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. Main composers include Gerard Grisey and Tristan Murail. Influences include Olivier Messiaen and Karlheinz Stockhausen. French Spectral lineA spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from an excess or deficiency of photons in a narrow frequency range, compared with the nearby frequencies. Spectral lines are the result of interaction bet Spectral density Spectral envelope Spectral method Spectral radius Spectral evidence Spectral theory Spectral graph theory Spectral Bat Spectral space
