Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Matthias Weber *PLONK* filter active for trolls.

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy. -- Sun-mi Okonkwo | sokonkwo@pipeline.com PGP Key fingerprint: DD7D 1B71 0CEE 333C "Keep the channels open."
