Abstract: Techniques are provided for spatial audio streaming using adaptive bitrate encoding and decoding in bandwidth limited virtual reality applications. A methodology implementing the techniques according to an embodiment includes calculating weight factors for audio channels associated with each of a plurality of microphones. The weight factors are based on the position and head angle, relative to the microphones, of a user wearing a head mounted display (HMD). The method also includes encoding and decoding the audio channels, for transmission to the HMD, at a selected bitrate, the bitrate based on the weight factor for the audio channel. The method further includes applying an adaptive gain compensation to each of the received and decoded audio channels, the gain compensation also based on the weight factor. The method further includes mixing the resulting gain compensated channels to generate a stereo audio signal to be played through speakers of the HMD.

Abstract: An example apparatus for generating real-time director's cuts includes a number of cameras to capture videos of a plurality of participants in a scene. The apparatus also includes a number of microphones to capture audio corresponding to each of the number of participants. The apparatus further includes a role-centric evaluator to receive views-of-participants and a role for each of the participants and rank the views-of-participants based on the roles. Each of the views-of-participants are tagged with one of the participants. The apparatus further includes a view broadcaster to display a highest ranking view-of-participant stream.
