Abstract: A first device obtains, from the array, several audio signals and processes the audio signals to produce a speech signal and one or more ambient signals. The first device processes the ambient signals to produce a sound-object sonic descriptor that has metadata describing a sound object within an acoustic environment. The first device transmits, over a communication data link, the speech signal and the descriptor to a second electronic device that is configured to spatially reproduce the sound object using the descriptor mixed with the speech signal, to produce several mixed signals to drive several speakers.

Abstract: Channels of audio data in a spatial audio object are associated with any one or more of a direction and a location of one or more recorded sounds, which channels are to be reproduced as spatial sound. A visualized spatial sound object represents a snapshot/thumbnail of the spatial sound. To preview the spatial sound (by experiencing its snapshot or thumbnail), a user manipulates the orientation of the visualized spatial sound object, and a weighted downmix of the channels is rendered for output as a spatial preview sound, e.g., a single output audio signal is provided to a spatial audio renderer; one or more of the channels that are oriented toward the user are emphasized in the preview sound, more than channels that are oriented away from the user. Other aspects are also described and claimed.

Abstract: A head-mounted display system is disclosed that includes a housing; a visual system associated with the housing to facilitate image and/or video display; a wearable support connectable to the housing; and an audio component pivotably connected to the support such that the audio component is movable between a first position in which the audio component is in general alignment with the support, and a second position in which the audio component is out of general alignment with the support. Movement from the first position to the second position transitions the audio component from a first mode (i.e., an extra-aural mode) in which sound is projected through a first port in communication with a driver to a user to a second mode (i.e., an intra-aural mode) in which sound is projected through a second port in communication with the driver to the user.
