Enum Normalizer 

pub enum Normalizer {
    Power,
    Magnitude,
    DecibelsDb {
        floor_db: f32,
    },
    PowerSqrt,
    LogMagnitude,
    MeanNormalized,
    LocalMax {
        radius: usize,
    },
}

Variants

Power

Magnitude

DecibelsDb

10*log10(power), mapped to [0,1] between floor_db and 0 dB

Fields

floor_db: f32

Noise floor in dB, e.g. -80.0. Values below are clamped to 0.

PowerSqrt

Square root of power — perceptually between Power and Magnitude, compresses dynamic range less aggressively than Power

LogMagnitude

log1p(magnitude) — log compression without needing a dB floor, good when signal has a lot of near-zero bins

MeanNormalized

Each bin normalized by the mean power across the frame — emphasizes spectral shape rather than absolute energy. Good for comparing frames with very different loudness.

LocalMax

Each bin divided by its local neighborhood max (per-bin across time). Makes quiet features visible that global normalization would crush.

Fields

radius: usize

Half-window size in bins

Trait Implementations

impl Clone for Normalizer

fn clone(&self) -> Normalizer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Normalizer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Normalizer

fn default() -> Normalizer

Returns the “default value” for a type.

impl PartialEq for Normalizer

fn eq(&self, other: &Normalizer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Normalizer

fn partial_cmp(&self, other: &Normalizer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for Normalizer

impl StructuralPartialEq for Normalizer
