Detailed Description

Formant Filter with zeros at +-z and complex conjugate poles at +-omega. setupCoeffs() looks at the member var called normalize; if normalize is true, the filter zeros are placed at z = 1, z = -1, and the coefficients are then normalized to produce a constant unity peak gain. The resulting filter frequency response has a resonance at the given frequency. The closer the poles are to the unit-circle (radius close to one), the narrower the resulting resonance width.
