EraseNoise is an online tool that lowers the noise behind a voice in an audio or video file. On 24 real recordings from the Microsoft DNS Challenge, the background score rose from 2.45 to 4.13 out of 5, and overall quality from 2.14 to 3.18.

Skip the export, clean, and re-sync loop
Cleaning a video usually means exporting the audio, cleaning it somewhere else, and lining it back up by hand. EraseNoise takes the video itself.
The usual way
5 steps- Export the audio from your video
- Upload it to a noise remover
- Download the cleaned audio
- Import it and line it up with the picture by hand
- Render the whole video again
With EraseNoise
3 steps- Upload the MP4 or MOV you already have
- Compare 30 seconds, original and cleaned
- Download the same video with a clean soundtrack, or a WAV for your timeline
Why choose EraseNoise to remove background noise from audio and video
A desktop editor asks you to learn the software first. EraseNoise asks you to listen to 30 seconds of your own file first.
Upload the video, not just the audio
Drop in an MP4, MOV, M4V, or WebM straight from your phone or camera, up to 2 GB. You do not export the audio first.
The picture comes back untouched
Only the soundtrack is replaced. H.264 and HEVC footage from phones and cameras is copied as it is, not re-encoded, so there is no quality loss and no second render.
A WAV that drops onto your timeline
Pick WAV audio for any video: 48 kHz, the same length as the clip, starting at 00:00. Place it at the first frame in Premiere, DaVinci Resolve, or CapCut and mute the old track.
A voice that still sounds like the speaker
Set the noise reduction strength yourself. Keep a little room tone instead of the hollow sound of cleanup pushed all the way.
Hear your own file before you pay
The 30-second preview plays your clip, picture included, with an original and cleaned switch. 3 previews a day without an account, 20 with one.
Pay by the minute
Buy a minute pack once and use it when a noisy take comes up. Pack minutes never expire. Pro adds 20 hours a month for weekly shows.
Built for the way you record
Whatever you record on, the cleanup works the same way: upload the file you already have, hear a preview, and keep the version that sounds better.
For YouTubers & short-form creators
Shot on a phone at a café, on the street, or next to a fan? Post it without opening an editor.
- Upload the MP4 or MOV straight from your phone. No exporting audio first.
- The picture is not re-encoded, so your video comes back looking exactly as it did.
- Upload, preview, and download all work in your phone browser.
- Coming soonKeep your original format: MOV in, MOV out.
For podcasters
Remote guests record in kitchens and echoey rooms. You do not have to book a new session.
- Turn the strength down to keep a little room tone, so the voice stays natural instead of robotic.

- Preview the cleanup against the picture, with an original and cleaned switch.
- Coming soonBatch processing and multitrack output.
The noise that makes a take hard to use
Most voice recordings fail because a steady sound sits under the speech. The words were fine. The room was not. This is the page to remove background noise from audio when that sound is steady.
Wind
Gusts on a phone or an outdoor talking-head sit on top of the voice. This is a real windy clip recorded outside, before and after.
Remove wind noise from videoFan and air conditioning
A fridge, laptop fan, or AC adds a constant whir. This is a real air conditioner under a voice, before and after.
Remove fan noise from audioTraffic
Street wash and passing cars sit under a window or street recording. This is real traffic under a voice, before and after.
Remove traffic noise from audioHum and hiss
Electrical buzz and microphone hiss are low and constant, like a fan. Lowering them helps only if the voice does not turn thin.

