Patent number: 8315407Abstract: The present invention relates to an apparatus and method for localizing a sound source in real time. The apparatus for localizing a sound source in real time includes a sound signal acquisition unit for acquiring sound signals through two or more channels. A sample delay storage unit stores a plurality of pieces of data, sampled from the sound signals acquired through respective channels, for a predetermined period of time. A correlation calculation unit calculates correlations between the channels from the plurality of pieces of sampled data stored in the sample delay storage unit. A sound source direction calculation unit calculates an azimuth angle of the sound source using both the correlations between the channels and location relationships of the sound signal acquisition unit. Accordingly, the present invention can localize a sound source in real time.Type: GrantFiled: July 2, 2009Date of Patent: November 20, 2012Assignee: Sungkyunkwan University Foundation for Corporate CollaborationInventors: Wook Jae Jeon, Seung Hun Jin, Dong Kyun Kim, Jong Suk Choi, Chang Hoon Lee, Mun Sang Kim
