Satellite subcarrier audio

Satellite subcarrier audio is a way of sending sound from one place to another using satellites in outer space. This can help us hear things from far away places and also send our own voices and sound to those same places.

It works like this: First, sound is converted into electronic signals. Then, those signals are sent up to outer space to a satellite. Once the satellite receives the signals, it converts them back into sound, and sends them back down to Earth.
