A comprehensive study was conducted to explore the effects of listening angle on crosstalk cancellation in spatial sound reproduction using two-channel stereo systems. The intention is to establish a sustainable configuration of crosstalk cancellation system (CCS) that best reconciles the separation performance and the robustness against lateral head movement, not only in theory but also in practice. Although crosstalk can in principle be suppressed using multichannel inverse filters, the CCS… 

Channel separation of crosstalk cancellation systems with mismatched and misaligned sound sources.

An analytical model of crosstalk cancellation systems in a free field which takes into account the scattering and spatial characteristics of the sound sources is presented, finding that the channel separation of the crosStalk cancellation system is most sensitive to the misalignment of the subtended angle of thesound sources.

Objective evaluation of the sweet spot size in spatial sound reproduction using elevated loudspeakers.

A follow-up evaluation of the performance of the three inversion techniques when the above mentioned conditions are relaxed suggests that when the loudspeakers are placed at elevated positions, a wider effective area is obtained.

Two listeners crosstalk cancellation system modelled by four point sources and two rigid spheres

In virtual acoustic imaging systems, the perception of a sound source anywhere in space can theoretically be reproduced for one listener by using only two loudspeaker and an appropriate set of

Loudspeaker arrays for transaural reproduction

Transaural rendering allows for the reproduction of binaural audio material without the need of wearing headphones. This is achieved by the use of cross talk cancellation systems, which are generally

A Stereo Crosstalk Cancellation System Based on the Common-Acoustical Pole/Zero Model

Simulation results demonstrate that the proposed stereo crosstalk cancellation system based on common-acoustical pole/zero (CAPZ) models can reduce computational cost with comparable crosStalk cancellation performance.

Sound localization in individualized and non-individualized crosstalk cancellation systems.

The direction-dependent analysis showed that mismatch and lack of individualization yielded a substantially degraded performance for targets placed outside of the loudspeaker span and behind the listeners, showing relevance of individualized CTC systems for those targets.

Spatial sound field synthesis and upmixing based on the equivalent source method.

A synthesis and upmixing approach inspired by the equivalent source method (ESM) yielded the best spatial sound field synthesis in terms of the reproduction error, timbral quality, and spatial quality.

This work proposes a robustness measure to evaluate the performance of crosstalk cancelers as a function of loudspeaker spacing, and provides a simple empirically-derived equation for determining the optimum loudspeakers spacing in a given situation.

A joint least squares optimization of both the filter coefficients and the modeling delay is performed in order to obtain a robust solution for acoustic crosstalk cancellation.

Optimal design of loudspeaker arrays for robust cross-talk cancellation using the Taguchi method and the genetic algorithm.

The results reveal that large number of loudspeakers, closely spaced configuration, and optimal control point design all contribute to the robustness of cross-talk cancellation systems (CCS) against head misalignment.

Optimal source distribution for binaural synthesis over loudspeakers.

A conceptual monopole transducer is introduced whose position varies continuously as frequency varies and gives a minimum processing requirement of the binaural signals for the control to be achieved and all the above problems either disappear or are minimized.

Errors in two-point sound reproduction.

The basic physical processes involved in producing the cross-talk cancellation that enables the reproduction of the desired signals is revisited here by using a simple two source/two field point free field model.

Generalized transaural stereo and applications

Transaural stereo is a signal-theoretic means for accurately generating precisely defined signals at the ears of a listener by using loudspeakers. As such, it is the basis for true loudspeaker-based

A desktop audio system that incorporates several novel design requirements and integrates vision-based listener-tracking for accurate spatial sound reproduction is presented and a method of pinna classification is presented that allows users to select a set of parameters that closely match their individual listening characteristics.

The stereo dipole : A virtual source imaging system using two closely spaced loudspeakers

A system comprising only two closely spaced loudspeakers can create very convincing virtual images around a single listener. It is demonstrated that such a system is very robust with respect to head

In the present work it is demonstrated that the L-curve criterion is robust with respect to the errors in a real measurement situation and shown that the more conventional generalized cross-validation approach for the present tire noise studies is superior.
