Abstract
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.
