One click cleans the whole file on your device with a small neural noise-suppression engine (about 0.1 MB, size shown before the one-time download, cached for next time).
Remove Background Noise from Audio - AI, In Your Browser
Remove steady background noise - hiss, hum, fan, street rumble - from a voice recording without the audio ever leaving your browser.
Key features
- Two side-by-side players to compare the original and the cleaned version before you download anything.
- A no-download Basic cleanup mode - a rumble filter plus a pause gate - for an instant result on any browser.
- The cleaned file downloads as a mono 48 kHz WAV, whatever format you loaded.
Noise it handles - and its limits
The engine is tuned for one speaking voice over steady noise: hiss, hum, a fan, street rumble. It will not rescue loud overlapping speech or sudden bangs, and it is not a music mastering tool. The Basic cleanup mode is honestly labeled below the AI path because it does much less against hiss and babble.

If you need a different format afterwards, the audio converter can re-encode the WAV. To turn the cleaned speech into text, the speech to text tool runs on your device too. And if the problem is long pauses rather than noise, the silence remover cuts the dead air automatically with the same on-device engine family.
Frequently Asked Questions
Does my recording get uploaded anywhere?
No. The file is decoded and cleaned entirely on your device. The only download is the noise-removal engine itself - about 0.1 MB, fetched once after you click the AI button and cached for next time.
What noise can it remove - and what can it not?
It is built for steady background noise behind one speaking voice: hiss, hum, fan noise, street rumble. It cannot separate loud overlapping speech, undo clipping, or fix sudden bangs, and it is not a music mastering tool - music and vocals lose quality.
What format does the cleaned file come out as?
Always a mono 48 kHz WAV, whatever you loaded (MP3, WAV, M4A, OGG, FLAC and other formats the browser can decode). Re-encode it with the audio converter on this site if you need a different format.
What is the difference between the AI button and Basic cleanup?
The AI button runs a small neural noise-suppression engine on your device and is the real cleanup. Basic cleanup needs no download at all: it applies a rumble filter and quiets the pauses, which helps, but it does much less against hiss and babble.
