Method and apparatus for sound sources localization with improved secondary sources localization

摘要

A method for localizing a plurality of signal sources (101, 102, fig 1), each source emitting a signal (106) forming together a combination of signals being received by a plurality of microphones (103,104,105), wherein the method comprises: Obtaining first approximate localization values of the sources from the combination of signals received by each microphone (4.1); Sorting the located source based on the dominance of the signal they emit; Identifying a dominant source and secondary sources; Removing at least part of the dominant source contribution from the received combinations of signals (4.4); and Obtaining a second approximate localization values of the secondary sources on the received signal without the contribution of the dominant source (output sources location 4.9).
