PROBLEM TO BE SOLVED: To provide a method for determining an adequate measurement window for sound source localization in echo environments. SOLUTION: The method for sound source localization comprises the steps of computing an envelope (120) of a signal (110); performing a non-linear, onset preserving smoothing of the envelope (120); and evaluating cues for sound source localization, using the measurement points (140, 150, 160) where the smoothing changes from its rising phase to its falling phase.
