Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Göran Oliveira *PLONK* filter active for trolls.
