Remove Noise From Video – AI Audio Denoiser

This extension is an on-device AI audio denoiser that helps you remove background noise from video: hiss, hum, fan/AC noise, keyboard clicks, and room echo — while keeping voices clear. Processing runs locally in your browser (hardware-accelerated / WASM) and can be up to 10× faster than real time, so a 20-minute video may finish in ~2 minutes.*

Video audio denoise features

- Denoise video audio in one click — select a file and press Process Media
- On-device noise reduction (privacy-first) — your media stays on your computer (no server uploads)
- AI noise suppression for speech — improves voice clarity and reduces background noise
- Fast audio cleanup — up to 10× faster than playback (depends on hardware/codec)
- Works with common formats — MP4, MOV, MKV, WebM and more (containers/codecs vary)
- Preview before export — A/B switch to compare original vs denoised audio

*Actual speed depends on your CPU/GPU, browser, and the file’s codec/bitrate/length.

How to remove noise from a video
- Open the extension and choose your video file (MP4/MOV/MKV/WebM, etc.)
- Click Process Media to start on-device denoise
- Preview the cleaned result (adjust options if needed)
- Click Download Processed Media to save the video with cleaner audio

Why choose this AI video audio cleaner?
- Privacy-first: everything runs locally — no uploads, no accounts
- Saves time: faster-than-real-time noise reduction for longer videos
- Voice-focused quality: modern AI model tuned for speech clarity
- Zero friction: works entirely in Chrome — no installers or logins

Great for
- YouTube creators, course makers, and webinar recordings
- Sales/support teams cleaning call recordings
- Students & teachers cleaning lectures
- Podcasters and interviewers fixing room noise
- Anyone who needs clean audio in video before sharing or archiving

Privacy & permissions
- On-device processing only: the extension does not upload or send your media anywhere
- Minimal permissions: access only to files you open, plus download permission to save results

Troubleshooting
- File won’t open? Convert to a common format (MP4 H.264/AAC or WebM VP9/Opus) and try again
- No sound in export? Confirm the source file contains an audio track
- Slow on large files? Close heavy tabs/apps, or export audio-only for a lighter workflow
- Browser memory limits: very long or high-bitrate files may need splitting before denoising
