Use of Position-Dynamic Binaural Synthesis in an Exemplary Auditory Augmented Reality Installation

Abstract:
In the context of augmented reality spatial audio using a position-dynamic binaural synthesis system is an appropriate approach to fuse virtual audio objects with the real listening environment. This contribution describes a possible technical realization of such a system. Several components are described which help to enable a plausible auditory simulation with a moving listener while keeping the computational effort in mind. The proposed system builds upon measured room impulse responses to avoid possible room divergence between the synthesized scene and real acoustic environment. Efficient approaches are presented to synthesize new BRIRs using very few measurements of the listening room and to realize a real-time convolution. These approaches are discussed on an exemplary installation for presenting audio information in the context of a museum exhibition with the aim to improve knowledge transfer.
