Real-time Spectral Attenuation Based Analysis and Resynthesis, Spectral Modification, Spectral Accumulation, and Spectral Evaporation; Theory, Implementation, and Compositional Implications

چکیده
Building upon convolution-based EQ (Settel and Lippe 1997 rev. 2001) spectral analysis data is utilized to attenuate FFT bins (derived from an FFT analysis of noise) to create an FFT/IFFT-based subtractive analysis/resynthesis module. Techniques for modification of analysis data prior to resynthesis, producing a variety of effects, are examined and demonstrated. Methods for retaining information from previous analysis (spectral accumulation) and for systematic data attrition (spectral evaporation) are introduced. A MaxMSP graphic user interface, designed by the author for implementation of the techniques, is discussed and described. Compositional implications are examined and musical examples are utilized to illustrate potential musical applications.

Fast Unsupervised Automobile Insurance Fraud Detection Based on Spectral Ranking of Anomalies
Collecting insurance fraud samples is costly and if performed manually is very time consuming. This issue suggests usage of unsupervised models. One of the accurate methods in this regards is Spectral Ranking of Anomalies (SRA) that is shown to work better than other methods for auto insurance fraud detection specifically. However, this approach is not scalable to large samples and is not appro...
متن کاملOn Generalization of Sturm-Liouville Theory for Fractional Bessel Operator
In this paper, we give the spectral theory for eigenvalues and eigenfunctions of a boundary value problem consisting of the linear fractional Bessel operator. Moreover, we show that this operator is self-adjoint, the eigenvalues of the problem are real, and the corresponding eigenfunctions are orthogonal. In this paper, we give the spectral theory for eigenvalues and eigenfunctions...

Abstract The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...
متن کاملFree and Forced Transverse Vibration Analysis of Moderately Thick Orthotropic Plates Using Spectral Finite Element Method
In the present study, a spectral finite element method is developed for free and forced transverse vibration of Levy-type moderately thick rectangular orthotropic plates based on first-order shear deformation theory. Levy solution assumption was used to convert the two-dimensional problem into a one-dimensional problem. In the first step, the governing out-of-plane differential equations are tr...
متن کاملTarget Detection Improvements in Hyperspectral Images by Adjusting Band Weights and Identifying end-members in Feature Space Clusters
Spectral target detection could be regarded as one of the strategic applications of hyperspectral data analysis. The presence of targets in an area smaller than a pixel’s ground coverage has led to the development of spectral un-mixing methods to detect these types of targets. Usually, in the spectral un-mixing algorithms, the similar weights have been assumed for spectral bands. Howe...
