Abstract

With the rise of virtual reality, there is a demand for recording and recreating real-world experiences that allow users to move throughout audio-visual scenes. Sound field translation achieves this by building an equivalent environment of virtual sources to recreate the recording spatially. However, combining multiple microphone array recordings and dealing with mix fields of exterior and interior together is difficult. In this paper, we explain a novel method of virtual navigation by representing complex sound fields by distributed virtual higher order sound sources. The technique combine recordings from spatially separated microphones and decompose them to a sparse representation of multiple higher order sources. The method can be thought of sound field decomposition into a grid of higher order sources. We show the method can be used in VR applications involving navigation within complex sound scenes.
