Abstract

This engineering brief evaluates the effectiveness of VHAP (virtual hemispherical amplitude panning) as a tool to create virtual height loudspeakers for Dolby Atmos 5.1.4 and Auro-3D 9.1 content. Previous studies showed that VHAP can effectively render elevated phantom images using only three or four ear-level loudspeakers. This study subjectively compared the 4-channel and 3-channel VHAP stimuli rendered against the original 5.1.4,in terms of sense of height, sense of width and overall quality of experience. Five excerpts from Dolby Atmos and Auro-3D content of different types (film, classical and EDM) were tested. Results suggest that VHAP is able to create virtual height loudspeakers with no significant level of degradation, and for certain stimuli it can be slightly preferred to the original.
