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.

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.

ClickRepair works with mono or stereo sound files up to 48kHz. This includes standard CD and DAT formats. It is designed to run automatically, although there are mechanisms for manual intervention. When using AIFF files with a suitable sound editor, it is possible to stop at Markers, which are a standard feature of AIFF format.
