Struct GoertzelDetectorQ15 

pub struct GoertzelDetectorQ15 { /* private fields */ }

Q15 Goertzel detector: same two-pole recurrence as GoertzelDetector, with Q2.14 2 cos(ω) and i32 delays so a typical block (N ≲ 256) does not wrap.

Implementations

impl GoertzelDetectorQ15

pub fn new(target_freq_hz: f32, sample_rate_hz: f32) -> Self

Creates a detector tuned to target_freq_hz at the given sample_rate_hz.

pub fn process_sample(&mut self, x: q15)

Feeds one Q15 input sample into the detector.

pub fn magnitude(&self) -> q15

Magnitude of the target bin, normalized by N/2 like GoertzelDetector::magnitude.

pub fn reset(&mut self)

Resets the detector’s internal state to start a new detection block.
