Remove background noise from audio
Choose an audio or video file with speech and an AI noise filter cleans it on your device. Nothing is uploaded.
For speech: voice notes, interviews, podcasts, classes. You get a WAV at 48 kHz.
Your recording never leaves your device
How to do it
- Choose the audio file (MP3, WAV, M4A, OGG…) or the video (MP4, MOV, WEBM).
- Press "Remove noise" and keep the tab open while the bar fills.
- Compare before and after, then download the WAV.
Tips
- It works best on speech with steady noise behind it. Loud sudden sounds, such as a door slam, may stay.
- A video? Its sound is cleaned and saved as a WAV; put it back in your video editor.
- Very noisy recording? The voice can sound a little thinner afterwards: compare before and after.
Questions
Is my recording uploaded to a server?
No. The noise filter runs in your browser and the file stays on your device. Nothing is sent anywhere.
Which files work?
Whatever your browser can play: MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, and the sound of MP4, MOV and WEBM videos.
Why is the result a WAV?
WAV keeps the cleaned sound with no further loss and opens in every editor and player. It is larger than an MP3.
Does it work with music or singing?
No. The filter is trained on speech: it keeps voices and removes the rest, so music comes out damaged.
How long does it take?
On a current computer, a minute of audio usually takes a few seconds. Long recordings need a lot of memory: on a phone, keep them under about 30 minutes.
