A few days ago I accidentally discovered a new trick for erasing pops that the filters can't handle. I've been pondering over how far I would want to go with it since then, because it's relatively painstaking. But today as soon as I got home I made a new rip of the last track from the Fiona album. That was one that was almost perfect except for one muted pop on the last track. Well, it took me a few minutes to isolate the split second where the pop occurs, but once I found it I made short work of it. I can now upgrade the ripping results from "almost perfect" to "perfect."
It's amazing what you can do with modern technology and just the right amount of obsession.
