Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. 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. -- Diego Takahashi Tape trading list upon request. SASE required for international mail.
