BlackmanWindow()

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

(

size_t

length

)

Creates a Blackman window function.

Parameters

length

Number of samples in the window

Returns

Vector containing the window function values

The Blackman window provides better sidelobe suppression than Hamming or Hann windows, making it useful for:

• High-quality spectral analysis
• Applications requiring minimal spectral leakage
• Creating smooth envelopes with minimal artifacts

Mathematical formula: w(n) = 0.42 - 0.5*cos(2π*n/(N-1)) + 0.08*cos(4π*n/(N-1))
