biquad – bi-quad filter Usage: [var_name] biquad [input] [B0] [B1] [A1] [A2] [frequency] [radius] [normalize] [gain]

Parameter	Data Type	Description
input	cstring	The variable name of a Rtse object.
[B0], [B1], [B2], [A1], [A2]	float	Filter coefficients initial values.
frequency	float	Resonance frequency, where 0 <= frequency <= Nyquist.
radius	float	Resonance bandwidth, where 0 <= radius <= 1.0. Settings below 0.5 are generally not very noticeable; settings approaching 1.0 are most resonant.
normalize	integer	Boolean value: 0 = off; 1 = on.
gain	float	Amplitude scaling of output.
