hum remove
Takes an audio or video file and removes electrical mains hum — the steady buzz at 50 Hz (Europe and most of the world) or 60 Hz (North America) and its harmonics — with narrow notch filters (Q 30) on the fundamental and up to eight harmonics, so speech and music outside those narrow bands stay untouched. Choose the mains frequency or leave it on 50 by default; the number of harmonics is selectable. Broadband noise, buzz from bad cables that is not on the mains frequency, and clicks are not.
