An analytical approach to 2.5D sound field reproduction employing circular distributions of non-omnidirectional loudspeakers

We present an approach targeting the physical reproduction of sound fields by means of circular distributions of non-omnidirectional loudspeakers. The approach does not compensate for loudspeaker properties which deviate from certain assumptions as conventional approaches do. It rather allows for the explicit consideration of these properties within some limits which are outlined. The focus of this paper lies on the modal incorporation of the loudspeaker´s spatio-temporal transfer function into the loudspeaker driving function.
