Abstract Fiber optic infrastructure is essential in the transmission of data of all kinds, both for the long haul and shorter distances in cities. Optical fibers are also preferred for data infrastructures inside buildings, especially in highly secur

This paper is focused on the simulation of line array source that consists of eight separate loudspeaker enclosures of the same type having some directional characteristics influenced by the position within the line array. The influence on these char

A novel method for audio declipping based on sparsity is presented. The method incorporates psychoacoustic information by weighting the transform coefficients in the $\ell_{1}$ minimization. Weighting leads to an improved quality of restoration while

This paper deals with design of digital bandpass filters for fixed-point arithmetic that fulfills requirements of IEC 61260–1 standard for fractional-octave-band filters. The filters use coupled form and downsampling that provides good approximatio

Capturing stereophonic room impulse responses for simulation of spatial impression of an acoustic space, for example for music production, is time consuming and expensive, especially when large database of well-recognized music spaces is needed. Howe

The impact of changes in a speaker's vocal effort on the performance of automatic speech recognition has largely been overlooked by researchers and virtually no speech resources exist for the development and testing of speech recognizers at all vocal
