1. A method, comprising:
receiving sound signals with at least a local microphone array of a device, wherein the sound signals comprise at least one target sound;
generating an a priori estimate of the at least one target sound in the received sound signals, wherein the a priori estimate is based at least on a predetermined location of a source of the at least one target sound;
generating a direct estimate of the at least one target sound in the received sound signals, wherein the direct estimate is based at least on a real-time estimate of a location of a source of the at least one target sound; and
generating a weighted combination of the a priori estimate and the direct estimate, wherein the weighted combination is an integrated estimate of the target sound.
