The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Valeria Reyes -- Technische Universität München "The carrier frequency does not drift by accident."
