AB  - In this paper we present our recent activities on building facilities to drive research and development on 3D sound field capturing and reproduction. We developed a 64-channel spherical microphone array, the ViReal Mic, and a 122-channel loudspeaker array system, the ViReal Dome. The ViReal Mic is a microphone array whose microphone capsules are mounted on a rigid sphere, with the positions determined by the spherical Fibonacci spiral. The ViReal Dome is a loudspeaker array system consisting of 122 active coaxial loudspeakers. We present the details of the developed systems and discuss directions of future research.
