Audio generally means any equipment used to play or record sound. Additionally, sensing sound is one of human instinct. Music, human voices, breeze blowing through the grass, and conversations are all sound. On the other hand, sound related to technological devices are called audio. For instance, the sounds of the television, the telephone, or the music played by the CD player are all called audio.
As a result, if you are a stereo acoustic or a headphone lover, or if your occupation is related to sound or audio, “.audio” might be the very domain you are searching for!
