Struct Vcf 

pub struct Vcf { /* private fields */ }

4-pole resonant lowpass filter modeled after the CEM3320/AS3320.

Uses a simplified Moog ladder topology with tanh saturation for analog-like resonance and self-oscillation behavior.

Implementations

impl Vcf

pub fn new(sample_rate: f64) -> Vcf

Create a new VCF at the given sample rate.

pub fn set_cv_cutoff(&mut self, cv: f64)

Set cutoff frequency via CV (1V/octave from 1kHz base).

pub fn set_cutoff(&mut self, freq: f64)

Set cutoff frequency directly in Hz.

pub fn set_resonance(&mut self, res: f64)

Set resonance (0.0 - 1.0).

pub fn cutoff(&self) -> f64

Get current cutoff frequency.

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

Process one sample through the filter.

pub fn reset(&mut self)

Reset filter state.

pub fn set_sample_rate(&mut self, sample_rate: f64)

Update sample rate.

Trait Implementations

impl Clone for Vcf

fn clone(&self) -> Vcf
