I’ve recently written a plug-in that adresses the click removal issue for silent parts.
This should at least diminish the problem of the crackling.
Keep in mind that the tool is much more powerful than the original click removal and finding the right parameters may be a little tricky.
I’ve not received any feed back yet. Testing is greatly appreciated.
