Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.

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

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy. Unsubscribe me from this list!
