Struct Normalizer 

pub struct Normalizer<'a> { /* private fields */ }

Available on crate feature normalize only.

One-shot normaliser: analyse + scale a buffer in place.

Implementations

impl<'a> Normalizer<'a>

pub fn new(sample_rate: u32, channels: &'a [Channel]) -> Self

Build a fresh normaliser. Default target is −23 LUFS (EBU R128 broadcast reference).

pub fn target_lufs(self, lufs: f64) -> Self

Set the target integrated loudness in LUFS.

pub fn true_peak_ceiling_dbtp(self, dbtp: f64) -> Self

Cap the post-normalisation true peak at this dBTP value. If the gain required to reach target_lufs would push the true peak above the ceiling, the gain is reduced.

pub fn normalize_in_place( &self, samples: &mut [f32], ) -> Result<NormalizeReport, Error>

Run the analyser, compute the gain, and scale samples in place. samples is interleaved ([L0 R0 L1 R1 ...]).

Returns the NormalizeReport describing what happened.

Errors

Anything AnalyzerBuilder::build or crate::Analyzer::push_interleaved can return.
