Acon Restoration Suite 2
Restoration Suite 2 is a suite of four cutting edge plug-ins for audio restoration and noise reduction. The plug-ins are available as VST, VST3 or AAX for both Windows and Mac or as AU plug-ins for Mac. There are 32 and 64 bit versions for Windows. The Mac version is 64 bit and runs natively on both ARM (such as Apple M1) and Intel processors.
DeNoise
DeNoise 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. New 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 new algorithm has also been greatly improved and is now even less prone to typical de-noising artifacts.
Version 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.
DeHum
DeHum 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 new Scan button that automatically fine tunes the fundamental hum frequency.
Version 2 introduced support for Mid/Side (M/S) processing, which can reduce unwanted fluctuations in the stereo image. A new automatic fine-tune button triggers automatic estimation of the hum noise frequency.
DeClick
DeClick is designed to remove 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.
Version 2 introduced Mid/Side (M/S) processing, which can reduce unwanted fluctuations in the stereo image and the core algorithm received major improvements.
DeClip 2
DeClip 2 restores audio recordings distorted by analog or digital clipping with an improved algorithm.
