Abstract
A three-dimensional sound reproducing apparatus is configured by cascading a sound field effect adding unit and a crosstalk canceling unit. The sound field effect adding unit adds a predetermined three-dimensional sound field effect to an input audio signal, thereby generating audio signals respectively corresponding to left and right channels. The crosstalk canceling unit performs a calculation process on the audio signals of the two channels so that, when the audio signals are respectively generated by two loudspeakers positioned in front of a listener, the audio signals reach the left and right ears of the listener without producing crosstalk. The resulting audio signals are supplied to the loudspeakers, respectively. A sound image localizing unit receives two-channel audio signals which are obtained by encoding a center-channel audio signal, a left-channel audio signal, a right-channel audio signal, and a nonlocalization audio signal, and outputs two-channel audio signals in which sound images are to be respectively localized at virtual loudspeakers.
