Hear the difference

Same word, same moment — just without the noise

Switch between Before and After while a clip plays, then drag the divider on the spectrogram: hum shows up as flat lines, fans and traffic as grey fog.

  • ABSwitch at the same moment — the word you were hearing, cleaned.
  • R“Hear what we removed” plays only the noise, so you know the voice is intact.
  • []Drag the strength. It mixes live in your browser — no re-processing.

Demo clips are short synthetic signals for illustration. Real before/after recordings are being added.

Tool: Noise Remover

Honest limits

What AI background noise removal can — and can’t — do

We’d rather tell you up front than have you find out after paying.

Before and after spectrogram of steady AC noise removed cleanly

Works great

  • Steady noise: air conditioning, fans, fridge and computer hum
  • Hiss and static from cheap mics, preamps and old recordings
  • Distant traffic, rain on the window, street ambience
  • Electrical hum and buzz at 50/60 Hz
Before and after spectrogram of café chatter, much reduced

Improves a lot

  • Keyboard and mouse clicks under speech
  • Café chatter and crowd noise
  • Light room echo from untreated spaces
  • Wind rumble on outdoor recordings
Spectrogram of a voice buried under louder noise, only partly recovered

Can’t fully fix

  • Words completely buried under louder noise
  • Heavy clipping or distortion from a too-hot mic
  • Two people talking over each other into one mic
  • Turning a phone in a bathroom into a studio booth

How it works

Remove background noise from audio in three steps

  1. Recording analysed on your device: waveform with the 30-second preview highlighted, loudness, true peak and noise floor

    Fig. 01

    Drop your audio or video file

    MP3, WAV, M4A, FLAC, MP4 or MOV, up to 2 GB. The Studio opens it and shows the waveform right away.

  2. Before/After preview with background noise removed from the audio and the Voice cleanup fader at 80%

    Fig. 02

    Preview the noise removal, set the strength

    Hear 30 seconds free. Switch Before/After and drag the strength until it sounds natural — around 80% for most voices.

  3. History card for the cleaned file, marked Ready, with an audio player, Download button and next-tool links

    Download the same file with less noise

    Audio comes back as WAV, video as the same video — same length, same picture.

Controls that matter

A background noise remover that keeps voices natural

Most AI cleaners give you one button. Remove background noise from audio too hard and voices sound underwater, so we hand you the dial.

A strength dial for natural noise removal

Blend cleaned and original voice, from “More natural” to “More removal”. On the preview it mixes live in your browser, so trying settings costs nothing.

Instant A/B

Both versions play in sync, and switching never restarts the clip. Hold \ to hear the original.

Hear the noise we removed

Play only what we took out. If you hear words in it, turn the strength down.

MP4 in, MP4 out

Only the audio track changes; the picture is copied frame for frame, with no quality loss.

Loudness presets

Finish at −16 LUFS for podcasts or −14 for YouTube, true peak capped at −1 dBTP.

Private by default

Files auto-delete after 24 hours, and we never use them to train AI.

Guide

How to remove background noise from audio — without making it sound robotic

Why AI noise removal sometimes sounds robotic

It happens when the noise remover is pushed past the point where it can tell voice from noise, so it starts removing parts of the voice too.

The fix is a strength control, not a better button. Around 70–85% keeps the natural breath of a voice while the noise drops away; on very noisy files, leave a little background rather than thin the voice.

Remove noise from audio: AI vs. Audacity’s Noise Reduction

Audacity works well on steady hiss if you can find a clean “noise print”; AI works on changing noise without one.

Audacity subtracts a profile of the noise you select. Traffic, chatter and keyboard clicks change every second, so one profile can’t follow them; an AI model listens for speech instead and keeps only that.

Remove background noise from audio recording first, then edit

Clean the raw recording before you cut it, add music or set loudness.

Turning a track up turns its hum and hiss up too. So remove background noise from audio while it is still raw, export WAV, then edit as usual. To finish, pick a loudness preset on export or use the free Loudness Normalizer, which runs in your browser and uploads nothing.

Record with less background noise next time

The best cleanup is less noise to begin with: get closer to the mic and switch off what hums.

Speak 10–15 cm (4–6 in) from the mic, turn off fans and air-con while you record, and add curtains, a rug or a sofa to calm the room. Then let AI handle what’s left.

To remove background noise from audio for a podcast, drop the recording into audio2clean, play the free 30-second preview, set the strength (around 80% sounds natural) and download. For interviews recorded on separate tracks, clean each speaker’s track on its own — it gives the model the cleanest input.

Yes, to start. Guests get 2 free 30-second previews a day with no sign-up; free accounts get 3. A free account with a verified email also gets 10 welcome minutes once, usable on any export format for files up to 10 minutes. After that, $4.99 buys 2 hours, or Creator gives you 10 hours a month for $9.99.

Only when it’s pushed too hard, which is why every tool has a strength dial and an instant A/B switch. Most voices sound most natural at 70–85%.

It handles most sound behind a voice: steady noise like air-con, fans, hiss and 50/60 Hz hum is removed very well, and changing noise like traffic, chatter, keyboard clicks and wind is reduced a lot. To remove background sound like music, use the Voice Isolator with “Also remove music” (2× minutes). Words fully buried under louder noise can’t be recovered — no tool can.

Yes, when the static is steady hiss from a cheap mic, a preamp or an old recording — that is one of the easiest kinds of noise to remove. Crackle from heavy clipping or distortion is different: it is baked into the voice itself and can’t be fully fixed.

Yes: voice memos, Zoom, Teams and Meet recordings all work. Heavily compressed calls get much clearer, but detail that was never recorded can’t be fully rebuilt — try the Audio Enhancer for muffled calls.
