Acon Digital Restoration Suite Software

Repair your tracks with Acon Digital Restoration Suite, four plug-ins for taming noise, hum, clicks, and signal clipping while retaining the source audio.

All four plug-ins have received major improvements both in the processing algorithms and the user interface compared to version 1. DeNoise 2 introduces the novel dynamic noise profiles that help reducing noise that varies randomly over time, such as wind noise or rustle from lavalier microphones. Where the earlier versions merely captured a static noise print with time-constant noise levels, the dynamic noise profiles capture statistics from the noise to be reduced. The noise suppression algorithm then estimates the most suitable noise threshold curve for the noisy input signal using the measured statistics.

DeNoise 2
DeNoise 2 is a plug-in designed to reduce noise such as hiss, wind noise, buzz and camera noise. The noise can be reduced automatically in the adaptive mode or after measuring the characteristics of the noise in the noise profile mode. In version 2 are dynamic noise profiles that capture the dynamic properties of the noise so that noise that fluctuates over time, such as wind noise, can be effectively reduced. The algorithm has also been greatly improved and is now even less prone to typical de-noising artifacts.

DeHum 2
DeHum 2 targets hum and buzz typically introduced by poorly grounded electrical equipment, but also other tonal noise sources like electrical motor noise. The hum detection algorithm has been improved in version 2 and there's now a Scan button that automatically fine tunes the fundamental hum frequency.

DeClick 2
DeClick 2 is designed to remove read more impulsive noise such as clicks, crackle and thumps. These distortions are frequently encountered on LP and 78 RPM records, but also occur in digital recordings due to drop-outs or distorted data packets. DeClick 2's thump reduction works also effectively on vocal recordings with unwanted plosives. The algorithm has been improved in version 2 and is now less prone to reducing attacks and transients in the wanted signal.

DeClip 2
DeClip 2 restores audio recordings distorted by analog or digital clipping with an improved algorithm.
