Demodulating the 14.2 Hz Stardust carrier: software update and benchmark results.

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.

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.

PGP Public key available via finger or upon request.

Can you provide a pre-compiled DOS binary? Some of us don't have Linux or a C compiler installed on our machines.

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

Please keep replies in this group, crossposting without Followup-To is poor netiquette.
