发明名称 Audio directionality control for a multi-display switched video conferencing system
摘要 In one embodiment, a method includes setting a target value for each audio source received from a plurality of remote participants to a telepresence conference, the gain coefficient array feeding a mixer associated with a loudspeaker associated with a display. A gain increment value is then set for each audio source, the gain increment value being equal to a difference between the target value and a current gain coefficient, the difference being divided by N, where N is an integer greater than one that represents a number of increments. Then, for each audio source, and for each of N iterations, the gain increment value is added to a current gain coefficient to produce a new current gain coefficient that is loaded into the mixer, such that after the N iterations the new current gain coefficient is equal to the target value. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
