How to Get Background Noise Out of a Video: When Silence Speaks Louder Than Words

In the world of video production, background noise can be the bane of any creator’s existence. Whether you’re filming a vlog, a documentary, or a corporate presentation, unwanted sounds can distract your audience and diminish the overall quality of your content. But fear not! There are numerous ways to tackle this issue, ranging from simple fixes to more advanced techniques. In this article, we’ll explore various methods to remove or reduce background noise from your videos, ensuring that your message comes through loud and clear.

1. Prevention is Better Than Cure: Minimizing Noise During Recording

The first and most effective way to deal with background noise is to prevent it from being recorded in the first place. Here are some tips to help you achieve a cleaner audio track during the filming process:

  • Choose the Right Location: Select a quiet environment for your shoot. Avoid places with high levels of ambient noise, such as busy streets, construction sites, or crowded cafes.

  • Use a Directional Microphone: A directional microphone, such as a shotgun mic, is designed to pick up sound from a specific direction while minimizing noise from the sides and rear. This can significantly reduce unwanted background sounds.

  • Wind Protection: If you’re filming outdoors, use a windscreen or a furry windjammer to protect your microphone from wind noise. Even a light breeze can create distracting sounds on your audio track.

  • Monitor Audio Levels: Always wear headphones while recording to monitor the audio in real-time. This allows you to catch any unwanted noise and make adjustments on the spot.

2. Post-Production Magic: Removing Noise with Software

If you’ve already recorded your video and are dealing with background noise, don’t despair. There are several software tools and techniques you can use to clean up your audio in post-production:

  • Noise Reduction Plugins: Many video editing software programs, such as Adobe Premiere Pro, Final Cut Pro, and DaVinci Resolve, come with built-in noise reduction plugins. These tools analyze the audio track and remove or reduce background noise while preserving the clarity of the main audio.

  • Third-Party Audio Editing Software: For more advanced noise reduction, consider using dedicated audio editing software like Audacity, Adobe Audition, or iZotope RX. These programs offer more sophisticated noise reduction algorithms and greater control over the process.

  • Spectral Editing: Some audio editing software, such as Adobe Audition, allows you to visually identify and remove noise using spectral editing. This technique involves viewing the audio waveform in a spectral display, where you can pinpoint and eliminate specific frequencies associated with background noise.

  • Manual Noise Reduction: If you’re comfortable with audio editing, you can manually reduce noise by isolating the unwanted sounds and applying filters or EQ adjustments. This method requires a good ear and some patience, but it can yield excellent results.

3. AI-Powered Solutions: The Future of Noise Reduction

Artificial intelligence is revolutionizing the way we approach audio editing. AI-powered noise reduction tools can automatically detect and remove background noise with impressive accuracy. Here are a few examples:

  • Descript: Descript is an AI-powered audio and video editing tool that offers a feature called “Studio Sound.” This feature uses machine learning to remove background noise, echo, and other unwanted sounds, leaving you with clean, professional-quality audio.

  • Krisp: Krisp is an AI-powered noise cancellation app that works in real-time during video calls and recordings. It can remove background noise from both your microphone input and the audio coming from other participants, making it a great tool for remote interviews or virtual meetings.

  • Adobe Podcast Enhance: Adobe’s Podcast Enhance tool uses AI to automatically clean up audio recordings. It can reduce background noise, enhance speech clarity, and even balance audio levels, making it a valuable tool for podcasters and video creators alike.

4. Creative Solutions: When Noise Becomes Part of the Story

Sometimes, background noise can add character and context to your video. Instead of removing it entirely, consider using it creatively to enhance your storytelling:

  • Ambient Soundscapes: If you’re filming in a specific location, the ambient noise can help establish the setting and mood. For example, the sound of waves crashing on a beach or birds chirping in a forest can add depth and realism to your video.

  • Diegetic Sound: In narrative filmmaking, diegetic sound refers to audio that originates from within the story world, such as dialogue, footsteps, or environmental sounds. By carefully incorporating background noise into your sound design, you can create a more immersive experience for your audience.

  • Sound Layering: If you’re working with multiple audio tracks, consider layering them to create a rich, textured soundscape. For example, you could mix in subtle background noise to complement the main audio, adding depth and dimension to your video.

5. DIY Techniques: Home Remedies for Noise Reduction

If you’re on a budget or prefer a hands-on approach, there are several DIY techniques you can try to reduce background noise:

  • Soundproofing Your Space: You can create a makeshift soundproofing setup by hanging heavy blankets or curtains around your filming area. This can help absorb sound and reduce echo, resulting in cleaner audio.

  • Using a Pop Filter: A pop filter is a screen placed in front of a microphone to reduce plosive sounds (like “p” and “b” sounds) and other noise. While it’s primarily used for vocal recordings, it can also help minimize background noise.

  • Recording in a Closet: Believe it or not, recording in a closet can provide excellent sound isolation. The clothes and soft surfaces absorb sound, creating a quiet environment for your recordings.

6. Professional Help: When to Call in the Experts

If you’ve tried all the above methods and are still struggling with background noise, it might be time to seek professional help. Audio engineers and sound designers have the expertise and equipment to tackle even the most challenging noise issues. Here are a few scenarios where professional assistance might be necessary:

  • Complex Audio Tracks: If your video contains multiple audio sources, such as dialogue, music, and sound effects, a professional can help balance and clean up the audio for optimal clarity.

  • High-Stakes Projects: For important projects like corporate videos, commercials, or feature films, it’s worth investing in professional audio post-production to ensure the highest quality.

  • Time Constraints: If you’re on a tight deadline, hiring a professional can save you time and ensure that your video is ready for release without compromising on audio quality.

7. The Importance of Testing and Iteration

No matter which method you choose, it’s crucial to test and iterate on your audio. What works for one video might not work for another, so be prepared to experiment with different techniques and settings. Here are some tips for effective testing:

  • A/B Testing: Compare different versions of your audio to see which one sounds best. This can help you identify the most effective noise reduction method for your specific situation.

  • Feedback from Others: Don’t hesitate to ask for feedback from colleagues, friends, or your target audience. They might notice issues that you overlooked and provide valuable insights.

  • Continuous Learning: The world of audio editing is constantly evolving, with new tools and techniques emerging all the time. Stay curious and keep learning to stay ahead of the curve.

8. Conclusion: The Art of Silence

Removing background noise from a video is both a science and an art. It requires a combination of technical skills, creative thinking, and a willingness to experiment. By following the tips and techniques outlined in this article, you can significantly improve the audio quality of your videos and create a more engaging experience for your audience. Remember, sometimes the most powerful moments in a video are the ones where silence speaks louder than words.


Q: Can I remove background noise from a video without using any software?

A: Yes, you can reduce background noise by using physical methods such as soundproofing your recording space, using a directional microphone, or recording in a quiet environment. However, for more advanced noise reduction, software tools are usually necessary.

Q: What is the best free software for removing background noise from a video?

A: Audacity is a popular free audio editing software that offers noise reduction features. It’s a great option for beginners and those on a budget.
