How to Remove Background Noise From Videos

Background noise in videos may annoy viewers, distracting them from the content. It can also prevent the creators from getting their message across. Your AC unit, fan, phone calls or messages, keyboard taps, and mouse clicks can ruin your audio quality. The same goes for wind, traffic noise, and other sounds in outdoor settings.

Fortunately, you can remove background noise from a video with a few clicks. It will help you create clean, crisp, studio-quality audio. Learn when and how to do it.

• Professional interviews: Crystal clear audio in interviews is crucial for credibility and professionalism. Anything less irritates viewers. It also prevents your interviewees from hearing you loud and clear.
• Conferences or seminars: High-quality audio without background noise helps convey intended messages and engage participants. It also eliminates misunderstandings and makes events more productive.

Part 3: Tips and Tricks to Clean Noise When Shooting Videos

AI-powered solutions like Wondershare DemoCreator let you remove ambient noise from videos in post-production with a few clicks. However, you can clean the noise from videos while recording to save time. Here are the essential steps to do the trick.

Tip 1: Find a Quality Acoustic Environment

A controlled acoustic environment while recording is crucial for better sound quality. It lets you record natural, accurate sounds.

When recording in a room, use proper acoustic treatment to reduce unwanted reverberations and echoes. Carpets, curtains, and soft furnishings are excellent because they absorb sound. You can also dampen noise with acoustic foam barriers, soundproofing panels, and similar materials.

Don't forget to remove fans and other unnecessary acoustic noise sources. Turn off your AC unit and close the windows to block traffic noise and other sounds from the environment. Create a noise-free space for clean, consistent audio.

Are you recording outdoors? Reduce noise with a noise gate, equalization, frequency cutoffs, and acoustic foam barriers.

Tip 2: Use an External Directional Microphone

It focuses on one direction, reducing ambient noise and helping you get clean audio.

Many noise-canceling microphones have multiple polar patterns and filter settings for various environments. Whichever microphone you choose, get a sturdy mic stand and a pop filter to eliminate popping sounds, primarily plosives.

Tip 3: Put the Microphone Close to the Subject

Your mic placement is another factor that can make or break your audio. Therefore, place the microphone close to the subject (near the speaker's mouth).

It will help you achieve a high speech-to-noise or signal-to-noise ratio (SNR). The higher the SNR, the better the sound quality. Anything greater than 0 dB means that the speech is louder than the noise. An SNR of 30 dB or higher indicates clean speech, although it's intelligible even at 0 dB.

Conclusion

Video background noise reduction is vital for achieving clean audio and attracting more viewers. You can reduce ambient noise while shooting videos with a directional microphone, proper mic placement, and acoustic treatment. You can also remove it when editing with advanced software like Wondershare DemoCreator.
