Audio
Audio (Latin = I hear) is used as a component of words that have to do with hearing or sound engineering.
Audio refers to the human auditory range, which refers to the sound wave range from 18 Hz (the flicker limit) to 20 kHz.
Audio events generally belong to the noises, which means in particular all spoken languages ??and music.
With the popularization of music systems, the term audio became common as an abbreviation for audio system. Audio is mainly used to differentiate pure music and sound applications from image and film applications (e.g. video, home cinema).
