Struct LoudnessNormalization 

pub struct LoudnessNormalization {
    pub gain_db: f64,
    pub integrated_lufs: f64,
    pub true_peak_dbtp: f64,
    pub peak_limited: bool,
    pub limiter_limited: bool,
}

A static gain to a loudness target, bounded by a true-peak ceiling and any master limiter.

Fields

gain_db: f64

Gain to apply, in dB.

integrated_lufs: f64

Integrated loudness after the gain, in LUFS.

true_peak_dbtp: f64

True peak after the gain, in dBTP.

peak_limited: bool

Whether a peak bound (ceiling or limiter) set the gain, leaving the result under target.

limiter_limited: bool

Whether the master limiter threshold was the binding bound.

Implementations

impl LoudnessNormalization

pub fn plan( report: &LoudnessReport, target_lufs: f64, ceiling_dbtp: f64, limiter_threshold: Option<f64>, ) -> Option<Self>

The gain that moves report to target_lufs, lowered so the true peak stays at or below ceiling_dbtp and, with a master limiter at linear limiter_threshold, the sample peak stays LIMITER_MARGIN_DB under it (the limiter detects sample peaks), so it never acts.

None without integrated loudness, or for non-finite inputs or a non-positive threshold.

pub fn linear_gain(&self) -> f64

The gain as a linear factor.
