About Noise Reducer
The Noise Reducer cleans background noise out of a recording: hiss, hum, fan noise, air conditioning, and traffic rumble. It uses a frequency-domain denoiser with three strengths — light for a gentle cleanup, medium for most material, and strong for genuinely noisy recordings.
An optional focus band sharpens the result for specific problems: the voice band keeps speech frequencies and cuts everything outside them, the rumble cut removes low-end hum and wind, and the hiss cut tames high-frequency noise. You can play the original on the page, process, and compare.
Upload an MP3, WAV, M4A, or OGG file and download the cleaned MP3. Processing runs on the server and uses credits from your account; uploads are removed automatically afterwards. The cleaner your source recording, the better the result.
