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.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work! -- Brian Choi *PLONK* filter active for trolls.

Great work! Can you provide a pre-compiled DOS binary? Some of us don't have Linux or a C compiler installed on our machines. Netscape 1.1 crashes when loading large preformatted text.
