Abstract: Real-world VR applications require to capture 3D sound with microphone setups that are hidden from the field-of-view of the 360-degree camera. Directional audio coding (DirAC) is a spatial sound capturing approach that can be applied to a wide range of compact microphone arrays. Unfortunately, its underlying parametric sound field model is often violated which leads to a degradation of the spatial sound quality. Therefore, we combine the non-linear DirAC processing with a linear beamforming approach that approximates the panning gains in DirAC such that the required amount of non-linear processing is reduced while increasing the robustness against model violations. Additionally, we derive a DOA estimator that enables 3D sound capturing with DirAC using compact 2D microphone arrays, which are often preferred in VR applications.
