Struct DynamicLoudness 

pub struct DynamicLoudness { /* private fields */ }

Dynamic Loudness Compensation processor

Implements ISO 226 inspired loudness compensation using a 7-band dynamic EQ. At low volumes, boosts low and high frequencies to compensate for the ear’s reduced sensitivity (Fletcher-Munson effect).

Implementations

impl DynamicLoudness

pub fn new(channels: usize, sample_rate: f64) -> Self

Create a new DynamicLoudness processor

pub fn set_volume(&mut self, linear_volume: f64)

Set user volume as linear value (0.0 - 1.0) This is the main control input

pub fn set_volume_percent(&mut self, percent: f64)

Set user volume as percentage (0 - 100)

pub fn set_volume_db(&mut self, volume_db: f64)

Set user volume as dB

pub fn set_strength(&mut self, strength: f64)

Set strength (0.0 - 1.0, scales all compensation)

pub fn set_reference_volume_db(&mut self, ref_db: f64)

Set reference volume level in dB

pub fn set_transition_db(&mut self, transition_db: f64)

Set transition range in dB

pub fn set_enabled(&mut self, enabled: bool)

Enable or disable processing

pub fn set_sample_rate(&mut self, sample_rate: f64)

Update sample rate

pub fn process(&mut self, buffer: &mut [f64])

Process interleaved audio buffer

Coefficient ramps now track the per-block smoother within the buffer: each BLOCK_SIZE-frame chunk advances the smoothers, applies any changed band gain, then filters only that chunk’s frames. This avoids the end-of-buffer “zipper” that occurred when the whole buffer was filtered with only the final block’s coefficients. Total smoother advancement is unchanged (Σ chunk_frames == frames), so end-of-buffer state matches the previous behavior; buffers ≤ BLOCK_SIZE are filtered as a single block.

pub fn reset(&mut self)

Reset all filter states

pub fn loudness_factor(&self) -> f64

Get current loudness factor (for display)

pub fn get_band_gains(&self) -> [f64; 7]

Get current band gains (for display/metering)

pub fn is_enabled(&self) -> bool

Check if enabled

pub fn strength(&self) -> f64

Get strength
