Best for steady background noise. This reduces constant hiss, hum, fan and air-con noise on voice recordings, all in your browser with nothing uploaded. It removes low rumble and quietens the background during pauses. It is not a magic remover for loud, sudden or changing noise, music, or several people talking at once, and very strong settings can make speech sound a little processed. The result downloads as a WAV.
Background Noise Remover reduces steady background noise such as hiss, hum and fan noise on voice recordings entirely in your browser, with nothing uploaded. It removes low rumble and lowers the background during pauses, lets you compare before and after, and downloads the cleaned audio as a WAV.
Frequently asked questions
Is my audio uploaded?
No. The audio is decoded and cleaned entirely in your browser on your device, so nothing is uploaded and it works offline.
What kind of noise does it remove?
Steady background noise such as hiss, mains hum, fans and air conditioning on voice recordings. It removes low rumble and lowers the background during quiet gaps so speech stands out more.
What it cannot do
It is not a magic filter for loud, sudden or changing noise, background music, or several voices at once. For those, results will be limited.
Which formats can I use?
Any audio your browser can open, including MP3, WAV, M4A and OGG. The cleaned file is saved as a WAV, which is lossless and plays everywhere.
How do I get the best result?
Start on Medium and compare with the original using the two players. Use Light if speech starts to sound processed, or Strong for noisier recordings. Keep Remove rumble on for hum and low background.
