Claim:
1. A wearable device comprising: a microphone array comprising two or more microphones positioned some distance from one another, wherein each of said microphones is adapted to convert acoustic signals into electrical signals; a directional audio stream generator (DASG) adapted to convert electric signals output by one or more of said microphones into a first direction specific audio signal corresponding to acoustic signals having a first direction of arrival; and an Optical Tracking System (OTS) comprising an optical sensor with a field of view directed towards a front of said wearable device and optical information processing circuits to process optical information acquired by said optical sensor, said OTS adapted to: (a) identify at least one optically detectable feature of a sound source within the field of view of said sensor, (b) estimate a relative direction of the sound source, and (c) generate at least one direction parameter used by said DASG to generate the first direction specific audio signal.
