Struct BarGrid 

pub struct BarGrid { /* private fields */ }

A beat clock driven by the tempo estimate, phase-locked to the onset envelope.

Implementations

impl BarGrid

pub fn new(sample_rate: u32) -> Self

A grid for sample_rate, stopped until the first positive tempo.

pub fn process(&mut self, bpm: f32, onset: f32) -> GridPosition

Advance one hop against the current tempo estimate and onset envelope.

bpm is the tempo tracker’s estimate and onset the raw envelope — raw for the same reason the tempo tracker reads it raw (see gain): peak normalization is a slow AGC that would reweight the history the lock averages over.
