The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. 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 Moreno === Dept of Electrical Engineering, University of Texas at Austin "In theory there is no difference between theory and practice."
