Placement of talkers in 2D or 3D conference scene

摘要

The present document relates to setting up and managing two-dimensional or three-dimensional scenes for audio conferences. A conference controller (111, 175) configured to place an upstream audio signal (123, 173) associated with a conference participant within a 2D or 3D conference scene to be rendered to a listener (211) is described. An X-point conference scene with X different spatial talker locations (212) is set up within the conference scene, wherein the X talker locations (212) are positioned within a cone around a midline (215) in front of a head of the listener (211). A generatrix (216) of the cone and the midline (215) form an angle which is smaller than or equal to a pre-determined maximum cone angle. The upstream audio signal (123, 173) is assigned to one of the talker locations (212) and metadata identifying the assigned talker location (212) are generated, thus enabling a spatialized audio signal.
