Struct PitchTracker 

pub struct PitchTracker { /* private fields */ }

High-level streaming pitch tracker. Combines any PitchEstimator with a linear resampler that converts the host’s sample rate to the estimator’s target rate.

Feed it mono f32 audio at input_sample_rate via process. The tracker buffers internally and returns frames as they become available.

Implementations

impl PitchTracker

pub fn new<E: PitchEstimator + 'static>( estimator: E, input_sample_rate: u32, resample_chunk: usize, ) -> Result<Self>

Build a tracker from any concrete PitchEstimator.

pub fn from_boxed( estimator: Box<dyn PitchEstimator>, input_sample_rate: u32, resample_chunk: usize, ) -> Result<Self>

Build a tracker from an already-boxed estimator. Useful when the estimator type is decided at runtime (e.g. from a CLI flag).

pub fn algorithm(&self) -> &str

pub fn input_sample_rate(&self) -> u32

pub fn target_sample_rate(&self) -> u32

pub fn reset(&mut self)

pub fn process(&mut self, audio: &[f32]) -> Result<Vec<PitchFrame>>

Push mono f32 audio at input_sample_rate. Returns whatever frames the estimator produced after consuming this chunk. Empty at the start of the stream and after reset while the estimator’s internal buffer fills.
