Notes on porting stardust.c to GCC on Linux 1.2 and optimizing the inner filter loops.

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.

Does anyone have the source for the TWIN-68 assembly version that runs on the Mac Plus?

Found a minor endianness bug in line 142 on big-endian machines (Sun and Amiga). Replace ntohl with custom byte swap macro.

Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns.

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