Before and After: 24 Real Recordings, 2.45 → 4.13
How do I compare the original and cleaned audio?
Every upload gets a free 30-second preview of your own file, original and cleaned, before you pay. To hear what that sounds like first, play these six real noisy recordings and switch between the two versions.
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.
All 24 recordings and their scores are in the before-and-after noise removal examples.

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 a Noise Remover Beats an EQ or a Noise Print
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.

- 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 hit a phone or camera mic outdoors: a beach walk, a rooftop interview, a talking-head on a windy street. They land as low thumps and rumble on top of the words. After cleaning, the gusts drop back and the voice stays in front. For windy phone footage, upload the MP4 or MOV itself and get the same clip back with the picture untouched. This is a real windy clip recorded outside, before and after.
Remove wind noise from videoFan and air conditioning
A laptop fan, a fridge, a desk fan, or an air conditioner adds a constant whir under the voice, most often in home offices and bedrooms. Because the sound is steady, it is one of the easiest noises to lower: the whir falls away and the voice keeps its tone. A screen recording or a vlog shot next to the AC goes in as the video itself. This is a real air conditioner under a voice, before and after.
Remove fan noise from audioTraffic
Passing cars, buses, and the wash of a busy road leak into street interviews, calls by an open window, and walk-and-talk vlogs. The steady road noise drops under the voice, so the words no longer compete with the street. A horn that lands on a word is the hard case, so listen for it in the preview. Street footage from a phone goes in as the MP4 or MOV, with no export first. This is real traffic under a voice, before and after.
Remove traffic noise from audioHum and hiss
Electrical hum from a ground loop, a fridge, or lights, and the hiss of a cheap mic or a gain set too high, are low and constant, like a fan. They show up on USB mics, camera audio, and older recordings. Lowering them helps only if the voice does not turn thin, so compare the 30-second preview before you download. Camera footage with hum goes in as video, and the picture comes back unchanged.

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 |
| A voice is hard to hear in audio or video | AI audio enhancer |
| One counted echo | Remove echo |
| A dense room wash | Remove reverb |
| Music under someone talking | Remove background music |
| Long pauses | Remove silence. It is free and runs in the browser. |
| Splitting a song into a vocal and an instrumental | Vocal remover |
Need the vocals and the instrumental separately?
Splitting a song is a different job from cleaning a voice. These tools pull the singing and the music of a finished song apart, so you can keep either one.
Vocal remover
Split a song into the instrumental and the vocals, and download either track or both as WAV.
Instrumental maker
Turn a finished song into a backing track. Every voice comes out, harmonies included.
Acapella extractor
Lift the singing out of a song with its original timing, ready to line up in a remix.
Remove vocals from a song
Take the voice out of a song you already have and keep the bass, drums, and chords.
Karaoke maker
Drop the lead singer, keep the harmonies and the band, and blend some of the lead back as a guide.
When is EraseNoise not the right tool?
This page 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.
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.

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 remove background noise from a video without exporting the audio?
Yes. Upload the MP4, MOV, M4V, or WebM itself, up to 2 GB; you do not export the audio first. EraseNoise cleans the voice and puts the soundtrack back on the same video. H.264 and HEVC pictures are copied as they are, so the picture is not re-edited; WebM and other codecs MP4 cannot hold are converted to H.264. The video noise remover covers camera and phone footage in more detail.
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. To split a song into vocals and an instrumental, use the vocal remover. 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?
Partly. The 30-second preview of any file is free: 3 previews a day without an account, and 20 a day with one. Every new account gets 1 free minute: a file up to a minute downloads whole, and a longer one as a free 1-minute excerpt. Longer files use paid minutes: each file is rounded up to the next whole minute, and minutes from a pack never expire. Pro includes 20 hours per month, which reset each billing period; it is not an unlimited plan. Prices are on the pricing page. Silence removal is a separate free tool.
What file formats and sizes can I upload?
Audio uploads can be MP3, WAV, M4A, AAC, OGG, Opus, or FLAC. Video uploads can be MP4, MOV, M4V, or WebM. Each file can be up to 2 GB. Cleaned audio downloads as WAV. A video downloads as an MP4 with the same picture and a cleaned soundtrack, or as a 48 kHz WAV for your timeline; this guide shows how to line the WAV back up.
How is this different from noise reduction in Audacity or Premiere Pro?
Audacity's Noise Reduction asks you to select a stretch of noise alone, save it as a noise profile, and tune the strength by ear. In Premiere Pro, DeNoise and Enhance Speech run inside an edit you open first. EraseNoise needs no noise profile: upload the file and judge 30 seconds of your own recording before processing the rest. Audacity or Premiere Pro still fits when you need a manual mix, keyframes, or a full edit. Step-by-step guides: noise reduction in Audacity and noise reduction in Premiere Pro.
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.
Can I remove background noise on my phone without an app?
Yes. EraseNoise runs in Safari or Chrome on an iPhone or Android phone, and in any desktop browser, with nothing to install. Pick the video or voice memo from your camera roll or files, play the 30-second preview without an account, and download the cleaned MP4 or WAV back to the phone. Processing the full file needs an account; the first minute is free when you sign up. To lower noise while you record instead, see Voice Isolation on iPhone.
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.
