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. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Mathieu Girard Tape trading list upon request. SASE required for international mail.
