Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time. Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser. -- Steve Robertson -- Purdue University Engineering Computer Network "Row 14. No joke."
