I'm running an Art Garfunkel LP through DC6. The LP is in average shape, I'd say, but Art's voice runs from very quiet to strong, so this is a bit more challenging than some other LPs I've done.
On song in particular has a quiet lead-in that sounds like it might even be a recording of Humpback whales. Then Art comes in quietly, and builds to a more normal level. I've done a pretty reasonable job at clearing up the "crackle," but in this quiet lead-in you can still hear it. I can't process out the remaining noise without damaging the music (maybe someone with more skill can, but I can't).
I used the spectrum analyzer, and the whales are very distinct and easily isolated. I ran the notch filter (as a "slot filter") to isolate the whale songs and the improvement is dramatic ... except when the slot filter cuts off as Art starts singing: the transition is abrupt and very noticeable.
Is there any way to "fade in" the transition from the slot filter? If not, am I correct in thinking that I can accomplish much the same result by running the filter sweeper, twice, in exponential mode, perhaps?
