Know Your Noise.
Different noises need different fixes. The tool listens first, then tells you what it found.
| Noise | Sounds like | Usually from | What happens |
|---|---|---|---|
| Hum | Steady low tone at 50 or 60 Hz | Fridges, lights, cables | Removed completely |
| Hiss | Soft “shhh” under everything | Cheap mics, high gain, fans | Removed, voice kept bright |
| Room noise | Traffic, air conditioning, people far away | Open windows, offices | Reduced strongly |
| Echo | Voice bounces off bare walls | Empty rooms, bathrooms | Light room sound reduced |
| Clicks and pops | Short sharp sounds | Mouth noise, mic bumps | Softened |
Clean Sound for Every AI Step.
A clean voice makes every AI tool that listens to it work better.
Before Text to Speech
Cloning or matching a voice works far better from a clean sample. Clean your reference recording first.
Before Lip Sync
AI lip sync follows the sound. Noise and echo confuse it and make mouths move at the wrong moments.
Before Transcription
Clean audio means fewer wrong words in Video to Text and in auto captions.
UGC Voiceovers
Phone recordings in a bedroom or car sound professional enough for an ad after one pass.
Podcast Clips
Turn noisy remote-guest audio into something you can post as a short clip.
Product Demos
Remove keyboard and fan noise from screen recordings with a voice on top.

Voice Cleaner removes hum, hiss, fan noise and room sound from voiceovers, podcasts and videos. It’s tuned for speech, so the voice stays clear while everything around it drops away.
Use it before voice cloning, lip sync, transcription or any AI step that listens to a voice. Cleaner input means better results.
Your Recording Is Never Uploaded
The noise model runs in your browser with WebAssembly. It works on long recordings and even offline once the page has loaded.
Nothing is sent to our servers, on Free or on Pro.
Record Better, Clean Less.
The best cleanup is the one you don’t need. Four habits that help any recording.
- 01
Get Close to the Mic
A hand’s width from the mic gives a strong voice and less room. Distance is the biggest cause of echo.
- 02
Soften the Room
Curtains, a sofa, a wardrobe full of clothes. Soft things behind you absorb echo better than any software.
- 03
Turn Things Off
Fans, fridges and air conditioning make steady noise. The tool removes it, but less noise means a more natural voice.
- 04
Record Ten Seconds of Silence
A short pause at the start helps the cleaner learn exactly what your room sounds like.
Cleaned on Your Device.
Noise reduction runs in your browser with WebAssembly. Your recording is never uploaded.
Learn the Noise
The quiet moments between words tell the model what your room sounds like.
Separate Voice from Noise
A small neural network trained on thousands of voices keeps speech and lowers everything else, many times a second.
Level the Result
The cleaned voice is brought to an even volume, ready for video or podcast.
How Much to Clean.
More cleanup isn’t always better. Strong settings can thin out soft words and the end of sentences, so pick the lowest level that removes the noise you hear.
| Level | For recordings made in | What to expect |
|---|---|---|
| Light | Quiet rooms, good mics | Keeps every bit of the voice’s character |
| Medium | Home offices, laptops, phones | Best balance for most voiceovers |
| Strong | Fans, traffic, cafés, cars | Removes the most; check quiet words afterwards |
Listen on headphones at the quietest part of the recording. That’s where too much cleanup shows first.
Cleaning a Voice, Answered.
How do I remove background noise from a voice recording?
Add the file, check what the tool found, and set Clean up to Strong. Switch between A and B to compare, then save.
Is my recording uploaded?
No. Cleaning runs in your browser. Nothing is sent to our servers.
Can I clean the sound of a video?
Yes. Add the video and save its clean sound as WAV or MP3. With Pro, choose Video under Save as: the picture is kept exactly as it was and the cleaned sound replaces the old one.
Will my voice sound robotic?
At Strong it can thin out very quiet words. If you hear that, lower Clean up a step and keep Keep breaths on.
Does it remove music?
It’s made for noise, not music. To separate a voice from music, use a vocal remover first.
Which files work?
WAV, MP3, M4A, FLAC and OGG audio, and MP4, MOV or WebM video.
Does it remove echo?
It reduces light room sound. Heavy echo from empty rooms is best fixed while recording: get closer to the mic and soften the room.
Why clean audio before AI voice tools?
Voice cloning, lip sync and speech-to-text all learn from what they hear. Noise gets copied into the result or causes mistakes.
Is there a length limit?
Up to 10 minutes per file on the free plan, up to 3 hours on Pro.
Can I undo the cleanup?
Your original file isn’t changed. The cleaned version is saved as a new file, so you can always go back and try a lighter setting.
Does it work on a phone?
Yes. Cleaning a few minutes of audio takes seconds on a recent phone.
