Object-Based Audio Reproduction using a Listener-Position Adaptive Stereo System

Document Thumbnail

Adapting a stereo reproduction system to the listener’s position allows for reproduction of 2D object-based audio with better localization accuracy when the listener is located outside of the sweet spot. The adaptation is composed of two parts: a compensation system that updates the loudspeakers feeds so that these are delivered to the listener with an intended magnitude and phase independently of the listening position, and an object-based rendering system using conventional panning algorithms. Initial localization simulations using the velocity and energy localization vectors predicted that the frequency-dependent panning can pan virtual audio sources outside of the loudspeaker region at low frequency. A perturbation analysis showed that, in practice, localization of audio objects is robust when these are panned between the stereo region, and that the localization of objects outside of the stereo region is both sensitive to errors and affected by the accuracy of the video tracking system and the homogeneity of the radiation pattern of the different loudspeakers of the system. These same results were corroborated with subjective tests.
