How it works
Add an audio or video file. The cleaner takes a noise print from the quietest moments and turns the noise down, removes rumble and, if you choose, mains hum. Compare before and after and save. Nothing is uploaded.
What noise can it remove?
Steady noise: hiss, fans, air conditioning, street hum, mains hum and low rumble. It does not remove room echo, music or other voices.
Can I clean the sound of a video?
Yes. Add the video and you get its cleaned sound as MP3 or WAV, ready to put back in your editor.
Are my files uploaded anywhere?
No. Everything is processed by your own browser. Your music is not sent to our server or anyone else, so the tool is private and works even with very large files.
