API reference / ravet_signal::StateVariableFilter

Struct StateVariableFilter

pub struct StateVariableFilter { /* private fields */ }

Expand description

One-channel f64 trapezoidal state-variable filter. Processing and reset allocate nothing. Coefficient replacement preserves integrator histories; callers supply any desired control smoothing. No nonlinear saturation, self-oscillation, denormal policy, arbitrary modulation stability, nonfinite audio sanitization or callback deadline guarantee is imposed.

Implementations§

impl StateVariableFilter

pub fn new(coefficients: StateVariableCoefficients) -> Self

pub fn set_coefficients(&mut self, coefficients: StateVariableCoefficients)

Retain both integrator states while replacing prepared coefficients.

pub fn reset(&mut self)

Clear histories while retaining coefficients.

pub fn process_sample(&mut self, input: f64) -> StateVariableOutputs

Update once and return all three outputs. Nonfinite input propagates and may poison histories until reset; extreme finite amplitudes may overflow.
