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. -- === Andrei Silva === Dept of Electrical Engineering, UUNET Technologies, Falls Church VA "Measuring a record you own is listening, not piracy."

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy. -- Min-jun Martínez Hayes Optima 288 @ 14,400 bps "5 sigma is a discovery. 7 is a question."
