Struct Panning
pub struct PanningGains { /* private fields */ }Expand description
Immutable CONTROL-prepared actual f64 coefficients. Pan is -1..1. The seven curves are linear, balanced, sine, sine^1.5, sine², square-root and power^.75. UnityCenter scales by the rounded reciprocal of the ideal center gain, making both center channels unity and boosting endpoints up to 2. No clipping, input scan or limiter. Endpoints/center are explicit; mirrored pans swap identical actual gains. Trigonometry and powers occur here, never in per-frame processing.

§impl PanningGains
impl PanningGains
pub fn new( pan: f64, law: PanningLaw, normalization: PanningNormalization, ) -> Result<Self, PanningError>
pub fn pan(&self) -> f64
pub fn law(&self) -> PanningLaw
pub fn normalization(&self) -> PanningNormalization
pub fn gains(&self) -> [f64; 2]
pub fn left(&self) -> f64
pub fn right(&self) -> f64
pub fn endpoint_gain(&self) -> f64
pub fn endpoint_gain(&self) -> f64
Theoretical endpoint maximum, not a floating execution error certificate.
pub fn quantize_f32(&self) -> PanningGains32
pub fn quantize_f32(&self) -> PanningGains32
Explicit coefficient rounding. Requested pan/curve metadata is retained; actual native f32 gains need not satisfy an ideal power equality exactly.
