1. A method of performing sound source localization, comprising: calculating a frame amplitude difference vector based on short time frame data acquired through an array of microphones, the frame amplitude difference vector reflecting differences between amplitudes captured by microphones of the array during recording the short time frame data; evaluating similarity between the frame amplitude difference vector and each of a plurality of reference frame amplitude difference vectors, each of the plurality of reference frame amplitude difference vectors reflecting differences between amplitudes captured by microphones of the array during recording sound from one of a plurality of candidate locations; estimating a desired location of sound source based at least on the candidate locations and associated similarity.
