Abstract

A binaural rendering addon based on the EBU ADM Renderer has been developed, which renders Next Generation
Audio scenes using virtual loudspeaker systems. During development, two optimization approaches emerged
regarding rendering quality and efficiency. The first approach concerns the rendering of coherent signals from
different emitter positions, which is particularly relevant for virtual speakers since object positioning is based on
amplitude panning. The second approach concerns the reduction of computational costs when rendering the
binaural room response by using different virtual speaker layouts for the rendering of the direct path and of the
room response. To evaluate both approaches, a listening test was conducted. The results of this test showed that
each approach positively influenced either rendering quality or performance.
