Optical sound

Optical sound refers to a method of transmitting audio signals using light, typically through a fiber optic cable or special discs like CDs and DVDs. In this process, sound information is converted into light signals that travel quickly and with minimal loss over long distances. At the receiving end, these light signals are converted back into electrical signals to produce sound. This technology allows for high-quality, noise-resistant audio transmission, making it ideal for digital audio systems, telecommunications, and media storage where clarity and fidelity are important.
