Abstract
A method for high definition virtual acoustic display (VAD) based on a model called the ``Virtual Sphere (VS) model'' is introduced [S. Takane et al., Proc. ICAD2002(2002)]. This is named ADVISE (Acoustic Display based on the VIrtual SpherE model). In this paper, sound reproduction accuracy of ADVISE is first discussed via a computer simulation. Based on the simulation results, a practical way to determine necessary parameters for ADVISE is discussed, and these parameters are approximately given for the implementation under reasonable assumptions. Then, a real-time implementation of ADVISE is introduced. This system is realized as a binaural VAD with five floating-point DSPs (Texas Instruments TMS320C6701) hosted by a PC. Consideration of hardware performance and the programming in each DSP and the host computer is also mentioned. Results of a preliminary hearing experiment with this system showed a satisfactory performance.
