Abstract: A method of outputting audio in a teleconferencing environment includes receiving audio streams, processing the audio streams according to information regarding effective spatial positions, and outputting, by at least three speakers arranged in more than one dimension, the audio streams having been processed. The information regarding the plurality of effective spatial positions corresponds to a perceived spatial scene that extends beyond the speakers in at least two dimensions. In this manner, participants in the teleconference perceive the audio from the remote participants as originating at different positions in the teleconference room.

Abstract: The present document relates to setting up and managing two-dimensional or three-dimensional scenes for audio conferences. A conference controller (111, 175) configured to place an upstream audio signal (123, 173) associated with a conference participant within a 2D or 3D conference scene to be rendered to a listener (211) is described. An X-point conference scene with X different spatial talker locations (212) is set up within the conference scene, wherein the X talker locations (212) are positioned within a cone around a midline (215) in front of a head of the listener (211). A generatrix (216) of the cone and the midline (215) form an angle which is smaller than or equal to a pre-determined maximum cone angle. The upstream audio signal (123, 173) is assigned to one of the talker locations (212) and metadata identifying the assigned talker location (212) are generated, thus enabling a spatialized audio signal.

Abstract: A system and method of matching reverberation in teleconferencing environments. When the two ends of a conversation are in environments with differing reverberations, the method filters the reverberation so that when both signals are output at the near end (e.g., the audio signal from the far end and the sidetone from the near end), the reverberations match. In this manner, the user does not perceive an annoying difference in reverberations, and the user experience is improved.

Abstract: From a plurality of received voice signals, a signal interval in which there is a talker collision between at least a first and a second voice signal is detected. A processor receives a positive detection result and processes, in response to this, at least one of the voice signals with the aim of making it perceptually distinguishable. A mixer mixes the voice signals to supply an output signal, wherein the processed signal(s) replaces the corresponding received signals. In example embodiments, signal content is shifted away from the talker collision in frequency or in time. The invention may be useful in a conferencing system.
