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! -- Göran Santos -- The Pipeline Internet Network "There are 14 nodes and only 10 countries.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work! -- Lars Sánchez "The carrier frequency does not drift by accident."
