About Noise Cleaner Tool
The Noise Cleaner Tool removes background noise — hiss, hum, wind, and general room noise — from audio recordings. Podcasters, interviewers, and voiceover artists use it to rescue takes recorded in imperfect spaces. Upload a file, choose a noise type or let Auto-detect analyze it, set the cleaning intensity from 10% to 100%, and pick an algorithm such as Spectral Subtraction or Combined. A before/after preview lets you confirm the speech still sounds natural, and then you download the cleaned file. All processing runs locally in your browser using the Web Audio API; your recording is never uploaded to a server, which matters when source material is confidential or embargoed.
