What is Audio

Audio refers to sound that is transmitted, recorded, or reproduced in a way that can be heard by the human ear. It encompasses everything from natural sounds in the environment to speech, music, and digitally created effects. At its core, audio is the perception of vibrations that travel through a medium, usually air, in the form of sound waves. These vibrations are then captured by our ears and interpreted by the brain, allowing us to experience communication, entertainment, and the world around us in a meaningful way.
