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

Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.
The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.

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

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

My 14.4k connection dropped twice trying to fetch this thread. Keep articles concise!
