3D audio technology based on binaural reproduction requires the Head-Related Transfer Function (HRTF) datasets to be available for all possible distance. However, due to the tedious work of measurement and large volume of resulting datasets, the HRTF is typically measured only for sources located at a fixed distance. In this paper, the concept of virtual(More)
Ambisonic decoder for irregular speaker arrays could be derived by optimization techniques. In terms of higher order reproduction system, the optimization program is hard to be guided to a large number of decoder coefficients. This paper describes a new method for higher order decoder based on the optimal symmetrical virtual microphone response (OSVMR). In(More)
Reproduction of a multi-source sound field is an important problem which should be considered in acoustic signal processing. A common method is to use an array of loudspeakers to reproduce the desired sound field where the driving function is the key issue. In this paper, a multi-source sound field reproduction method using cylindrical harmonic analysis is(More)
