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

Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.
Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.

Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser.

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

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