Audio & Video Noise Remover is a free, browser-based tool that reduces steady background noise (hiss, hum, fan noise) using FFmpeg's FFT-based denoise filter. This is a signal-processing filter, not a neural/AI noise removal model — it works best on steady, consistent background noise rather than complex or intermittent sounds.
How to use the Audio & Video Noise Remover
- Upload an audio or video file.
- Adjust the noise reduction strength.
- Click Remove noise \u2014 the first use downloads the processing engine (~30MB), cached afterward.
- Download the cleaned-up file once processing finishes.
