    Abstract: A method of elevation rendering an audio signal includes receiving multichannel signals including a height input channel signal of a predetermined elevation angle, obtaining first elevation rendering parameters for a height input channel signal of a standard elevation angle, obtaining a delayed height input channel signal by applying a predetermined delay to a height input channel signal, updating the first elevation rendering parameters based on the predetermined elevation angle, obtaining second elevation rendering parameters based on the label of the height input channel signal and labels of two output channel signals, and elevation rendering the multichannel signals and the delayed height input channel signal to output a plurality of output channel signals of an elevated sound image, based on the updated first elevation rendering parameters and the second elevation rendering parameters.

    Abstract: An apparatus and method of reproducing a virtual sound of two channels which adaptively reproduces a 2-channel stereo sound signal reproduced through a recording medium such as DVD, CD, or MP3 player etc., based on a listener's position. The method includes sensing a listener's position and recognizing distance and angle information about the listener's position, determining output gain values and delay values of two speakers based on the distance and angle information about the sensed listener's position and selecting localization filter coefficients in a predetermined table, and updating filter coefficients of a localization filter based on the selected localization filter coefficients and adjusting output levels and time delays of the two speakers from the determined gain values and delay values.
