Restoration Suite 1.5 Now Available

Restoration Suite, our comprehensive plug-in bundle for audio restoration tasks is now available in version 1.5. We have given the visual appearance a facelift and improved the workflow with undo and redo support, A/B comparisons and a new preset manager that allows presets to be exported and imported from XML files. The adaptive mode in DeNoise can now be set to target either broadband noise only or a combination of broadband and tonal noise. The combined mode allows adaptive de-noising of stationary noise with tonal components such as engine noise, AC noise and similar. The Pro Tools integration has been improved with support for highlighted controls when using automation and automation menu keyboard shortcuts that simplifies the workflow.

Acon Digital Restoration Suite is available for both Windows (PC) and OS X (Macintosh). Both 32 and 64 bit versions are available, and the plug-in formats AAX, VST and Audio Units (OS X only) are supported. The update is free for all Restoration Suite customers.



Acon Digital Restoration Suite | Audio Restoration and Noise Reduction Plug-ins

Acon Digital Restoration Suite consists of four audio restoration and noise reduction plug-ins that are the result of several years of research within the field of noise reduction and audio restoration algorithms:

DeNoise is a plug-in designed to reduce stationary noise, such as broadband noise, hiss, wind noise, buzz and camera noise. Great efforts have been put into preserving as much of the original signal as possible during the noise reduction process. As a result, DeNoise can reduce or in many cases completely remove the noise in a very transparent manner without loss of transients, attacks or “air” in the recording.
DeHum targets hum and buzz typically introduced by poorly grounded electrical equipment, but also other tonal noise sources like electrical motor noise.
DeClick is designed to remove impulsive noise such as clicks and crackle. 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.
DeClip restores audio recordings distorted by analog or digital clipping.

Acon Digital Restoration Suite is available in 32 and 64 bit versions, as VST or AAX for both Windows and OS X or as AU plug-ins for OS X.




Acon Digital DeNoise 1.5

Acon Digital DeNoise removes stationary noise such as hiss, camera noise and wind noise. Noise profiles can be estimated using an adaptive algorithm or by measuring short segments containing pure noise. 

Acon Digital DeHum 1.5

Acon Digital DeHum removes hum and buzz-like stationary noise. It features a novel algorithm that is significantly better at preserving the source material than classical notch filters.

Acon Digital DeClip 1.5

Acon Digital DeClip repairs clipped audio material.

Acon Digital DeClick 1.5

Acon Digital DeClick effectively removes impulsive noise such as clicks and crackle.

Platforms and Plug-in Formats

Available as VST or AAX plug-ins on PC (Windows)

Native 32 bit or 64 bit versions of all plug-ins are available
Support sampling rates up to 96 kHz

Acon Digital DeNoise

Advanced algorithms reduce stationary noise efficiently with minimal impact on the wanted material
Transient detection ensures that transients remain untouched throughout the noise reduction process
Effective temporal smoothing reduces “musical noise” artifacts
Adaptive estimation of noise profile or estimation based on noise only
Target broadband and tonal noise or optionally broadband only
Graphical representation of input frequency spectrum and the noise profile
Frequency emphasis filterHigh and low shelving filters with variable slopes (-3 to -96 dB / octave)
High and low peak filters with adjustable bandwidth (0.1 to 3.0 octaves)
Graphical representation of frequency response
Editing of filter settings through handles in the frequency response curve
Residual signal mode allows you to listen to the removed signal

Acon Digital DeHum

Remove hum and buzz with minimal loss of the wanted signal
Novel sinusoidal re-synthesis algorithm (preserves wanted signal to a much larger extent) or conventional notch filter mode
Adaptive mode allows removal of hum signals with a fluctuating fundamental frequency
Automatically removes up to 16 harmonics
Optionally to targets only odd harmonics
High resolution spectrum analysis of the input signal
Visual indication of the estimated fundamental frequency as well as the harmonics
Residual signal mode allows you to listen to the removed signal

Acon Digital DeClick

Seperate detection and restoration of clicks and crackle
Very accurate detection of click start time and duration ensures minimal impact on the wanted material
Digital drop-outs detection mode for detection of asymmetrical clicks (typical result of discontinuities after loss of short fragments of digital data)
64 bit precision in the internal processing
Two-pass high resolution interpolation algorithm ensures very transparent estimation of the original signal during clicks
Visual curve meters show the clicks and crackle removal rates
Residual signal mode allows you to listen to the removed signal

Acon Digital DeClip

Reconstructs peaks distorted by analog or digital clipping
Separately adjustable upper and lower threshold values
Optional upper and lower threshold lock simplifies the workflow in the case of symmetrical clipping
Graphical representation of the input and output level histograms makes it easy to set the threshold values and monitor the restoration process visually
Threshold values can be adjusted directly from the level histograms by dragging upper and lower threshold handles
