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

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

We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings!

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?
