Struct NoveltyDetector 

pub struct NoveltyDetector { /* private fields */ }

Tracks the slow running mean of the spectrum and reports how far the current spectrum sits from it.

Implementations

impl NoveltyDetector

pub fn new(sample_rate: u32) -> Self

Build a detector for a given sample rate (sets the per-hop smoothing so the effective window is NOVELTY_TAU seconds regardless of rate).

pub fn process(&mut self, spectrum: &[f32; 64]) -> f32

Consume one hop’s spectrum and return the novelty score (0 on the first hop, while the mean seeds). The running mean folds in the current spectrum after the measurement, so a boundary spikes before the mean absorbs it.
