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 () configured to place L upstream audio signals () within a 2D or 3D conference scene to be rendered to a listener () is described. The conference controller () is configured to set up a X-point conference scene; assign L upstream audio signals () to X talker locations (); determine a maximum number N of downstream audio signals () to be transmitted to the listener (); determine N downstream audio signals () from the L assigned upstream audio signals (); determine N updated talker locations for the N downstream audio signals (); and generate metadata identifying the updated talker locations and enabling an audio processing unit () to generate a spatialized audio signal. 130-.
