AB  - For consumer home entertainment, rendering spatial sound on multiple loudspeakers is important. Stimulated by the recent push for Virtual and Augmented Reality (VR/AR) applications, precise and inexpensive tracking devices have become available that can help to enhance the loudspeaker playback user experience for any type of setup from 2.0 (stereo) to 22.2 3D audio. By using the tracked listener position and digital signal processing, the sensation of a large “sweet area” and vastly increased spatial stability can be experienced by the listener, almost similar to what is known from wavefield synthesis (but at a small fraction of rendering effort and for a single listener). This paper describes an advanced user-tracked rendering system for multi-channel audio including a number of novel features (compensation of loudspeaker directivity pattern, consideration of room reverberation, and a simple parametrization for both aspects). The system’s subjective rendering performance for image stability is evaluated in a subjective test and shows marked improvement over non-tracked rendering. The described technology has been accepted for loudspeaker rendering in the upcoming MPEG-I Immersive Audio standard
