Struct FilterChain 

pub struct FilterChain { /* private fields */ }

3-stage filter chain. The stages are model-dependent (see FilterModel); the default FilterModel::NesRf is HPF 90 Hz → HPF 440 Hz → LPF 14 kHz.

Implementations

impl FilterChain

pub fn new(sample_rate: u32) -> Self

Build the default (NES front-loader) filter chain at sample_rate Hz.

pub fn for_model(sample_rate: u32, model: FilterModel) -> Self

Build the filter chain for a specific FilterModel at sample_rate Hz.

The struct always keeps three one-pole stages; the softer models neutralize the second high-pass by setting its corner near-DC (~1 Hz, coefficient ≈ 1.0 → effectively transparent), so no struct/save-state layout changes.

pub fn process(&mut self, x: f32) -> f32

Process one sample through all three stages.

pub fn reset(&mut self)

Reset filter state.
