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.

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