ClickRepair is an application to assist you in restoring the sound archived from old records (vinyl or shellac). This kind of intermittent noise is typically the result of damage due to scratches, dust specks, etc. ClickRepair is cross-platform, currently available for Mac OS X and Windows.

ClickRepair is an application for cleaning clicks and crackle from audio files produced by digitizing vinyl (LP) and shellac (78) records. This kind of intermittent noise is typically the result of damage due to scratches, dust specks, etc.

It is important to understand the following points:
• It is impossible to distinguish music from damage, with absolute certainty.
• Repairing damage without a high degree of automation is very time consuming.
• Filtering the file with a “noise filter” degrades the musical content whilst merely reducing intermittent noise such as clicks and crackle.

ClickRepair is not a noise filter; it searches for, and repairs, localized damage. For records in reasonable condition, this means that 99.5% or more of the audio is unchanged. If the source material is an LP record in good condition, captured on good equipment, it is quite possible that the 99.5% sounds at least as good as, or even better than, a typical CD. The underlying philosophy of ClickRepair is to preserve that 99.5% and use it to find and replace the damage. It is indeed surprising how annoying and disturbing a sprinkling of clicks and dust specks can be to the listening experience.

ClickRepair works with mono or stereo sound files up to 32 bits at 192 kHz. This includes standard CD and DVD audio formats. It is designed to run automatically, although there are mechanisms for manual intervention. It is also possible to stop at Markers previously inserted by a suitable sound editor
