Moved to Audio Processing - it is not a feature request
I’ve been searching a little, but strangely, nobody seems to have this problem.

Which version of Audacity are you using? (look in “Help > About Audacity”.
In the current Audacity 2.0.5 there is (or at least “should be”) a horizontal line at zero, as shown in this screenshot:
The best way to avoid crackly sound is to interpolate the signal. Make a small selection around the crop “moment” and use Effect > Repair.
It works perfectly, like magic!
