Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. 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! -- Sergei Duarte -- UUNET Technologies, Falls Church VA "They will send a copy in my place."
