发明名称 Programmable audio mixer
摘要 Audio mixes for a plurality of conference locations are controllably obtained by using a matrix multiplication arrangement. The audio mixes for the individual conference locations are obtained by multiplying a dynamically determined gain matrix by an audio input matrix. Coefficient values in the gain matrix are dependent on whether incoming and outgoing transmission paths are assigned to a location and on whether an audio sample is being received or not.
