Systems and methods for estimating audio at a requested location are presented. In one embodiment, the method includes receiving from a client device a request for audio at a requested location. The method further includes determining a location of a plurality of audio sensors, where the plurality of audio sensors are coupled to head-mounted devices in which a location of each of the plurality of audio sensors varies. The method further includes, based on the requested location and the location of the plurality of audio sensors, determining an ad hoc array of audio sensors, receiving audio sensed from audio sensors in the ad hoc array, and processing the audio sensed from audio sensors in the ad hoc array to produce an output substantially estimating audio at the requested location.
