How do I reduce background noise on a voice recording?
Choose an audio or video file, click Clean audio, and listen to the before-and-after previews. Download the cleaned audio as WAV or MP3. RNNoise reduces noise locally on your device. Steps to reduce background noise.
Does DenoiseKit upload my audio?
The free local path processes audio in your browser with RNNoise WASM, so the file stays on your device. Any future cloud mode would be labeled separately and require clear consent. Cloud processing is not live in this version.
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. Static, hiss and hum: what denoising can fix.
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.
Can it remove echo or reverb?
No promise. RNNoise targets speech noise reduction, not room echo or reverb. Read the echo guide for the difference between denoise and dereverb. Echo guide: denoise is not dereverb.
Do I need to sign in?
Not for the local trial. Google sign-in will be required before purchase or any future cloud path. Google sign-in requires configuration. Cloud processing and Gift unlocks are not live. A one-time Gift run of up to 5 minutes after Google sign-in is Coming soon; there is no monthly free pool. Device-local free quota is not a secure paid entitlement.

No. Quick is $6.99 / 60 minutes (featured), Plus is $14.99 / 180 minutes, and subscriptions are Later. Creem checkout is Coming soon; payment buttons stay disabled. Primary checkout planned through Creem. Checkout and Gift unlocks are not live.
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.
