YouTube user ChibiChn has come up with a complex but accurate method of transmitting sound using a laser beam. He uses some 555 chips and a small laser to transmit the sound using laser light. Then a photo transistor, a comparator and a audio amplifier are used to receive the laser light and convert it back into audio. The result is audio that is slightly lower than CD quality. There are much simpler methods of doing the same if high fidelity is not needed.
