Abstract
The present document relates to methods and systems for setting up and managing two-dimensional or three-dimensional scenes for audio conferences. A conference controller (111, 175) configured to place L upstream audio signals (123, 173) within a 2D or 3D conference scene to be rendered to a listener (211) is described. The conference controller (111, 175) is configured to set up a X-point conference scene; assign L upstream audio signals (123, 173) to X talker locations (212); determine a maximum number N of downstream audio signals (124, 174) to be transmitted to the listener (211); determine N downstream audio signals (124, 174) from the L assigned upstream audio signals (123, 173); determine N updated talker locations for the N downstream audio signals (124, 174); and generate metadata identifying the updated talker locations and enabling an audio processing unit (121, 171) to generate a spatialized audio signal.
