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