The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Mei Robertson US Robotics Courier V.34 @ 19,200 bps "Do not worship the copy."

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