APPARATUS FOR CREATING A VERTICAL DIRECTION VIRTUAL CHANNEL CAPABLE OF GENERATING THE VERTICAL DIRECTION VIRTUAL CHANNEL SIGNAL OUTPUTTED TO A VERTICAL VIRTUAL SPEAKER AND A METHOD THEREOF

摘要

PURPOSE: An apparatus for creating a vertical direction virtual channel and a method thereof are provided to generate the vertical direction virtual channel signal outputted to a vertical virtual speaker using only a horizontal loudspeaker.;CONSTITUTION: An apparatus for creating a vertical direction virtual channel(200) comprises a vertical direction spectrum application part(210) and a vertical virtual speaker signal generator(220). The vertical direction spectrum application part applies a vertical spectrum shape to a source signal. The vertical direction spectrum application part is input with a left side source signal and a right side source signal belonging to a top layer. The vertical direction spectrum application part applies a vertical spectrum shape to the left side source signal and the right side source signal.;COPYRIGHT KIPO 2012
