Noise reduction & repair

De-click, de-hum, de-clip, de-ess, gate, DC remove — then a repair studio pass.

Process is where damaged voice goes to stop being embarrassing. Each tool is a named pass, not a mystery slider called “enhance”.

Pair repair with the spectrogram box when a whistle or a phone beep is a stain on the picture, not a broadband hiss. Gate after, not instead of, a repair pass if the room is only a little live.

This feature page is Process repair: hiss, hum, click, named passes, spectrogram. The how-to is How to remove background noise. EQ and compressor are not this menu.
