In fact, audio editing software like Audacity can only well deal with the white noise, which means the constant, predictable, and never changing noise.
But when it comes to other noises like people talking in the background, cars, birds chirping, doors slamming, foot traffic, etc. It's been nearly impossible to remove them while keeping your audio in good quality. So, we recommend masking them instead of trying to fix the issues, and just adding some background music to your video can solve this problem.
In Wondershare Filmora, you can simply drag a song or music in the Music Library into the audio track of your timeline, then edit and adjust its volume, speed, pitch. Then you can cover the background noise without drawing attention away from your dialogue.
You can also try AI music, generating your preferred music based on the scene mode and emotional atmosphere needed for the video. Additionally, you can apply AI sound effects in the editing process to add some interesting effects, making the video more lively.
Similarly, you can try Filmora's Smart BGM Generation, which can identify your video's theme and match it with suitable background music. You can watch the video below for specific instructions.

FAQs about removing audio background noise from video
Have some questions about removing background noise from video audio? Check these answers below.
-
1. What's the difference between Normal Denoise and AI Voice Enhancement in Filmora?
Normal Denoise is best for removing steady, constant background sounds like hums or wind. AI Voice Enhancement is more advanced; it specifically identifies and boosts human vocal frequencies while reducing other competing sounds, making dialogue clearer. -
2. Can Audacity remove complex noises like people talking or cars?
Not effectively. Audacity's Noise Reduction tool works by identifying a consistent noise pattern. Variable, unpredictable sounds like talking or traffic cannot be easily isolated and removed without significantly distorting the main audio. For these scenarios, using a tool like Filmora to either apply smarter noise reduction or mask the sound with music is a better approach. -
3. How to remove background noise from a YouTube video?
You cannot directly edit a video that is already uploaded to YouTube. You must first download the original video file to your computer. Then, import it into a video editor like Filmora, use the steps outlined above to remove the background noise, and finally, re-upload the corrected version to your YouTube channel. -
4. Is it better to use an online tool or desktop software?
For security, quality, and features, desktop software like Filmora or Audacity is almost always better. Desktop editors offer far more control, handle larger files without issue, and don't require you to upload your private footage to a third-party server. Online tools are only suitable for very small, non-sensitive clips or for completely stripping audio.
Conclusion
Now, you have got an audio file with noise reduced or removed. I hope you will find that it is not hard to remove background noise from the video with the solutions provided above. For those who want to make their audio more creative, try Filmora video editor to empower your imagination today.
