    Abstract: A WFS(Wave Field Synthesis) reproduction method and an apparatus thereof are provided to utilize sound image localization information of a sound source extracted from a 5.1 channel signal or a stereo as a WFS input data. A WFS(Wave Field Synthesis) reproduction apparatus comprises an audio format channel signal input part(101), a BSS(Blind Source Separation) processing part(102), a power panning operation part(103), and a WFS rendering part(104). An audio signal according to a channel is inputted to the audio format channel signal input part. The BSS processing part extracts an object audio signal by pairing two channel signals among the audio signals. The power panning operation part obtains sound image localization information with the extracted object audio signal. The WFS rendering part outputs a driving signal to a loudspeaker array.

    Abstract: An apparatus and a method for reproducing a surround sound field for reproducing reflection provide presence and a space sense to a listener by reproducing the reflection by a panning scheme or reproducing corresponding reflection by using respective loudspeaker. The information for reproducing the reflection is inputted to an input unit(810). A signal processor(820) selects the loudspeaker for applying the panning mode based on the information for reproducing the reflection and produces a refection signal. A signal processing unit(830) localizes the produced reflection signal to a virtual sound image according to the panning mode. A reproducing unit(840) reproduces the localized reflection signal through the selected loudspeaker.
