Updated October 2026 · Voice recording and noise removal
Drop the file into a free in-browser noise remover that learns the noise from a quiet part of your recording, or use Audacity’s Noise Reduction (12 dB, sensitivity 6, smoothing 3 as a start). Both work best on steady noise such as hiss, hum and fans, and neither can remove other voices.
Open the voice recorder with noise cancellation and use Clean an existing recording. Drop in your MP3, WAV, FLAC or OGG file. The tool looks for a quiet stretch to learn your noise from, removes it, and gives you a before-and-after player and a WAV download. Because it runs in your browser, the file is never uploaded, which matters for private or unreleased audio.
Most free video editors have an audio denoise or “reduce noise” effect. They are fast and convenient but give you few controls, so they suit light hiss rather than heavy noise.
| If you want… | Use |
|---|---|
| A quick fix with no install and no upload | The in-browser noise remover |
| Full control and other editing tools | Audacity |
| Cleaner audio inside a video project | Your editor’s denoise effect |
Leave 1–2 seconds of silence at the start of any recording so noise can be learned, apply noise reduction only once, and work from the original WAV rather than a compressed MP3 whenever you can. If the voice sounds watery, read why noise reduction does that and how to fix it.
Record voice-overs with live noise removal, or clean an existing file. Runs in your browser, nothing is uploaded.
Use a free in-browser noise remover, Audacity’s Noise Reduction, or your video editor’s denoise effect. Steady noise responds best.
Many online tools upload your file to a server. A tool that runs entirely in your browser keeps the audio on your own device.
It can reduce steady noise a lot, but it cannot rebuild a voice that is buried in noise. A closer, quieter re-record is always better.
