Our system scales across standalone mobile-class devices, from a HoloLens to a modern smart phone. Audio propagation in real-world scenes exhibits perceptually salient effects that complement visuals. These include diffraction losses from obstruction, re-direction (\u201cportaling\u201d) of sounds around physical doorways and corners, and reverberation in complex geometries with multiple connected spaces. Such effects are necessary in mixed reality to achieve a sense of presence for virtual people and things within the real world, but have so far been computationally infeasible on mobile devices. We propose a novel cloud-enabled system that enables such immersive audio-visual scenarios on untethered mixed reality devices for the first time.<\/p>\n<p><a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" rel=\"noopener noreferrer\" target=\"_blank\" href=\"https:\/\/aka.ms\/mracoustics\">Talk and Demo can be viewed here<span class=\"sr-only\"> (opens in new tab)<\/span><\/a><\/p>\n<div id=\"attachment_678720\" style=\"width: 1505px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-678720\" class=\"wp-image-678720 size-full\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2020\/07\/PAHololens_Architecture.png\" alt=\"System Architecture\" width=\"1495\" height=\"484\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2020\/07\/PAHololens_Architecture.png 1495w, https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2020\/07\/PAHololens_Architecture-300x97.png 300w, https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2020\/07\/PAHololens_Architecture-1024x332.png 1024w, https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2020\/07\/PAHololens_Architecture-768x249.png 768w\" sizes=\"auto, (max-width: 1495px) 100vw, 1495px\" \/><p id=\"caption-attachment-678720\" class=\"wp-caption-text\">We propose a novel system architecture where an &#8220;acoustic map&#8221; in the cloud stores acoustic simulation data that are bound to various locations in the world (such as via Azure Spatial Anchors).<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>We describe the first system for physically-based wave acoustics including diffraction effects within a holographic experience shared by multiple untethered devices.
