Your recording comes back with the fan, traffic, wind and room echo gone and the voice as it was — MP4 for a video, 48 kHz WAV for audio — at the noise-reduction level you set.

A song playing under the voice? Remove background music instead.
A background noise remover is an AI speech enhancement tool that lets you remove background noise — hum, fans, traffic, wind, barking — from audio and video while keeping the voice. Vocal Isolator's background noise remover runs NVIDIA's RE-USE model, which also reduces room echo; you set how much noise goes, and videos download as MP4, audio as a 48 kHz, 16-bit WAV.
Press play on a real noisy clip below, then switch between Original and Cleaned. The video keeps running, so you hear the same words with and without the noise. Your own file works the same way: upload it, and the first 30 seconds are cleaned free so you can remove background noise from a short piece before you pay for the whole file.
Remove wind noise from an outdoor video
Same clip, same voice level. Only the noise changes.
We scored 24 real noisy recordings with DNSMOS, a speech quality model from Microsoft that rates audio from 1 (bad) to 5 (excellent), before and after we remove background noise. Six are below, including one where it barely helps; play any of them to hear the original and the cleaned version.

A noisy recording is hard to listen to for a simple reason: the noise plays at the same time as the words. A noise gate only mutes the pauses, so the fan or the traffic comes right back every time someone speaks. EQ cuts whole frequency bands, and most everyday noise shares those bands with the human voice, so cutting it dulls the speech too.
Classic noise reduction, like Audacity's Noise Reduction effect, learns one noise profile from a silent moment. It works on steady hiss and hum, but barking, passing cars, and clattering dishes change every second. To remove background noise that moves, you need a model that knows what speech sounds like and keeps only that.
| Method | How it works | Result on speech | Use it when |
|---|---|---|---|
| Noise gate | Mutes the audio whenever it drops below a level | Quiet pauses, but the noise stays under every word | The noise is soft and only bothers you in the gaps |
| EQ or a high-pass filter | Cuts low or high frequencies | Removes rumble, but dulls the voice if pushed further | The problem is low rumble or mic handling |
| Noise profile (Audacity Noise Reduction) | Subtracts a sampled noise from the whole file | Good on steady hiss; leaves changing noise and can sound watery | One steady hum or hiss runs through the recording |
| AI background noise remover (this tool) | A speech model keeps the voice and drops everything else | Steady and changing noise removed, plus room echo | The noise changes, or you need the result fast |
Upload an MP4, MOV, or other video to remove background noise and download an MP4 with the same picture and a clean soundtrack. You never export the audio and line it back up in an editor.
A Noise reduction slider lets you keep a little of the room for a natural sound, or remove background noise completely. The download uses the level you set.
Turn on Voice polish for studio-style EQ and gentle compression, and the volume is leveled automatically, so a quiet phone recording comes out at a steady, comfortable loudness.
Upload files up to 2 GB from Windows, Mac, Chromebook, iPhone, or Android. The AI runs on cloud GPUs, so you can remove background noise with nothing to install and no graphics card.
The background noise remover runs NVIDIA's RE-USE speech enhancement model, which is trained on speech to keep the voice and drop everything else instead of carving frequencies out of it. When you remove background noise this way, tone and accent stay, and room echo is reduced along with the noise.
A stereo camera mic keeps its left and right balance when you remove background noise, so voices do not wander between speakers. An interview recorded on two mics is cleaned side by side, which also removes most of each mic's bleed from the other person.
The tool keeps speech and can remove background noise that is not a voice. These are the noises it handled well on real recordings we tested, plus room echo, which the same model reduces.
| Noise | Examples |
|---|---|
| Steady machine noise | Fans, air conditioners, dishwashers, copiers |
| Outdoor noise | Wind on the mic, traffic, street wash, a passing car |
| Home noise | Dogs barking, babies, dishes and utensils, doors, scrubbing |
| Mouth noise | Breathing, chewing, and crunching close to the mic |
| Desk noise | Mouse clicks and a creaking chair |
| Room echo | The hollow sound of a bare room, a hallway, or a large hall |
You can remove background noise from most audio and video files without converting them first.

To remove background noise from a video, follow four steps from the upload to an MP4 with a clean voice.
The same steps remove background noise from audio files: MP3, WAV, M4A, and other recordings come back as WAV with the voice kept and the noise gone.
Upload an episode or a guest track recorded in a noisy room or over a laptop mic. Remove background noise from the whole file, then trim the part you need before you download.
A phone memo, a lecture, or a voicemail is easier to follow, and easier for transcription apps to read, once the fan, the traffic, and the hall echo are gone.
You shot a vlog on a windy beach or a busy street and the mic picked up everything. Upload the MP4 and remove background noise before you edit or post.
Result: the same video with wind and traffic removed from the voice.
A guest recorded on a laptop next to a fan, a dog, or a kitchen. Upload their track to the background noise remover and turn on Voice polish.
Result: a clean WAV that matches the rest of the episode.
A lecture recorded in a large classroom echoes and hums. Remove background noise and room echo so students hear every word.
Result: a clearer lecture video or audio file, ready to upload.
Each tool keeps something different. Use this page to remove background noise from speech, and pick the others by what should stay in your file.
| You want | Use | You get |
|---|---|---|
| A clear voice without hum, fans, wind, traffic, or room echo | Remove Background Noise (this page) | MP4 or WAV with the noise removed |
| Speech and sound effects without the music under them | Remove Background Music | MP4 or WAV with the music removed |
| The music from a song, without the singer | Instrumental Maker | An instrumental WAV |
| Both the vocals and the music of a song | Vocal Isolator | Vocals and music as two WAV tracks |
| Remove keyboard typing or running water | Partly | In our tests these barely improved when we tried to remove background noise of this kind; preview your file before you pay |
| Remove other people talking in the background | Not supported | Background voices are speech, so they stay |
| Fix a distorted or clipped recording | Not supported | Removing noise does not restore audio the mic already cut off |

The free preview of the first 30 seconds is usually ready in about 40 seconds, most of it spent cleaning on a cloud GPU. A full file takes longer the longer it is. You can close the page while it runs: full files finish on the server and appear under Your files on this page for 24 hours.
Usually not. The model used to remove background noise is trained to keep speech rather than filter frequencies. Very loud noise right on top of a quiet voice can leave a slightly thin sound. If it does, lower the Noise reduction slider so a little of the room comes back.
Yes. When you remove background noise, the same model also reduces room reverb, so a bare room or a hall sounds closer and drier.
Partly. The noise model keeps speech and lowers most other sounds, but music with singing can stay. To take music out from under dialogue, use the background music remover.
Open the background music removerNo. Upload the file itself, up to 2 GB. If the video is yours, download it from YouTube Studio, TikTok, or your phone first, then upload it here to remove background noise.
No. You can remove background noise in your browser on Windows, Mac, Chromebook, iPhone, or Android. The model runs on cloud GPUs, so you need no app, plugin, or graphics card.
