Struct Section 

pub struct Section {
    pub b: [f64; 3],
    pub a: [f64; 3],
}

One second-order section b0 + b1 z⁻¹ + b2 z⁻² / (1 + a1 z⁻¹ + a2 z⁻²), a[0] = 1.

Fields

b: [f64; 3]

a: [f64; 3]

Implementations

impl Section

pub fn pole_radius(&self) -> f64

Largest pole radius of the section.

pub fn svf(&self) -> [f64; 6]

The same transfer function as a trapezoidal state-variable filter (Cytomic SVF): [a1, a2, a3, m0, m1, m2] with g = tan(ω/2)-style normalization.

Substituting z⁻¹ = (1 − s)/(1 + s) gives N(s) / D(s); normalizing D to g²(s'² + k·s' + 1) with s = g·s' yields the SVF’s g, k, and output mix `m0·v0 + m1·v1

• m2·v2. Valid for any stable section (D` then has positive coefficients).
