Hear the difference
Hear the audio cleanup across noise types
Every clip uses the same demo footage on purpose — so nothing in the picture distracts from the actual comparison: how the audio track changes after Denoisr.
Identical demo footage on both sides — focus on the audio track.
Bus-cabin noise
Audio: low engine rumble + cabin vibration + occasional stop announcements. The classic travel-vlog noise floor — steady mechanical hum is the kind Denoisr handles most reliably.
What to listen for
We use one shared demo clip across every sample so the picture doesn't get in the way. Toggle Before / After and pay attention to what Denoisr does to the audio.
Picture untouched
Frames, frame rate, and resolution stay identical before and after — only the audio track is remixed.
Same clip, swapped audio
Both sides play the same demo footage. The only thing that changes between Before and After is whether the audio went through Denoisr.
Pick the closest noise type
Bus, cafe, home, office, outdoor — choose the noise that's closest to what you actually record around.
What it cleans
Three cleanup modes built for video
Pick one mode or stack all three — our AI engine only touches the audio track, your picture stays exactly as it was.
Clean Noise
Strips out background hum, AC, fan whirr, keyboard clack, traffic, and room echo without dulling the voice — ideal for home-office shoots, vlogs, and outdoor recordings.
Enhance Voice
Lifts vocal clarity, balances loudness, and adds studio-grade polish — best for thin, muffled, or boomy recordings where the voice needs to feel closer and more confident.
Podcast Ready
Trims filler words (um, uh), long silences, mouth sounds, breaths, and stutters — perfect for video podcasts, interviews, and shows you want shipped faster.
How it works
From upload to cleaned download in four steps
Your video uploads to the closest Denoisr edge node, so even 1GB files move quickly. Source files are automatically deleted within 24 hours.
Upload your video
Drag and drop or pick MP4, MOV, M4V, WebM, or MKV up to 1GB. We read the duration locally to estimate cost before you commit.
Pick the modes
Choose Clean Noise, Enhance Voice, or Podcast Ready — combine any to match your footage. Combining modes does not cost extra credits.
Process
Our AI engine analyzes the audio track only. Your picture, codec, and resolution stay untouched.
Compare and download
Play the before and after side by side, then download the cleaned video file directly.
Video Audio Cleaner — questions, answered
What does Video Audio Cleaner actually do — and what does it leave alone?+
It cleans only the audio track inside your video: removing noise, balancing the voice, and optionally trimming filler words and long pauses. Your picture, frames, codec, resolution, and aspect ratio are never re-encoded — only the audio changes.
Will my video lose visual quality after the cleanup?+
No. The video stream is passed through untouched, so the output is pixel-for-pixel identical to your source — just with a clean audio track muxed back in.
Which video formats and file sizes do you support?+
MP4, MOV, M4V, WebM, and MKV, up to 1GB per file. If you upload an unusual container, we automatically read its duration with a browser-side WASM probe — no manual conversion needed before uploading.
How is the cost calculated, and can I see it before I pay?+
Cost is based purely on your video's duration — 1 credit equals 1 minute of video cleanup, rounded up to the next minute. We read the duration in your browser before upload, so the exact charge appears in the review step before you start. Combining multiple cleanup modes does not cost any extra credits.
How long does the cleanup usually take?+
Most short clips (under 5 minutes) finish in 1–2 minutes. Longer files and busy queue times take a little more, but you'll see a live progress indicator the whole way through so you know exactly where it is.
Stop fixing video audio by hand
Upload a video, pick your modes, and download the cleaned result in minutes. Five free credits included so you can try the full flow before paying.
