How to fix background noise in videos with AI technology?

In today's digital age, video production has become more and more popular, but the problem of background noise has become increasingly prominent. Noise not only ruins the overall look and feel of the video, it can also affect the viewer's understanding and experience. Fortunately, with the help of artificial intelligence technology, we can effectively repair the background noise in the video and improve the video quality. This article will introduce several effective methods to help you solve this problem.

1. Understanding background noise

First, understanding the source of background noise is key to solving the problem. Common background noise includes wind, traffic noise, electrical current generated by equipment, etc. These noises usually appear during video recording and are difficult to avoid. Therefore, it becomes necessary to use technical means for post-processing.

2. Use professional software to repair background noise

There are many professional software on the market that can help us remove background noise from videos, such as Adobe Premiere Pro, Final Cut Pro, and Audacity, which is specialized in audio processing. Let's take Audacity as an example to explain how to operate in detail:

Audacity usage tutorial

1. Download and installation: Visit the Audacity official website (https://www.audacityteam.org/), select the appropriate version according to your operating system, download and install it.

2. Import video files: After opening Audacity, click "File" > "Import" > "Audio" and select the video file you want to edit. It should be noted that Audacity mainly deals with audio, so the audio in the video needs to be separated first.

3. Select the noise sample: On the imported audio track, find a segment with only background noise and select this audio.

4. Capture noise signatures: Click Effects > Noise Removal on the menu bar, then select Get Noise Profiles.

5. Apply the noise removal effect: Select the audio clip containing noise again and repeat the above steps, but select "Remove Noise" in "Noise Removal". Adjust parameters until satisfied.

6. Export the processed audio: Finally, export the processed audio to a new file format, such as MP3 or WAV.

7. Resynchronize audio and video: Since the processing process may have changed the audio duration, the processed audio needs to be re-synchronized with the original video. This step can be accomplished using professional video editing software such as Adobe Premiere Pro.

3. Use AI technology to repair background noise

In addition to traditional audio processing software, artificial intelligence technology that has emerged in recent years has also shown great potential in background noise restoration. For example, the Deshaker plug-in is a tool based on AI algorithms that can intelligently analyze and eliminate background noise in videos. It supports a variety of video formats and has a user-friendly interface that is easy to use.

Deshaker plug-in usage tutorial

1. Download and installation: Visit Deshaker’s official website (assumed URL) and download the plug-in that suits your editing software version. Follow the instructions to install into your video editing software.

2. Import video files: Import the video to be processed into video editing software that supports this plug-in.

3. Run Deshaker: Find the Deshaker plug-in in the software, start it and set the parameters. Generally, you'll get good results by keeping the default settings. For complex videos, some parameters may need to be adjusted manually.

4. Preview and export: After completing processing, preview the video to ensure that background noise has been effectively eliminated. Export the final video file when you are satisfied.

4. Summary

With the above methods, you can effectively fix the background noise problem in your videos. Whether you use traditional audio processing software or emerging AI technology, you can achieve good results. It’s worth noting that in practice, it may take several attempts and adjustments to find the solution that best suits your needs. I hope the information provided in this article will be helpful to you and make your video works more perfect.
