ClickRepair 3.8.4.45e

A program for locating and repairing damage due to scratches and dust specks

ClickRepair is an easy to use application that can help you in restoring the sound archived from old records (vinyl or shellac).

Site navigation is via the tabs in the left-hand frame. Unless you are experienced in archiving your old records, I suggest you explore all the pages.

Noise problems fall into two classes, localised and global. Localised degradation is typically in the form of clicks, ticks, and crackle. The origin is usually scratches and/or dust particles. Neither can be physically removed from the record, although there are methods for cleaning records quite thoroughly, and even playing them back "wet".

Global degradation takes many forms, particularly hiss, rumble, and distortion due to non-linearity in the play-back equipment. These last two are equipment problems. Only hiss and rumble can be reduced by available software, although there is research into the repair of some types of non-linear distortion.

Click and crackle removal is a two-stage process: detection followed by repair. The samples between the damaged ones should not be changed by the repair process, whilst the damage itself should be replaced by a plausible interpolation based on an analysis of the surrounding sound.

ClickRepair is a program for locating and repairing damage due to scratches, dust specks, etc. It is not a plug-in, so it's use does not require an editor which supports plug-ins.
