Struct LoudnessMeter 

pub struct LoudnessMeter { /* private fields */ }

Real-time EBU R128 loudness meter.

Wraps ebur128 and exposes only the momentary / short-term / integrated values needed for the master strip readout.

Implementations

impl LoudnessMeter

pub fn new(channels: usize, sample_rate: u32) -> Result<Self, Error>

Create a new meter for the given channel count and sample rate.

pub fn channels(&self) -> usize

pub fn sample_rate(&self) -> u32

pub fn feed_interleaved(&mut self, samples: &[f32])

Feed a block of interleaved floating-point samples into the meter. This should be called every audio cycle so integrated loudness remains accurate; call Self::values only when the readout is actually needed (e.g. at the same rate as the VU meter snapshot).

pub fn values(&self) -> LoudnessValues

Return the current momentary / short-term / integrated loudness values.
