Abstract
Provided is an apparatus and method for reproducing a wave field using a loudspeaker array. A loudspeaker array may be configured in front of and behind a listener, and a wave field synthesis rendering and a three-dimensional sound image localization rendering may be performed based on a position of a sound source.
Claims20
An apparatus for reproducing a wave field, comprising:
- a sound source position analysis unit to determine a position of a sound source by analyzing sound image localization information;
- a rendering unit to output a wave field synthesis signal by performing a wave field synthesis rendering for the sound source based on the determined position of the sound source;
- and
- a plurality of loudspeakers to reproduce the wave field synthesis signal and to be arranged in two front rows.
