Device, system, and method of source separation, Blind Source Separation (BSS), signal processing, enhancement of acoustic signals, and reduction of noise from acoustic signals. A first acoustic microphone captures a first acoustic signal at a first location. A second acoustic microphone captures a second acoustic signal at a second location. An optical microphone or laser microphone, that targets or aims towards the first location and not towards the second location, captures an optical feedback signal. One or more correlator units, and one or more de-correlator units, perform particular correlation operations and de-correlation operations, among the first acoustic signal, the second acoustic signal, and the optical feedback signal; and produce, separately, a cleaned or reduced-noise version of the first acoustic signal, as well as a cleaned or reduced-noise version of the second acoustic signal. Optionally, two or more optical microphones or laser microphones are used, to achieve further improved Blind Source Separation. |
