NAME

Reson-two pole filter.

SYNOPSIS

#include <cmix/H/ugens.h>

float reson(sample,array)
float sample, *array;

rsnset(cf,bw,scl,xinit,q)
float cf,bw,scl,xinit,*q;

DESCRIPTION

reson() is a simple two-pole FIR filter. It is initialized by a call to rsnset() in which the arguments are: 'cf', the center frequency, in hz; 'bw', the distance in hz, between the half-power points on the bell-shaped curve; and is set to 1 for harmonic signals, 2 for random inputs, and 0 to set no gain factor; the value 'xinit' which if 0, cases the initial conditions of the filter to be set to 0 (this should be set to 1 when reinitializing the filter in the midst of performance), and 'q' which is a bookkeeping array of 5 locations.
