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. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- === Mei Reyes === Dept of Electrical Engineering, EarthLink Network "Tape doesn't lie at 02:14.
