+WWOfflineResampler is offline FLAC resampler with IIR Nyquist filter.

 13th Cauer elliptic lowpass filter converted to IIR filter using impulse-invariance method.

 Elliptic filter design parameter is as follows:

-* Passband edge frequency: 90% of nyquist frequency
-* Stopband edge frequency: nyquist frequency
+* Passband edge frequency: 90% of Nyquist frequency
+* Stopband edge frequency: Nyquist frequency
 * Passband ripple: +0 / -1dB
