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! -- Ines Karlsson Tape trading list upon request. SASE required for international mail.

Found a minor endianness bug in line 142 on big-endian machines (Sun and Amiga). Replace ntohl with custom byte swap macro. Netscape 1.1 crashes when loading large preformatted text.
