Frequently Asked Questions
- How do I remove background noise from a video?
- Upload your video, choose a noise reduction strength, and click Process. The FFT-based denoiser analyzes the audio and removes consistent background noise like hiss, hum, and ambient sounds.
- What types of noise can this remove?
- This tool works best on consistent background noise — fan hum, air conditioning, electrical hiss, and ambient room tone. It's less effective on intermittent noises like dog barks or door slams.
- Will it affect the voice or music quality?
- Light and medium settings preserve voice clarity well. Heavy reduction removes more noise but may slightly affect audio quality. Start with medium and adjust if needed.
- Is this audio denoiser free?
- Yes, completely free with no watermarks or limits. All processing happens locally in your browser — your files are never uploaded to any server.
