Data over sound

Data over sound is a method of transmitting digital information using sound waves. Instead of using traditional wired or wireless signals, information is encoded into audio signals—like beeps or tones—that can travel through air or other mediums. Devices can send and receive these sound signals to exchange data, often with the help of specialized algorithms that convert data into sound patterns and back. This technology enables communication in environments where radio signals are limited or not practical, such as underwater or in areas with radio interference, making it a versatile option for short-range, secure, or covert data transfer.
