AI Background Noise Remover for Video and Audio
Drop in a noisy clip and the AI strips the hiss, hum, wind, traffic and room rumble sitting behind the voice, so what is left is the speech and not the place you recorded it. You get the video back with the picture untouched. It runs free in your browser, on this device: nothing is uploaded and no account is needed. For a long recording, switch to Cloud: your first 10 credits are free, which is 10 minutes here, no card needed.

The noise remover runs on this device's processor in your browser and your file is never uploaded, so the ceiling is minutes of audio. For longer files, .
Cleanup strength
Removes hiss, hum, wind and traffic and leaves a trace of the room, so the recording still sounds like a place.
Free on this device where the model can run. In the Cloud, you pick how long the result is kept.
Bigger files? Run it in the Cloud
This tool runs on this device for free. For a file over the device limit or a long recording, the same tool runs on our servers, with up to 500 MB per file and 1 hour of audio, faster, and with your files kept for up to 7 days, or as long as you choose with any pack or plan. From 1 credit a minute, with 10 credits free when you create an account.
How to remove background noise from a video
Drop in the file and the AI separates the speech from the noise around it. Fans, air conditioning, traffic, wind and crowd rumble drop away and the voice comes back clear.
- Drop in an MP4, MOV, MKV or WebM, or an MP3 or WAV.
- The AI cleans the noise off the speech.
- Preview it, then download the cleaned file.
Why this beats a noise filter
A gate or a denoiser plugin guesses at a noise profile and subtracts it, which is why heavy settings leave voices sounding underwater. This model was trained on speech, so it knows what to keep.
The voice still sounds like a voice
Traditional noise reduction thins and warbles speech when you push it. Separating the voice from the noise avoids that, so it stays natural instead of processed.
Handles noise that changes
A gate only copes with steady hiss. Traffic passing, a door slamming, a crowd shifting: this deals with noise that moves, which is most real-world recording.
Video in, video out
Drop a video and you get a video back with the picture untouched, instead of a bare audio file you have to line up again in an editor.
One choice, no knobs
There is no threshold, ratio or noise profile to capture. Pick Light, Balanced or Full and the model decides the rest, which is the whole point if you are not an audio engineer.
Rescues one-take recordings
An interview you cannot reshoot, a speech from the back of a hall, a phone clip from a busy street. These are the files worth paying to save.
Free to try on a real file
Every account starts with 10 credits for free, which is 10 minutes of this tool: enough to run a genuine clip rather than a sample. No card needed.
How it works, step by step
Four steps from a noisy recording to clear speech.
Add your file
Drag a video or audio file onto the box above, or click to browse. MP4, MOV, MKV and WebM all work, as do MP3, WAV and M4A.
Pick This device or Cloud
This device runs the model in your browser: free, no account, nothing uploaded, on any modern browser, up to 15 minutes of audio per file. The Cloud runs it on our servers for longer files: sign in, and your first 10 credits are free.
Let the model clean the audio
It listens to the whole track and pulls the speech away from the noise behind it, rather than filtering a frequency range and hoping.
Preview, then download
Check the result before you commit. If the voice is clear, download the file and use it.
What people use it for
Recordings where the words are fine but the place you made them is not.
Interviews recorded in the wrong room
Air conditioning, a fridge humming, a fan in the corner. Steady noise you never noticed while recording and cannot stop hearing afterwards.
Outdoor filming
Wind across the microphone, traffic, a plane going over. Take the location out and keep the piece to camera.
Podcast guests on bad connections
Line hiss, a noisy laptop fan, a room with nothing soft in it. Even out the episode so listeners hear the conversation.
Talks filmed from the audience
Coughing, shuffling, chatter from the row behind you. Pull the speaker forward out of the crowd.
Phone clips worth keeping
A moment you only caught once, on a busy street. Clean it up rather than lose it.
Audio going to transcription
Noise wrecks automatic captions. Cleaning first is cheaper than fixing a bad transcript by hand afterwards.
What it handles well, and what it does not
| Works well on | Not what it is for |
|---|---|
| Steady hiss, hum and fan noise | A music track mixed under the voice |
| Wind, traffic and street noise | Echo and reverb from a hard room |
| Crowd rumble and background chatter | Audio already clipped or badly distorted |
| Line noise on a remote recording | Speech buried under noise as loud as the voice |
Which of our AI audio tools you want
| The problem | Use this |
|---|---|
| Hiss, hum, wind, traffic or a noisy room behind the voice | This tool. Built for noise, and only noise. |
| A music track playing behind your talking | Background Music Remover. Noise removal will not reliably take music out. |
| You want the speech on its own, out of a full mix | AI Voice Isolator. A true separation rather than a cleanup. |
| You want the music and not the voice | AI Vocal Remover. Returns the soundtrack with the vocals removed. |
| Every sound gone | Mute Video, on the homepage. Runs on this device, no upload, no account. |
The honest boundary: this cleans noise off speech. It is not a music remover and it does not remove echo or reverb from a room, which are different problems with different fixes.
Is it music behind the voice rather than noise? The background music remover takes it out; the AI voice isolator is the same model for any recording where only the speech matters.
