Abstract
Rendering audio for applications implemented in an MR or AR system, in a 3D environment. A method includes determining a location of a user device in the 3D environment. The method further includes accessing a set of spatial mapping data to obtain spatial mapping data for the determined location. The spatial mapping data includes spatial mapping of free-space points in the 3D environment. Data for each free-space point includes data related to audio characteristics at that free-space point. The spatial mapping data is based on data provided by users in the 3D environment. The method further includes applying the spatial mapping data for the determined location to one or more acoustic simulation filters. The method further includes using the one or more acoustic simulation filters with the spatial mapping data applied, rendering audio output for one or more applications implemented in the MR or AR system to a user.
