In mathematics, a topological space X is said to be spectral if

1) X is compact and T₀;
2) The set C(X) of all compact- open subsets of (X,Ω) is a sublattice of Ω and a base for the topology;
3) X is sober, that is any closed set F which is not a closure of a singleton {x} is a union of two closed sets which differ from F.

Spectral widthIn telecommunication, spectral width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications appl	Spectral maskingSpectral masking is a sound effect that arises from the analysis of two sound-files. The created effect is a third sound-file that is composed of the loudest parts of the analyzed sound-files. A frequency domain version of temporal masking, spectral maski	Spectral classIn astronomy the term spectral class refers to classifying objects according to their spectral lines, which indicate an object's chemical composition. It can be used to refer to the classification of: Stars Asteroids Astronomy.
Spectral theoremIn mathematics, particularly linear algebra and functional analysis, the spectral theorem is a collection of results about linear operators or about matrices. In broad terms the spectral theorem provides conditions under which an operator or a matrix can	SpectralismSpectralism is a musical genre originating in France in which waveforms are broken down, and then recreated into musical forms.
