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. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Kirsty Nilsson -- The Pipeline Internet Network "Extraordinary claims require extraordinary spectra."
