The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Tobias Sánchez *PLONK* filter active for trolls.
