Struct Correlogram 

pub struct Correlogram { /* private fields */ }

Running autocorrelation matrix: each row is the autocorrelation of a frame.

Implementations

impl Correlogram

pub fn new(max_lag: usize) -> Self

pub fn push_frame(&mut self, frame: &[f32])

Push a signal frame and compute its autocorrelation.

pub fn get_frame(&self, t: usize) -> Option<&Vec<f32>>

Get the autocorrelation for frame t.

pub fn num_frames(&self) -> usize

Number of frames.

pub fn max_lag(&self) -> usize

Max lag.

pub fn average(&self) -> Vec<f32>

Average autocorrelation across all frames (pitch salience curve).

pub fn clear(&mut self)

Clear all frames.
