Abstract
A sound reproducing apparatus for providing an optimal virtual sound source and a sound reproducing method therefor are provided. The sound reproducing apparatus includes a virtual sound signal generation unit for generating more than one virtual sound signal corresponding to locations and the number of target virtual sound sources on the basis of more than one inputted sound signal, and a virtual sound signal downmix unit for downmixing said more than one virtual sound signal to virtual sound signal outputs corresponding to a predetermined number of output channels. The number and locations of diversely variable virtual sound sources are provided, thereby obtaining an effect of providing an optimal virtual sound source adaptively depending on each different environment.
