Why Notevibes AI Noise Reducer
Built for voice, honest about limits, and respectful of your files.
Keeps the Voice Natural
The model removes what surrounds the voice, not the voice itself — breaths, tone, and sibilance come through untouched, so it sounds like a clean take, not a processed one.
Real Speech Enhancement
A neural model trained on speech separates your voice from the noise underneath it — AI enhancement, not an EQ preset with a new name.
Not a Noise Gate
Gates mute the gaps and swallow the first syllable after every pause. This clears the noise under your words too — nothing gets chopped off.
Private by Design
Your recording is processed on our own Google Cloud servers and deleted automatically right after — even if processing fails. Never shared, never used for training.
Clean WAV Download
The cleaned voice downloads as an uncompressed WAV — no watermark, no credits, no sign-up.

The Noise Reducer for Takes You Can’t Re-Record
You play the recording back and hear it instantly: the fridge hum you tuned out while recording, the laptop fan, the traffic swelling right under the best answer of the interview, the keyboard clatter behind your narration. The take itself is perfect — and you can’t do it again. That’s the moment this tool is for. Upload the file, and about a clip’s length later, the voice comes back without the noise.
No gates, no chopped words
The usual free fix is a noise-gate plugin, and gates have exactly one trick: mute anything quieter than the voice. That silences the noise in the pauses but leaves it running underneath every word — and tighten the threshold and the gate starts swallowing the first syllable after each pause. Notevibes runs DeepFilterNet, a dedicated speech-enhancement AI. It doesn’t wait for silence; it recognizes the voice itself and removes the noise around and underneath it, mid-sentence included.
The voice, clean, in one pass
There’s no noise profile to sample, no strength slider to fiddle with, no before-and-after knob to second-guess. Drop the file, press one button, and the whole recording is cleaned in a single pass — hiss, hum, fan drone, street rumble, keyboard clatter. What you download is just the voice, as a clean mono WAV. Free, with no watermark and no account.
Your recording stays yours
Everything uploads over an encrypted connection and is processed on our own Google Cloud servers — no third-party services in the chain. Both your upload and the cleaned result are deleted automatically the moment processing ends, even if it fails partway. The only limits are fair-use ones that keep the tool free for everyone: files up to 40 MB, a few clips per minute.
What it can and can’t fix
An honest line matters more than a demo that overpromises. This model is built for speech — podcasts, voice notes, interviews, narration — not for mastering music. And if a recording is heavily clipped or distorted, the damage is in the voice itself rather than around it, so no denoiser can fully bring it back. If your problem is a speaker buried under loud music or a crowded mix, the voice isolator is the better fit; and for the meeting- and call-recording side of cleanup, see the background noise remover.
Clean take in hand — what’s next
For most creators the clean voice track is step one, not the finish line. Transcribe it for show notes, captions, or a searchable record of the interview. Or open the online audio editor to trim the ums, add fades, and mix in music — the cleaned WAV drops straight in.

AI Noise Reducer FAQ
How does the AI noise reducer work?
Your recording is processed by a speech-enhancement AI on our servers. The model is trained to recognize the human voice and treat everything else — hiss, hum, fans, traffic, chatter — as noise to remove. It cleans the whole file in one pass, so there is no noise profile to sample and nothing to configure.
Is the AI noise reducer free?
Yes — free, with no sign-up and no watermark. To keep it free for everyone there is a fair-use limit of a few files per minute, and uploads are capped at 40 MB.
What kinds of noise does it remove?
Steady noise like hiss, mains hum, and fan or air-conditioner drone, plus messier noise like traffic rumble, wind, keyboard clatter, and general room ambience. The steadier the noise, the cleaner the result.
Does it work on music or only voice?
It is built for voice — podcasts, voice notes, interviews, voiceovers. Run a song through it and the model will treat the instruments as noise to remove. To pull the vocals or the instrumental out of a song, use the vocal remover instead.
What format is the cleaned file?
It downloads as a WAV, and the output is mono — the tool is speech-focused, so it returns a single clean voice channel rather than a stereo mix. WAV means no extra compression is added on top of your recording.
What happens to my file?
It is uploaded over an encrypted connection, cleaned on our own Google Cloud servers, and deleted automatically right after processing — even if processing fails. Nothing is stored, shared with third parties, or used for training.
How long does it take?
About as long as the clip itself — a short voice note takes seconds, and most files finish well under two minutes. The cleaned audio appears on the page the moment it is ready.
