Circulant and elliptic feedback delay networks for artificial reverberation

The feedback delay network (FDN) has been proposed for digital reverberation. Also proposed with similar advantages is the digital waveguide network (DWN). This paper notes that the commonly used FDN with an N × N orthogonal feedback matrix is isomorphic to a normalized digital waveguide network consisting of one scattering junction and a vector transformer joining N reflectively terminated bra...

Time-varying feedback matrices in feedback delay networks and their application in artificial reverberation.

This paper introduces a time-variant reverberation algorithm as an extension of the feedback delay network (FDN). By modulating the feedback matrix nearly continuously over time, a complex pattern of concurrent amplitude modulations of the feedback paths evolves. Due to its complexity, the modulation produces less likely perceivable artifacts and the time-variation helps to increase the livelin...

Time Preference and its Effects on Intertemporal

Time preference has a peculiar role in determining the level of economic activities. Time preferenceis the most important origin of interest rate. In this paper we study the founders and defenders'viewpoints about time preference and then we try to criticize them. It seems that discounting futureutilities is resulting from irrationality and it is ethically indefensible too. From mathematical as...

Modeling of active reverberation by time delay estimation

This paper explores the statistical properties of underwater reverberation present in active sonar systems. The interference to signal processing which results from reverberation can be extensive, and is particularly acute when the boundaries (surface, bottom) of the water column are nearby. Of particular interest are situations where there may be weak targets masked by reverberation dominating...
