Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- === Fiona Lee === Dept of Electrical Engineering, Technische Universität München "We don't sign stars.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames.
