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 a plurality of upstream audio signals (123, 173) associated with a plurality of conference participants 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 with X different spatial talker locations (212) within the conference scene; assign the plurality of upstream audio signals (123, 173) to respective ones of the talker locations (212); determine a degree of activity of the plurality of upstream audio signals (123, 173); determine a dominant one of the plurality of upstream audio signals (123, 173); and emphasize the dominant upstream audio signal (123, 173).

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 plurality of upstream audio signals to respective ones of the talker locations; determine a degree of activity of the plurality of upstream audio signals at a time instant; determine a dominant one of the plurality of upstream audio signals at the time instant based on the degrees of activity of the plurality of upstream audio signals at the time instant; assign the dominant upstream audio signal to a first of the X talker locations; and emphasize the dominant upstream audio signal at the time instant by rotating the X talker locations around a head of the listener to yield updated talker locations such that the updated talker location of the dominant upstream audio signal is the updated talker location closest to a midline in front of a head of the listener. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)

56. ) A method for placing a plurality of upstream audio signals associated with a plurality of conference participants within a 2D or 3D conference scene to be rendered to a listener, wherein the method comprises
setting up a X-point conference scene with X different spatial talker locations within the conference scene, X being an integer, X> - 0;
assigning the plurality of upstream audio signals to respective ones of the talker locations; determining a degree of activity of the plurality of upstream audio signals, at a time instant; determining a dominant one of the plurality of upstream audio signals at the time instant based on the degrees of activity of the plurality of upstream audio signals at the time instant; assigning the dominant upstream audio signal to a first of the X talker locations; and emphasizing the dominant upstream audio signal at the time instant by rotating the X talker locations around a head of the listener to yield updated talker locations such that the updated talker location of the dominant upstream audio signal is the updated talker location closest to a midline in front of a head of the listener. - View Dependent Claims (57)
