So, how does it work then? I won't say it is simply a matter of hooking up an electro-optical sensor to a telescope and pointing it at a light bulb, but that's the meat and potatoes of the sub $1,000 (800) hardware hack at least. Fluctuations in air pressure on the surface of the hanging bulb are created by the sound of conversation, or music, and make a hanging bulb vibrate. An analog-to-digital converter makes the conversion from electrical to digital information. The researchers have developed an algorithm for the attack method, which they named Lamphone, that can "recover sound from the optical measurements obtained from the vibrations of a light bulb." This is done passively and without needing to be in the same room. When it comes to human speech, the researchers used Google Cloud Speech to transcribe the conversation, and the music was correctly identified using Shazam and SoundHound.
