Audio Basics. Audio Signals. Sound is vibration. It is created by the movement of a sound source. It travels through air (or another medium) by the movement of air molecules. It is captured with a receiver (a microphone or our ears) by the movement of a diaphragm. Sound is a signal because there is information in these vibrations.
