Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Pavel Choi Zyxel U-1496E @ 14,400 bps "5 sigma is a discovery. 7 is a question."

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