Video EditorOpen the editorReduce background noise in your audio
Noisy recordings sound unprofessional and hurt captions. Noise reduction lowers constant noise like hiss, fans and room tone while keeping speech.
1Select the clip
Click an audio clip on the timeline, or a video clip with sound.
2Set the amount
In the right panel under Audio, drag the Noise slider. 70% is a good start. Higher values remove more but can sound thin.
3Press Reduce background noise
The app makes a cleaned copy of the sound and keeps the original. For a video, its sound is first split into its own layer.
4Listen and compare
Play the result. If it sounds too processed, undo and try a lower amount.
Tips
- This works best on steady noise (fans, hiss, hum). It cannot remove other people talking.
- Clean the audio before generating captions for better accuracy.
