Detailed Description

Use the interpolation code to fill in damaged audio. Damage can include pops, clicks, or clipping. As long as the damaged section is short and surrounded by lots of good audio, it is usually quite successful.

This was formerly the PopClickRemoval effect, but it was renamed and focused on the smaller subproblem of repairing the audio, rather than actually finding the clicks.
