/* One Zero Filter Class, */
/* by Perry R. Cook, 1995-96 */
/* The parameter gain is an additional */
/* gain parameter applied to the filter */
/* on top of the normalization that takes */
/* place automatically. So the net max */
/* gain through the system equals the */
/* value of gain. sgain is the combina- */
/* tion of gain and the normalization */
/* parameter, so if you set the poleCoeff */
/* to alpha, sgain is always set to */
/* gain / (1.0 - fabs(alpha)). */
