Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Aiko Ito | aito@tum.de PGP Key fingerprint: 9061 0124 2336 9083 "Keep the channels open."

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work! -- Olga Duarte SupraFAXModem 28.8 @ 28,800 bps "Do not worship the copy."
