LookaheadDetector

Struct LookaheadDetector 

Source
pub struct LookaheadDetector { /* private fields */ }
Expand description

Detektor gain reduction berbasis sliding maximum pada window lookahead.

Detektor dipisahkan dari delay audio supaya beberapa channel bisa berbagi satu detektor — dasar untuk stereo-linked limiting (LimiterProcessor).

Implementations§

Source§

impl LookaheadDetector

Source

pub fn new( sample_rate: f32, ceiling_db: f32, release_ms: f32, lookahead_ms: f32, ) -> Self

§Arguments
  • sample_rate - Frekuensi sampling (Hz)
  • ceiling_db - Batas keluaran (dBFS, mis. -1.0)
  • release_ms - Waktu pemulihan gain reduction (ms)
  • lookahead_ms - Panjang window lookahead (ms)
Source

pub fn latency_samples(&self) -> usize

Jumlah sample delay audio yang menyertai detektor ini.

Source

pub fn current_gain(&self) -> f32

Source

pub fn ceiling_linear(&self) -> f32

Source

pub fn process_input_peak(&mut self, input_peak: f32) -> f32

Memasukkan puncak input satu frame dan mengembalikan gain yang harus dipakai.

Attack bersifat instan: begitu puncak baru masuk window, gain langsung turun sehingga tidak ada sampel yang lolos di atas ceiling. Release dihaluskan eksponensial, dengan min-hold agar gain tidak naik sebelum transient melewati output.

Source

pub fn reset(&mut self)
