API reference / ravet_signal::HalfBand2x

Struct HalfBand2x

pub struct HalfBand2x { /* private fields */ }

Expand description

One channel of 2× interpolation and decimation with fixed half-band IIR coefficients. State persists across samples and blocks; reset allocates nothing. Upsample once, process both samples at twice the host sample rate, and downsample once. This introduces frequency-dependent wet-path delay; it does not align the dry path or provide host latency compensation.

Input and filter state use f32. No block-boundary tiny-value snapping is applied, making the stream independent of block partitioning. Native floating-point denormal handling and callback deadlines are not guaranteed.

Implementations§

impl HalfBand2x

pub fn upsample(&mut self, sample: f32) -> [f32; 2]
