    Hi,

    Wondering if Sound (like music, voice) can be placed on light waves and be projected out as light waves not as sound waves?

    depends on what you mean

    If you mean like a visualizer with 3D dimensions based on the frequencies, and amplitudes, yes

    Transmitted via light waves to another device? Absolutely

    Actually create the sound? not in any way that we can do at this point no.
