Claim Text:
1. A conference controller configured to place L upstream audio signals associated with respective L conference participants within a 2D or 3D conference scene to be rendered to a listener; L being an integer, L>1; wherein the conference controller is configured to set up a X-point conference scene with X different spatial talker locations within the conference scene, X being an integer, X>0; assign the L upstream audio signals to the X talker locations; determine N downstream audio signals from the L assigned upstream audio signals based on the L upstream audio signals, N being an integer, N<X; wherein determining N downstream audio signals comprises determine N updated talker locations for the N downstream audio signals, respectively, based on the talker locations which the L upstream audio signals are assigned to; assign the first downstream audio signal to a first of the N updated talker locations; and generate metadata identifying the updated talker locations and enabling an audio processing unit to generate a spatialized audio signal based on the N downstream audio signals; wherein when rendering the spatialized audio signal to the listener, the listener perceives the N downstream audio signals as coming from the N updated talker locations, respectively.
