-time, single-ended noise reduction algorithm.
