Audio

Audio refers to sound, especially when recorded, transmitted, or reproduced. It encompasses the range of audible frequencies and can include music, speech, and ambient sounds. In technology, audio pertains to the electronic reproduction of sound through various means, such as speakers or headphones, and involves both hardware (like microphones and sound cards) and software (like audio editing programs). Audio is integral to many forms of media, including television, film, radio, and online content, facilitating communication and entertainment. It can be mono (single channel) or stereo (two channels), and advanced formats include surround sound and high-resolution audio. The study and manipulation of audio signals fall under the domain of acoustics and audio engineering.
