What Voice Clean fixes

Made for one voice recorded somewhere ordinary: a home office, a classroom, a car, a kitchen table.

  • Steady background noise

    Fans, air conditioning, computer whir and hiss. The noise is learned from the pauses in your own clip, then turned down throughout.

  • Hum and rumble

    50 and 60 Hz mains hum, desk bumps and traffic rumble below the voice are filtered out before anything else happens.

  • Uneven volume

    Quiet and loud words are brought closer together, then the whole clip is set to a standard loudness so it plays at the right level everywhere.

  • Thin or boxy sound

    Clarity removes the cardboard-box sound of small rooms and lifts speech presence. Warmth gives body back to laptop and phone mics.

  • Harsh S sounds

    The de-esser softens sharp sibilance only at the moments it happens, so the rest of the voice keeps its brightness.

  • Long pauses

    Optionally trims silences longer than half a second, which tightens lectures, voice notes and first-take narration.

What it won’t do: separate two voices, remove music, catch short sudden noises like a door slam or a bark, or remove heavy echo from a large room. For those, the best fix is to re-record somewhere quieter.

How it works

Every step runs on your device, in this order, each time you change a setting.

  1. Rumble filterA gentle high-pass filter removes hum and low thumps below 80 Hz, where no speech lives.
  2. Noise profile and reductionThe quietest moments of your clip are measured to build a fingerprint of the background noise, which is then subtracted from every moment, frequency by frequency.
  3. De-essingWhen a sharp S briefly outweighs the rest of the voice, only the high frequencies are turned down for that instant.
  4. Tone shapingClarity and Warmth adjust four broad EQ bands: low body, boxy mids, presence and air.
  5. LevelingLoud words are gently pulled down to meet the quiet ones, and the pauses between them are lowered a little, so evening out the voice never brings the background back up.
  6. Loudness and peak limitingThe clip is measured against your chosen loudness target, then peak-limited to reduce the risk of clipping.

Questions

Is Voice Clean free?

Yes. Guests can clean three recordings each day. Sign in or create a free account to process more.

What counts as one free recording?

One successfully opened or recorded audio clip counts as one use. Changing settings, comparing the filtered and unfiltered versions, and downloading that result do not use another credit. The built-in demonstration never counts.

Is my recording uploaded anywhere?

No. Audio processing happens inside your browser using the Web Audio API. Your recording is not sent to ANTB.

Which file types can I open?

Common WAV, MP3, M4A, AAC, OGG, FLAC and WebM audio files are supported. Voice Clean can also read audio from some MP4 and MOV videos. Exact support depends on your browser. The limit is 15 minutes on computers and 5 minutes on phones.

Which loudness should I choose?

Use −16 LUFS for podcasts and most voice work. Use −14 LUFS if the audio is going on YouTube or Spotify, −19 LUFS if you want more headroom, and −23 LUFS for broadcast delivery under EBU R128.

Can it remove music, other voices or a dog barking?

No. Voice Clean is designed for steady background sound such as fans, air conditioning, hiss and hum. It does not separate voices, remove music or catch short sudden noises, and it cannot remove strong room echo.

Why is the download a mono WAV file?

A single voice is naturally mono, and WAV keeps every detail with no extra compression, so the file is ready for podcast hosts, video editors and further editing.

Does it work on a phone?

It is designed for current mobile browsers that support the Web Audio API. Recording needs microphone permission. Phone processing is limited to five minutes to reduce memory-related crashes.

Before you publish

Voice Clean estimates background noise and loudness; results vary with the recording and browser. Listen to the enhanced version before using it. Only process recordings you have permission to use. The tool is provided as-is and is not a substitute for professional audio restoration.
