Spectral music — (or spectralism) refers to a musical composition practice where compositional decisions are often informed by the analysis of sound spectra. Computer based sound spectrum analysis using a Fast Fourier transform is one of the more common methods… … Wikipedia
Sound localization — refers to a listener s ability to identify the location or origin of a detected sound in direction and distance. It may also refer to the methods in acoustical engineering to simulate the placement of an auditory cue in a virtual 3D space (see… … Wikipedia
Spectral 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… … Wikipedia
Spectral method — Spectral methods are a class of techniques used in applied mathematics and scientific computing to numerically solve certain Dynamical Systems, often involving the use of the Fast Fourier Transform. Where applicable, spectral methods have… … Wikipedia

Spectral 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… … Wikipedia
sound — sound1 soundable, adj. /sownd/, n. 1. the sensation produced by stimulation of the organs of hearing by vibrations transmitted through the air or other medium. 2. mechanical vibrations transmitted through an elastic medium, traveling in air at a… … Universalium

Spectral slope — In astrophysics and planetary science, spectral slope is a measure of dependence of the reflectance on the wavelength.In digital signal processing, it is a measure of how quickly the spectrum of an audio sound tails off towards the high… … Wikipedia
Spectral glide — A spectral glide is a modification of the vowel quality of a tone (Erickson 1975, p.72). Since the vowel quality of a tone is determined by the overtones, spectrum, or timbre (all three terms being near equal) of that tone, a spectral glide is a… … Wikipedia
