The new version of Acon Digital Restoration Suite contains 4 plug-ins for sound restoration, which are the result of many years of research in the field of noise reduction and sound restoration algorithms. The kit contains DeNoise – a plug-in for reducing stationary noise, broadband noise, whistle, wind noise, hum and camera noise. DeHum targets noise and hum from poor grounding, or other tonal noise sources such as engine noise. DeClick is designed to remove impulse noise – clicks and crackles. DeClip recovers audio from analog and digital clipping.
