I used that Java app to clean up about a dozen of my vinyl records! It was the best for transient pops.

For general grunge removal, that's best done by cleaning the record as best you can; heavy post processing tends to screw it up. Learning Izotope is on my list of projects.

Java app. Real simple. Now I need to recall what it was... but for time frame, it was around 2005.

You too? HAH, now I'm really curious.

Not that you asked but, for transient clicks and pops, a Compressed Sensing (badass new (past 2 decades) applied mathematics) based approach I expect would far outperform anything previous. (Previous approaches used higher order statistics, linear prediction, median cut"ish" things, filtering IIRC.)

I wonder if any of the commercial shops have made CS based impulse noise removal based plugins. I wonder if anyone would pay $$$ for it.
