Provided are sound field reproducing apparatus and method. The sound field reproducing apparatus includes an input unit for receiving reflection reproducing information, a signal processor for selecting loudspeakers and calculating reflection signal for applying a panning algorithm based on the reflection reproducing information, a signal treatment unit for localizing the calculated reflection signal on a virtual sound image according to the panning algorithm; and a reproducer for reproducing the localized reflection signals through the selected loudspeakers.

Provided are an apparatus and a method for reproducing a surround wave field using wave field synthesis. The apparatus includes an audio signal analyzer for analyzing a received multi-channel audio signal to check the number of audio signal channels, and extracting a sound source signal for each checked channel from the multi-channel audio signal; a wave field synthesis renderer for localizing the extracted sound source signal for each channel at a virtual sound image outside a narrow space using wave field synthesis so that the extracted sound source signal is suitable for the number of the checked audio signal channels; and an audio reproducer for reproducing the localized virtual sound source signal.
