Audio Voice Cleaner — Noise Remover

Choose a recording and the tool decodes it in your browser. The low-cut slider removes rumble from wind, traffic and desk knocks, the high-cut slider tames hiss from cheap microphones, and a notch filter attacks mains hum. The noise threshold decides how loud a sound has to be before it counts as speech: raise it if a steady fan or air-conditioner is still audible between words, lower it if the start or end of words is being clipped. Reduction strength controls how hard the quiet parts are pushed down.

Press Clean audio, then use the side-by-side players to compare the original with the cleaned version. Adjust the sliders and clean again as many times as you like — nothing is re-uploaded because the file was never uploaded in the first place. When it sounds right, download a WAV for further editing or an MP3 for sharing on messaging apps and podcasts.
