When making a convincing mixed reality experience, audio consideration is a must. Great audio can transport the HoloLens wearer to another place or time, help navigate 3D interfaces, or blur the lines of what is real and what is a hologram. Using a location-based trigger (hotspot), we will dial up a fun example of how well spatial sound works with the HoloLens.
In this tutorial, we will be creating a spatialized audio object that revolves around a target object. You will be able to stay put and listen as the hologram travels the space around you, or move about and explore the changing audio freely.
