This paper investigates the rendering of moving sound sources in the context of real-world loudspeaker arrays and virtual loudspeaker arrays for binaural listening in VR experiences. Near Field compensated Higher Order Ambisonics (HOA) and Vector Base Amplitude Panning (VBAP) are investigated for both spatial accuracy and tonal coloration with moving sound source trajectories. A subjective listening experiment is presented over 6, 26, and 50 channel real and virtual spherical loudspeaker configurations to investigate accuracy of spatial rendering and tonal effects. The results show the applicability of different degrees of VBAP and HOA to moving source rendering and illustrate subjective similarities and differences to real and virtual loudspeaker arrays.
