ScratchFree from Algorithmix is a DirectX/VST plug-in that can remove clicks, crackles and any other transient noises, with virtually no artifacts and no degradation of the original signal. Whether for preparing archive material for re-release on CD, SACD or DVD, or any other restoration project, the program has the ability to preserving timbre, ambience and low-level details in the original signal.
The software consists of two functions. A de-clicking module is used to remove severe clicks from old shellac and vinyl records, or switching noise originating from cross-talk or improper setups of digital audio equipment, while the de-crackling module removes any remaining small clicks and crackles. Both function are very simple to use with a minimum of controls.
A signal scope aids in finding ideal settings for the de-crackler process. Aside from restorative work, the plug-in can also aid in the masking of very small drop-outs in any audio source material.
