BeatAligner

Struct BeatAligner 

Source
pub struct BeatAligner { /* private fields */ }
Expand description

Performs beat-grid alignment on an audio signal.

Implementations§

Source§

impl BeatAligner

Source

pub fn new(config: BeatAlignConfig) -> Self

Creates a new aligner with the given configuration.

Source

pub fn config(&self) -> &BeatAlignConfig

Returns a reference to the current configuration.

Source

pub fn detect_downbeat(&self, samples: &[f32]) -> Option<usize>

Detects the approximate position of the first downbeat in samples.

Uses a simple energy-onset heuristic: returns the sample index of the frame with the highest short-window RMS energy.

Returns None when the signal is empty.

Source

pub fn align_to_grid(&self, samples: &[f32]) -> Option<BeatAlignResult>

Aligns samples to the configured beat grid.

Returns None when no reliable downbeat is found or the confidence is below an acceptable threshold.
