Struct Window
pub struct WindowPlan { /* private fields */ }Expand description
Owned f64 window coefficients for 1..=1048576 samples. Construction evaluates cosines/allocates on a control thread; application allocates nothing. N=1 is unity for every family/convention. Tiny negative rounded taps are retained. Coherent gain and energy are computed from actual coefficients; zero-sum windows return no equivalent noise bandwidth. No automatic gain correction, overlap/add policy, nonfinite sanitization or native deadline guarantee.
Implementations§
§impl WindowPlan
impl WindowPlan
pub fn new( kind: WindowKind, convention: WindowConvention, size: usize, ) -> Result<Self, WindowError>
pub fn coefficients(&self) -> &[f64]
pub fn coherent_gain(&self) -> f64
pub fn coherent_gain(&self) -> f64
Mean coefficient, for coherent-bin amplitude correction on the caller.
pub fn equivalent_noise_bandwidth(&self) -> Option<f64>
pub fn equivalent_noise_bandwidth(&self) -> Option<f64>
N*energy/sum^2 in FFT-bin units, or None for exact zero sum.
pub fn apply(&self, samples: &mut [f64]) -> Result<(), WindowError>
pub fn apply(&self, samples: &mut [f64]) -> Result<(), WindowError>
Exact length required, rejected before mutation. Nonfinite audio propagates.
