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.
Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.

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

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