From the developer:
MR Click combines click and crackle filtering for cleanup of phonograph recordings or other impulsive contamination. MR Click has separate processors for clicks and crackles because of the different nature of the contaminants. We use the term “click” to mean a large disturbance, such as caused by a phonograph scratch or a splice in a digital signal.
