Struct MeasuredMakeup 

pub struct MeasuredMakeup { /* private fields */ }

Measured auto-makeup gain that tracks the actual average gain reduction and compensates for it, rather than using a fixed heuristic like threshold × 0.5 × slope.

Uses an exponential moving average (EMA) of the applied gain reduction to determine how much makeup gain to apply.

Implementations

impl MeasuredMakeup

pub fn new(smoothing_ms: f32, sample_rate: u32) -> Self

Create a new measured auto-makeup.

• smoothing_ms — EMA time constant (e.g., 1000ms for slow tracking)
• sample_rate — audio sample rate

pub fn update(&mut self, gain_reduction_db: f32)

Update with the current gain reduction in dB (positive = reduction).

Call this once per sample (or once per frame with the frame’s GR).

pub fn makeup_db(&self) -> f32

Get the makeup gain in dB that compensates for average reduction.

pub fn makeup_linear(&self) -> f32

Get the makeup gain as a linear multiplier.

pub fn reset(&mut self)

pub fn set_smoothing(&mut self, smoothing_ms: f32, sample_rate: u32)

Update smoothing time (e.g., when sample rate changes).
