Spectral
21Spectral flatness — is a measure used in digital signal processing to characterise an audio spectrum. A high spectral flatness indicates that the spectrum has a similar amount of power in all spectral bands this would sound similar to white noise, and the graph of… …
22Spectral modelling synthesis — Spectral Modeling Synthesis or simply SMS is an Acousic modeling approach for speech and other signals.SMS considers sounds as a combination of harmonic content and noise content. Harmonic components are identified based on peaks in the frequency …

24Spectral analysis — may refer to:* Spectrum analysis, in physics, a method of analyzing the chemical properties of matter from bands in their optical spectrum * Spectral theory, in mathematics, a theory that extends eigenvalues and eigenvectors to linear operators… …
25Spectral leakage — is an effect in the frequency analysis of signals where small amounts of signal energy are observed in frequency components that do not exist in the original waveform. The term leakage refers to the fact that it appears as if some energy has… …
26Spectral bands — are part of optical spectra of polyatomic systems, including condensed materials, large molecules etc. Each line corresponding to one level in atom splits in molecules. When the number of atoms is large, one gets continuum of energy levels, so… …

29Spectral band replication — (SBR) is a technology to enhance audio or speech codecs, especially at low bit rates and is based on harmonic redundancy in the frequency domain.It can be combined with any audio compression codec: the codec itself transmits the lower and… …
30Spectral signature — Spectral signatures are the specific combination of reflected and absorbed electromagnetic radiation at varying wavelengths which can uniquely identify an object. The spectral signature of an object is a function of 1) incidental EM wavelength… …
