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! -- Tyler Karlsson *PLONK* filter active for trolls.
