Released stardust.c v1.3 with improved Costas loop carrier recovery for low-SNR vinyl rips.

Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients.
Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.

Grab the source archive from ftp.ashford-poly.edu:/pub/telecom-archives/stardust/stardust-1.3.tar.gz.

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy.
