Abstract: Techniques of providing spatial audio to a remote user involve transmitting audio data in response to sensor information sent from the remote user. Along these lines, a user remote from a server computer may have a device that is configured to provide data from a sensor, e.g., a GPS, an accelerometer, an orientation sensor, a heart rate monitor, and the like. For example, the user may have granted access to such data via a specialized website hosted by the server computer. The sensor may then send, via a user device (e.g., a smartphone), sensor information that indicates the value of the state of the user. Based on the value of the state of the user, the server computer may then produce an audio file that includes audio data. The server computer may then transmit that audio data to the user device so that the user may hear the audio data.

Abstract: Techniques of performing involve providing interactive audio in addition to ambisonic audio in stereo tracks selected according to the occurrence of events in a media delivery system. For example, a user of a VR system observes a virtual environment that contains many virtual objects. The user may experience binaurally rendered audio played over N ambisonic channels from any number of virtual loudspeakers. In addition, the user may also activate another audio source by positioning his/her head at a certain angle, e.g., to look at a particular virtual object. As a specific example, when the user looks at a picture of a person, an audio track may play over a pair of stereo channels N+1 and N+2. Because they are stereo channels, there is no need to perform convolutions with HRTFs. In this way, audio may be provided for all virtual objects in the virtual environment with a small computational overhead.
