Abstract

The present document relates to audio conference systems. In particular, the present document relates to the mapping of soundfields within an audio conference system. A conference multiplexer (110, 175, 210, 400) configured to place a first input soundfield signal (402) originating from a first soundfield endpoint (120, 170) within a 2D or 3D conference scene (300) to be rendered to a listener (301) is described. The first input soundfield signal (402) is indicative of a soundfield captured by the first soundfield endpoint (120, 170). The conference multiplexer (110, 175, 210, 400) is configured to set up the conference scene (300) comprising a plurality of talker locations (321, 322, 332, 331) at different angles (323, 333) with respect to the listener (301); provide a first sector (325); wherein the first sector (325) has a first angular width (324); wherein the first angular width (324) is greater than zero; and transform the first input soundfield signal (402) into a first output soundfield signal (403), such that for the listener (301) the first output soundfield signal (403) appears to be emanating from one or more virtual talker locations (321, 322) within the first sector (325).
