An apparatus and method to localize multiple sound sources is provided. Virtual microphone signals are generated based on actual microphone signals from a microphone array including a plurality of microphones, which are arranged at intervals that may minimize space aliasing at a given sampling frequency, and sound source directions are tracked using the actual microphone signals and the virtual microphone signals. Thus, without increasing the aperture length of the microphone array, it is possible to achieve almost the same resolution as when a microphone array having a relatively long length is used. |
