Audio transmission refers to the process of sending sound signals from one location to another. This can be achieved through various methods, including wired connections like cables and wireless technologies such as radio waves or Bluetooth. The sound is converted into electrical signals, which are then transmitted and converted back into sound at the receiving end. In modern communication, audio transmission is essential for applications like telephony, broadcasting, and streaming services. It allows people to communicate over long distances, share music, and enjoy podcasts. The quality of audio transmission can be affected by factors like bandwidth and interference.
