Abstract: Multiple sound systems are used to provide a realistic audio MR audio experience for one or more users. In one example, an MR space sound system has one or more speakers distributed within an MR space. MR device sound systems for users provides sound directly to the users wearing the MR devices. Audio signals representative of sound in the MR experience are mixed by each sound system to provide sounds that complement each other. Both sound systems provide sound to the users based on events occurring in the MR experience.

Abstract: A mobile device implemented method provides audio from a virtual audio source in an augmented reality view of a scene. The method includes operations of sending scene identification data to a server storing precomputed acoustic parameters for multiple scenes, receiving precomputed acoustic parameters corresponding to the scene, aligning the view to register the audio to the augmented reality view of the scene, and rendering and playing the audio using the obtained acoustic parameters.
