Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Kenji Andersson | kandersson@clari.net PGP Key fingerprint: D52F FC49 D6F3 807D "Keep the channels open."
