Struct SinglePoleFilterQ15 

pub struct SinglePoleFilterQ15 { /* private fields */ }

Q15 single-pole recursive low-pass or high-pass filter (same recurrence as SinglePoleFilter). decay is Q1.15 in 0..1 (larger → lower cutoff).

Implementations

impl SinglePoleFilterQ15

pub fn lowpass(decay: q15) -> Self

Creates a single-pole low-pass filter from Q15 decay x.

pub fn highpass(decay: q15) -> Self

Creates a single-pole high-pass filter from the same Q15 decay used by SinglePoleFilterQ15::lowpass.

pub fn lowpass_from_f32(decay: f32) -> Self

Quantizes a floating-point decay in 0.0..1.0 to Q15 and builds a low-pass.

pub fn highpass_from_f32(decay: f32) -> Self

Quantizes a floating-point decay in 0.0..1.0 to Q15 and builds a high-pass.

pub fn process(&mut self, x: q15) -> q15

Processes a single Q15 input sample and returns the filtered output.

pub fn reset(&mut self)

Resets the filter’s delay state to zero.
