A visible light audio system is operable to enable free space optical communication of audio signals via transmission of modulated light intensity at a light source to a photo diode being operably engaged with a demodulator and audio output device. Embodiments of the present disclosure enable a plurality of visible light transmitting apparatuses being installed in a commercial or residential dwelling and operably engaged over a network to combine their microphone inputs via spatial, amplitude, spectral, and/or temporal filtering and physical and geometrical modeling methods to separate one or more acoustic sources using a visible light audio system comprising an array of light sources being operable to receive an audio source input.
