Struct Duck 

pub struct Duck {
    pub threshold_db: f64,
    pub depth_db: f64,
    pub ratio: f64,
    pub attack: Duration,
    pub release: Duration,
    pub lookahead: Duration,
}

Sidechain ducking parameters. The trigger’s peak-hold envelope is converted to a gain reduction in dB, smoothed by attack/release and applied to the ducked signal.

Fields

threshold_db: f64

Trigger level above which ducking starts, in -96..=0 dBFS.

depth_db: f64

Maximum gain reduction, in 0..=96 dB.

ratio: f64

Compression ratio above the threshold, in 1..=100; reduction is capped by depth_db.

attack: Duration

Time to reach a deeper reduction, in 0..=5 seconds.

release: Duration

Time to recover after the trigger falls, in 0..=10 seconds.

lookahead: Duration

Interval by which ducking anticipates the trigger, in 0..=500 milliseconds.

Implementations

impl Duck

pub fn new(threshold_db: f64, depth_db: f64) -> Self
