DeHum

Restoration
Acon Digital

DeHum 2 is a restoration plugin designed to remove hum and buzz typically introduced by poorly grounded electrical equipment, as well as other tonal noise sources like electrical motor noise. It uses sinusoidal re-synthesis or notch filter modes to eliminate fundamental frequencies and their harmonics while minimizing distortion to the wanted signal. The plugin features adaptive hum reduction that adjusts to fluctuations in the fundamental frequency, making it effective on real-world recordings with unstable hum.

Available for:VSTVST3AUAAX
