How to Remove Background Noise in CapCut (App and PC)

Wind, traffic, a buzzing fridge or a noisy café can spoil an otherwise great video. CapCut has a built-in noise reduction tool that cleans up most everyday background noise in one click. Here's how to use it, how to get better results, and when it's quicker to just re-record.

How to remove background noise in CapCut on a computer

1. Open CapCut, create a project and import your video.
2. Drag the clip to the timeline and click it.
3. In the panel on the right, open the Audio section.
4. Switch on Reduce noise.
5. Play the clip back and listen with headphones.
6. Export when you're happy.

Get more control by separating the audio

If your video has music or several clips, it helps to pull the sound out into its own track first. Right-click the clip in the timeline and choose Separate audio. The sound appears on its own track, where you can use Reduce noise, adjust the volume of quieter or louder sections, or mute parts entirely.

Remove background noise on the CapCut app

1. Open your project and tap the clip in the timeline.
2. Tap Detach if you want the audio on its own track.
3. Look for the noise reduction option in the audio tools at the bottom and switch it on.
4. Play it back and export.

What CapCut's noise reduction is good and bad at

Noise type	How well it works	Better option
Steady hiss, hum or fan	Usually very well	Reduce noise is ideal
Light traffic or air conditioning	Well	Reduce noise, then lower the volume of gaps
Wind hitting the microphone	Partly	A windshield on your mic next time
Music or people talking nearby	Poorly	Re-record somewhere quieter
Sudden bangs or barks	Poorly	Cut that moment or re-record the line

The catch: noise reduction can make your voice sound strange

Noise reduction works by guessing what's noise and what's you, so it can take a bit of your voice with it. If the cleaned audio sounds thin, underwater or slightly robotic, the effect is working too hard on the material it's been given. Listen to the before and after side by side. A little remaining room sound almost always sounds more natural, and more trustworthy, than an over-processed voice.

That's why recording in a quieter spot beats fixing it afterwards. CapCut's own guide suggests simple tricks at home, such as soft furnishings, blankets or curtains, to soak up echo and noise before you hit record.

Tips for cleaner sound before you edit

• Get the microphone close to your mouth. A clip-on mic beats your phone's built-in mic across a room.
• Turn off fans, air conditioning and notifications.
• Record in a smaller room with soft furnishings.
• Use a windshield or foam cover outdoors.
• Record a few seconds of silence before you speak so you can hear the room noise and judge the fix.

Finishing touches

• Add gentle background music under your voice to mask any remaining hiss.
• Lower the music when you speak and raise it when you stop.
• Add captions so viewers can follow even in noisy places.

If exporting becomes slow or fails after adding effects, CapCut recommends lowering the resolution or frame rate and freeing up storage. For more short-form video ideas, see my guides to TikTok Studio and podcast editing software for heavier audio clean-up.

A quick before-and-after test

1. Play ten seconds of the clip with Reduce noise switched off and listen closely to the background.
2. Switch it on and play the same ten seconds again.
3. Listen for your voice: does it still sound like you, or thinner and slightly hollow?
4. Check the gaps between sentences, where noise is easiest to hear.
5. Listen once more on your phone's speaker, since that's how many people will hear it.

If the cleaned version sounds worse, switch the effect off and try lowering the volume of the noisy gaps instead, or add soft background music to cover a gentle hiss. Sometimes the most natural result is a little noise left in, rather than a voice that sounds processed.

When to re-record instead

If people nearby are talking, music is playing in the background or the noise drowns out your words, no editing tool will rescue it cleanly. It's quicker and better to record again somewhere quieter. Keep a short checklist for future recordings: quiet room, mic close, notifications off, test first.

My verdict

Select the clip, open Audio and switch on Reduce noise. That fixes most hums and hisses in seconds. Separate the audio when you need more control, and listen back with headphones so you don't over-process your voice. For noise that's loud, sudden or full of other voices, re-recording is faster than any fix.