Which tool to use
This page is the place to remove background noise from audio when wind, fans, traffic, or hum sit behind a voice.
| Job | Use |

| Wind, fan, traffic, or hum behind speech | This page |
| Speech is hard to hear and you want to set the level | Speech audio enhancer |
| One counted echo | Remove echo |

| Splitting a song into a vocal and an instrumental | Not supported |
When is EraseNoise not the right tool?
EraseNoise does one job: it lowers noise behind someone talking in a file you already have. These cases fit another tool, or need a retake.
Typing on top of the words
In our keyboard sample the scores barely moved: overall quality went from 2.63 to 2.70. Keystrokes that land on a word can stay audible.
Other people shouting or laughing
Another voice is speech too. In the yelling and laughing samples the background dropped, but the voice scored under 3 out of 5 for naturalness.
Splitting a song
EraseNoise does not separate a vocal from an instrumental. Music under someone talking belongs on Remove Background Music.
Several audio tracks in one file
A video with several audio tracks gets one of them cleaned. Mono and stereo stay as they are; a file with more than two channels comes back as stereo.
A clipped or distorted voice
Noise removal cannot rebuild words that clipped or broke up while recording. Re-record when you can.
A live call
EraseNoise cleans a saved file. For a call in progress, use the noise setting in Zoom, Teams, Discord, or Krisp.

How much it costs
Monthly and yearly prices stay visible together. You pay after the preview sounds right and you keep the full file. Pro includes 20 hours a month, not unlimited cleaning.

Frequently asked questions
How do I remove background noise from audio?
To remove background noise from audio in EraseNoise, upload the recording at the top of this page and compare a 30-second preview before paying for the full file. Download the full file only if the cleaned voice sounds better than the original. The same steps delete background noise from the soundtrack of a video.
Can I upload a video directly?
Yes. Upload an MP4, MOV, M4V, or WebM up to 2 GB. EraseNoise cleans the voice and puts the soundtrack back on the same video. H.264 and HEVC pictures are copied as they are; WebM and other codecs MP4 cannot hold are converted to H.264. You do not export the audio first.
Can I put the cleaned audio back in my own editor?
Yes. For a video, choose WAV audio before you download. The WAV is 48 kHz and the same length as the clip, starting at 00:00, unless you trim it. Place it at the first frame in Premiere, DaVinci Resolve, or CapCut and mute the original track.
What noise can EraseNoise lower?
As an audio background remover, EraseNoise lowers noise behind speech: wind, fans, air conditioning, traffic, and hum, and in our tests also a barking dog, a baby, breathing, and kitchen sounds. Keystrokes on top of a word and other people shouting are weak cases. It does not split a song. A counted echo belongs on Remove Echo. A dense room wash belongs on Remove Reverb. Music under speech belongs on Remove Background Music.
How well does EraseNoise remove noise?
On 24 real recordings from the Microsoft DNS Challenge, the DNSMOS background score rose from an average of 2.45 to 4.13 out of 5, and overall quality from 2.14 to 3.18. Dogs, fans, traffic, and scrubbing dropped the most. Typing under a word barely changed. Every recording and its scores are on the noise removal examples page.
Is EraseNoise a free background noise remover?
No. The 30-second preview is free: 3 previews a day without an account, and 20 a day with one. The complete file uses paid minutes. Pro includes 20 hours per month. It is not an unlimited plan. Silence removal is a separate free tool.
Which formats does EraseNoise accept?
Audio uploads can be MP3, WAV, M4A, AAC, OGG, Opus, or FLAC, and the cleaned download is WAV. Video uploads can be MP4, MOV, M4V, or WebM, and the download is MP4.
Is this faster than a desktop editor?
It is faster to try. You do not build a noise profile first, and you can judge 30 seconds of the recording before processing the rest. Audacity or Premiere Pro still fits when you need a manual mix, keyframes, or a full edit.
What happens to an uploaded file?
EraseNoise deletes the upload and the result automatically 24 hours after upload. Files are not kept as public demos.
Does EraseNoise work without installing software?
Yes. You can remove background noise from audio in a desktop or mobile browser. You can hear a 30-second preview without an account. Processing the full file needs an account and paid minutes.
Is EraseNoise the same as RemoveNoise or Denoisely?
No. EraseNoise is only at erasenoise.com. It is not affiliated with RemoveNoise (removenoise.net), Denoisely, or other noise removers with similar names.
