GOOD QUESTIONS. CLEAR ANSWERS.

A little less uncertainty.

Everything to know before you hit clean.

How do I remove background noise from audio?

Choose an audio or video file, click Clean my audio, and listen to the before-and-after previews. Download the cleaned audio as WAV or MP3. RNNoise reduces noise locally on your device.

Does my audio leave my device?

No. Audio is read, decoded, cleaned and encoded inside your browser. DenoiseKit does not send your recordings to a server, and this MVP has no analytics or third-party tracking.

What kinds of noise can AI reduce?

RNNoise is designed for speech. It can reduce steady background noise such as fans, hiss and hum. Loud overlapping voices, clipping, room echo and music are harder to fix. Results vary; always compare the previews.

Which audio and video formats work?

You can select WAV, MP3, M4A, OGG, MP4, WebM or MOV files. Actual decoding depends on your browser and the codecs inside the file. If a video cannot be decoded, export its audio as WAV or MP3 and try again. Video output is not supported.

Is DenoiseKit free to use?

The free tool allows up to 3 files per local calendar day, each no longer than 5 minutes. No account is needed. Paid plans are coming soon and do not unlock extra usage yet.

Will my recording stay stereo?

No. DenoiseKit mixes the recording down to mono and resamples it to 48 kHz for RNNoise. Downloads are 16-bit mono WAV or 128 kbps mono MP3. Keep your original file.

Let your voice do the talking.
