BartlettWindow	A Bartlett window function.
BlackmanHarrisNuttall
BlackmanWindow	A Blackman window function.
CosineWindow	A Cosine window function.
FFT	Wrapper for calling a hopefully Fast Fourier transform.
FloatFFT	Computes 1D Discrete Fourier Transform (DFT) of complex and real, single precision data.
GaussWindow	A Gauss window function.
HammingWindow	A Hamming window function.
HannWindow	A Hann window function.

ScaledHammingWindow
TriangularWindow	A Triangular window function.
WindowFunction	A Window function represents a curve which is applied to a sample buffer to reduce the introduction of spectral leakage in the Fourier transform.
