“…Hence a system to reproduce the synthesized sound pressure with ADVISE may be arbitrary such as the binaural and the transaural systems [20,21]. The system must have, however, the realtime tracability of the dynamic change in HRTFs due to the listener's movement.…”

“…The system must have, however, the realtime tracability of the dynamic change in HRTFs due to the listener's movement. As for the transaural systems, it should be noted that when the crosstalk cancellation is executed, the dynamic change in the transfer functions from the loudspeakers to the listener's ears caused by the movement of the listener in the reproduction environment should also be traced in real-time [20,22].…”

Abstract:A new theory for high definition Virtual Acoustic Display (VAD) based on a model called the ''Virtual Sphere (VS) model'' is introduced in this paper. This method is named ADVISE (Acoustic Display based on the VIrtual SpherE model). In ADVISE, a sphere-shaped boundary is defined around a listener, and the sound transmission from the sound source in the original field to the entrances of the listener's ears is divided into two parts. One consists of Head-Related Transfer Functions (HRTFs) corresponding to the points on the boundary of the virtual sphere, and the other consists of Room Transfer Functions (RTFs) from the sound source to the points on the boundary. Then, these two kinds of transfer functions are convolved in real-time, taking into account the dynamic changes in these functions due to the listener's head movement. The Kirchhoff-Helmholtz boundary integral equation is the theoretical basis of this idea. This equation represents that a sound field generated by sound sources outside a certain closed boundary can be synthesized by phantom monopole and dipole sources distributed on the boundary. In this paper, the theory of ADVISE is stated, then the features of ADVISE are described.

“…However, a 3-D audio system can position sounds anywhere around a listener and it has the ability to make the listener perceive that the sounds come from arbitrary points in space [1]. The applications of 3-D audio systems includes multimedia desktop computers, video games, audio and video conferencing, etc.…”

This paper describes a method for jointly designing the crosstalk cancellation filters to facilitate binaural rendering of audio through loudspeakers. The minimax criterion is used to design the immersive audio rendering filters having finite impulse responses for a single listener using loudspeakers. The work presented is applied to the traditional Atal-Schroeder crosstalk canceler structure. The minimax approach provides improved low frequency performance and a better overall separation of the direct path and cross path transfer functions than the conventional least-squares designs.

“…Among a number of algorithms to accomplish this task, the crosstalk cancellation (CTC) technique can, theoretically, provide the most accurate localization [1]. However, the traditional CTC systems are often associated with computational issues [2] and timbral distortions of the input signals [3].…”

SUMMARYThis paper presents an approximated virtual source imaging system based on crosstalk cancellation with a pair of closely spaced loudspeakers. Utilizing the frequency-dependent relative importance of sound localization cues, the proposed system provides separate approximations for the low-and high-frequency bands. Experimental results show that the system provides good approximations within ±55 • in the stereo dipole setup with natural sound quality. key words: sound cues, stereo dipole, virtual source imaging
