The effect of auditory rendering on perceived movement: Loudspeaker density and HRTF

Abstract

Until recently, multiple speaker systems for Virtual Environment (VE) applications were limited to a few front and rear speakers. Utilizing the Virtual Audio Server (VAS) with a Vector Base Amplitude Panning (VBAP) algorithm for multiple speaker control, an array of 24 speakers was constructed to test large speaker configurations. Localization of complex movement was superior with the 24-speaker system, compared to an 8-speaker configuration or HRTF spatialization.
