Struct BeatGrid 

pub struct BeatGrid {
    pub beats: Vec<usize>,
    pub beats_fractional: Vec<f64>,
    pub bpm: f64,
    pub sample_rate: u32,
}

Beat grid information for a 4/4 track.

Fields

beats: Vec<usize>

Sample positions of detected beat onsets (integer, for backward compatibility with existing code that indexes into sample buffers).

beats_fractional: Vec<f64>

Fractional-sample beat positions for sub-sample precision. Length matches beats; each value is a refinement of the corresponding integer beat position.

bpm: f64

Estimated BPM.

sample_rate: u32

Sample rate.

Implementations

impl BeatGrid

pub fn beat_interval_samples(&self) -> f64

Returns the interval between beats in samples.

pub fn snap_to_grid(&self, position: usize) -> usize

Snaps a sample position to the nearest beat grid position.

pub fn snap_to_grid_fractional(&self, position: f64) -> f64

Snaps a sample position to the nearest fractional beat grid position. Returns a sub-sample-accurate position.
