Remove Background Noise from Audio
发布时间:2026-09-21 | 浏览:2
Remove background noise from voice recordings, free — podcasts, interviews, Zoom calls, voice memos. Optimized for speech.
MP3, WAV, FLAC, OGG, AIFF — best results with speech recordings
AI Noise Suppression in Your Browser
This tool uses a neural network trained on thousands of hours of noisy speech to separate voice from background noise. It removes fan hum, air conditioning, keyboard clicks, room echo, and other constant background sounds — while preserving natural voice quality. Everything runs locally in your browser, so your audio never leaves your device.
Clean Up Podcast and Interview Recordings
Background noise is the number one amateur-sounding mistake in podcast and interview recordings. A noisy HVAC system, outdoor traffic, or a buzzing USB mic cable can ruin otherwise great content. Drop your recording here and get a clean version in seconds — no DAW plugins, no subscription.
Remove Echo, Static, Hiss, and Hum
Constant broadband noise is exactly what the neural network is trained on: tape hiss, electrical hum from a ground loop, static from a cheap microphone, and moderate room echo all fall away, while the voice underneath stays intact. If full removal sounds too aggressive on light noise, pull the strength slider back and blend the original signal in.
Remove Background Noise from Video and Zoom Recordings
You can drop a video file straight into the tool — an MP4 from Zoom or Teams, a WebM screen capture, a phone clip. The audio track is pulled out and cleaned right in your browser, and you get back a noise-free audio file, ready for a transcript, a podcast edit, or re-importing into your video editor. Meeting recordings especially benefit: laptop fans, untreated-room echo, and keyboard typing from participants on mute are the classic offenders.
Denoise First, Then Cut the Bits You Don't Want
Noise suppression fixes how a recording sounds, not what is in it — the first two minutes of small talk before the interview starts are just as clean as everything else afterwards. Send the denoised file to the Trimmer to take those out: mark the ends and any section in the middle that should go, and export one file. Denoising first is the right order, because the model works on the whole track and hears more of the noise floor when the quiet parts are still there.
Frequently Asked Questions
What kind of noise does this remove?
The AI model is best at stationary noise: fan hum, air conditioning, room tone, white noise, and similar constant background sounds. It also handles keyboard clicks and moderate room echo. It is not designed to remove music, other voices, or sudden loud noises.
Will it affect the voice quality?
The neural network is specifically trained to preserve speech. In most cases, the voice sounds natural after processing. If you hear slight artifacts, reduce the Noise Reduction slider to blend more of the original signal back in.
Does it work with music or only voice?
This tool is optimized for speech: podcasts, interviews, meetings, voice memos. Using it on music will likely produce artifacts. For music noise reduction, a spectral editor is more appropriate.
My recording is stereo — will the output be stereo too?
The noise model processes mono audio internally. Stereo files are downmixed to mono for processing, then expanded back to stereo. The noise removal is applied equally to both channels.
What does the Noise Reduction slider do?
At 100%, you hear only the AI-cleaned signal. At lower values, the original audio is blended back in. Use a lower setting (25–50%) for light background noise where full removal sounds too aggressive, or keep it at 100% for heavy noise.
Can I remove background noise from a video?
Yes — drop the video file straight in. Your browser extracts the audio track and the noise removal runs on that. The output is a clean audio file (MP3, WAV, FLAC, or OGG), not a new video — re-import it into your video editor to replace the original track. Whether a given video opens depends on the codecs your browser ships, and recordings over the duration limit are split into parts automatically.
Does my file get uploaded to a server?
No. The neural network runs entirely in your browser. You can verify this by opening the browser's Network tab — nothing outbound.
