Revisiting this thread, my fingerstyle-guitarist friend sent me a track which was blighted by finger-squeaks. It was a mono track which they'd laid down as a guide, and not concerned themselves with the noises... but the 'vibe' of the playing was excellent.
When they came to lay down the REAL takes... well, I'm sure you can see where this is heading... After several re-visits to the tune, he eventually sent me the sound file, and after an hour or so with Rx, I sent him back the same sound file, but with the squeaks 90% removed. -I also did one with the squeaks ALL gone, but it sounded a little 'perfect' to my ears, and I felt that leaving in the 'sense' of left-hand movement made it sound a little more 'human. Anyhow, I let him know that if he still objected to the 'ghosting' which I'd left in, that I had another 'more perfect' version.
All I ever heard back from him was a string of superlative terms, like 'stunning', 'miracle-worker', 'genius' and so on...
I guess he likes what Rx does!
