摘要： A system, apparatus and method are provided for updating spatial audio content in augmented reality based on a real-world speed and/or location of a consumer of the content. A moving spatial audio location may change location with time during a predetermining running time of the content. The spatial audio content is perceived as originating from a spatial audio location. Depending on the movement of the consumer, and a predicted alignment-time with of a point-of-interest and corresponding spatial audio content, a spatial audio location may be moved such that the spatial audio content aligns the point-of-interest based on an updated location of the consumer.
