Kimitaka Tsutsumi, Yoichi Haneda, Ken'ichi Noguchil, Hideaki Takada

ICASSP 2018accepted

A method to create multipoles comprising a cluster of focused sources by using a linear loudspeaker array has recently been investigated. Directivities in a listening area were confirmed with examples of primitive multipoles such as dipoles and quadrupoles. This paper describes a method to create a…
