How to Remove Background Noise from Video (Desktop & Mobile)

"I created a video for uploading to YouTube but can't remove the background noise in the video. Is there a way for video noise reduction? What is the best app to remove or minimize the background noise in my recorded videos?"

Technically speaking, noise is defined based on the audio frequency and audio decibel, which is loud, disruptive, and out of the comfort area of human hearing. Hiss, rumble, crackle, hum, and even white noise are instances of noise in the audio. Also, all kinds of unwanted sounds in video recordings are noises.

To some extent, background noise would destroy your recorded video, no matter how carefully the shooting was conducted. But is there any app to remove background noise from video? This article will show you how to remove background noise from video on iPhone, Android, and desktop with some best background noise removal apps.

What is Background Noise

Background noise refers to any unwanted or incidental sound that is present in a given environment or audio signal, which can obscure or interfere with the desired primary signal or content. It typically arises from various sources, including environmental factors (e.g., traffic, wind, machinery), electrical interference (e.g., hums, static), or incidental sounds (e.g., conversations, footstep sounds).

In professional audio, telecommunications, or broadcasting contexts, background noise can significantly degrade the quality of the signal, reducing clarity and intelligibility. In such cases, it becomes crucial to employ techniques and technologies—such as noise reduction algorithms, noise gating, or spectral editing— to isolate and eliminate or attenuate the background noise, thereby enhancing the quality and fidelity of the primary audio content.

In the field of audio engineering, background noise is typically quantified in terms of its signal-to-noise ratio (SNR). This measurement compares the level of the desired signal (e.g., speech, music) to the level of unwanted noise. A higher SNR indicates a cleaner, more desirable signal, where the noise is less intrusive. Conversely, a lower SNR means that background noise is more prominent, which can detract from the overall quality of the audio.

Having established what background noise is and how it can affect the overall quality of your videos, let's now delve into the methods for effectively eliminating it. Whether you're editing on a desktop or mobile device, there are powerful tools and techniques available to reduce or remove unwanted noise from your video audio. In the following section, we'll guide you through the process of noise removal, providing solutions for both desktop and mobile platforms to ensure your audio is crisp, clear, and professional.

How to Remove Video Background Noise with AI

Step 1. Free download VideoProc Converter AI, click on the the "Audio AI" icon on the main interface, which will bring you to the Audio AI workplace.

Step 2. Upload your file. You can choose to import either an audio file or a video file that includes audio.

Step 3. Apply AI Noise Suppression and preview

Check Noise Suppression, choose the preferred AI model, and adjust the Noise Attenuation Limit, Post-Filter Threshold, and Volume Control accordingly.

• Noise Attenuation Limit (dB): This setting determines the maximum noise suppression level. A higher limit removes more noise but may reduce audio quality, while a lower limit preserves natural sound. For optimal results, set it to 6-12 dB for light reduction and 18-24 dB for moderate noise suppression.
• Post-Filter Threshold: This controls additional noise removal after the initial suppression. A lower threshold (0.01-0.02) offers lighter filtering for quieter environments, while a higher threshold (0.03-0.05) targets moderate noise, such as background hum or chatter, ensuring clarity in the main audio.
• Volume Control: This feature allows users to adjust audio levels. If noise reduction causes a drop in volume, users can increase the signal to enhance clarity and overall enjoyment of the content

Tips:

• For a clear before-and-after comparison, you can toggle off Noise Suppression to listen to the original audio, then turn it back on to hear the enhanced version.
• Click "Apply to All" to apply your changes to all audio files in your project.

Step 4. Export your audio.

Once you're satisfied with the result, you can choose to export the entire file or use the green knobs at both ends of the audio waveform to trim and export only the selected portion.

Adjust the video/audio codec, quality, and GOP as needed, select the destination folder, and click the Run button to export the file with enhanced audio.

2. Adobe Premiere Pro

Adobe Premiere Pro is a widely recognized professional video editing software that offers a range of tools for audio enhancement, including effective background noise removal features.

Tips to Reduce Background Noise When Shooting Video

While noise removal software and apps are a great way to clean up audio in post-production, taking steps to minimize background noise during filming can make a big difference in the quality of your recordings. By controlling the environment and using the right equipment, you can reduce the amount of noise that needs to be removed later. Here are some tips to help you reduce background noise when shooting video, ensuring your audio starts off as clean as possible:

• Choose a Quiet Location: Select a filming location away from noisy environments like busy streets, construction sites, or crowded areas. Opt for quiet indoor spaces or areas with natural soundproofing, such as rooms with carpets or curtains that absorb sound.
• Use a Directional Microphone: Invest in a directional microphone (such as a shotgun mic) that focuses on capturing sound from a specific source while rejecting unwanted noise from the sides or rear. This will help isolate the subject's voice and minimize ambient noise.
• Control the Environment: Turn off or move away from sources of unwanted noise, such as air conditioning, fans, or electronic devices. Close windows and doors to block out external sounds and reduce echo in the room.
• Shoot in a Controlled Environment: If possible, use a controlled soundproof room or studio where you can better manage audio conditions. Consider using foam panels or acoustic treatments to reduce reflections and minimize background noise.
• Monitor Audio in Real-Time: Use headphones to monitor your audio while filming. This will help you catch any background noise or audio issues early on and make adjustments before recording is complete.
• Record Separate Audio: If background noise is a persistent issue, consider recording audio separately using a portable recorder or digital audio interface. You can sync the clean audio with the video in post-production for better quality.

By implementing these techniques, you can significantly reduce background noise and ensure your video audio is clean and professional.
