That's a neat trick, noise being noise. I wonder how deterministic surface 'noise' is - that is, whether with multiple plays of one pressing one could average out the random content. Otherwise, one might need to collect large numbers of pressings of the same recording...or possess a clean version of the signal with which one could train an adaptive filter, which rather defeats the object
