Sound localization in the presence of multiple reflections using a binaurally integrated cross-correlation/auto-correlation mechanism
A precedence effect model is described that can use a binaural signal to robustly localize a sound source in the presence of multiple reflections for the frontal horizontal plane. The model also estimates a room impulse response from a running binaural signal and determines the spatial locations and...
