Sound Field Reproduction Employing Non-Omnidirectional Loudspeakers

Document Thumbnail

In this paper we treat sound field reproduction via circular distributions of loudspeakers. The general formulation of the approach has been recently published by the authors. In this contribution, we concentrate on the employment of secondary sources (i.e.~loudspeakers) whose spatio-temporal transfer function is not omnidirectional. The presented approach allows to treat each spatial mode of the secondary source's spatio-temporal transfer function individually. We finally outline the general process of incorporating spatio-temporal transfer functions obtained from microphone array measurements.
