Abstract:
Systems and methods are provided for generating and rendering an enhanced audiovisual recording of a user, which may be used for multiuser communication, e.g., in Virtual Reality. Such an enhanced recording may be generated by determining a face orientation of the user in the audiovisual recording, and generating orientation data specifying an orientation which represents said determined face orientation. During rendering, the audio data may be rendered based on the orientation data, namely by rendering the audio data as a spatial audio source having a spatial direction which is congruent with the face orientation of the user in a visual representation of the user. Accordingly, the spatial direction of the voice of the user may better match the user's face direction in the user's visual representation.
