HannWindow()

std::vector< double > MayaFlux::Nodes::Generator::HannWindow

(

size_t

length

)

Creates a Hann window function.

Parameters

length

Number of samples in the window

Returns

Vector containing the window function values

The Hann window (sometimes called Hanning) is a bell-shaped window function that tapers smoothly to zero at both ends. It's commonly used for:

• Smoothing signal transitions
• Reducing spectral leakage in frequency domain analysis
• Creating envelope shapes for synthesis

Mathematical formula: w(n) = 0.5 * (1 - cos(2π*n/(N-1)))
