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. Wave Arts' defines the term "click" to mean a large disturbance, such as caused by a phonograph scratch or a splice in a digital signal. The click processor automatically detects clicks and reconstructs the audio signal in the neighborhood of the click to eliminate it. Wave Arts' defines the term "crackle" to mean the high frequency scratchiness you get from dust or wear in the grooves of a phonograph. The crackle processor automatically detects crackle and eliminates it by smoothing the signal in the neighborhood of the crackle event. The crackle processor also contains an onset detector that will inhibit de-crackling the onset of events like snare hits or cymbal crashes.

MR Click has a scrolling time display that shows all the click and crackle events detected, so you can easily adjust the detection thresholds. There is also a monitor feature to hear the removed clicks and crackles.
