Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- === Karen Campbell === Dept of Electrical Engineering, Pacific Bell Internet Services "Row 14.
