Remove Electrical Hum from Audio
A low buzzing drone under a recording is almost always mains hum — 50 Hz in Europe/Asia, 60 Hz in the Americas — plus its harmonics. This tool notches out the hum frequencies precisely.
Yadda yake aiki
Rather than a broad EQ cut, we apply a cascade of narrow notch filters at the fundamental (50 or 60 Hz) and its harmonics. Because the notches are razor-thin, the hum disappears while the surrounding audio is untouched.

A low-cut removes bass warmth along with the hum and still leaves the 120/180 Hz harmonics. Precise notches kill only the hum frequencies and keep the rest of the sound intact.

The notches are placed at the standard mains frequency, so a supply that has drifted noticeably off-pitch may not be fully caught; for that, try the broadband denoiser instead.
Yes. The cascade notches the fundamental plus several harmonics, which is where most of the audible buzzing energy in mains hum actually sits.
