A sound test is a function built into the options screen of many video games. This function was originally meant to test whether the game’s music and sounds would function correctly, as well as giving the player the ability to compare samples played in Monaural, Stereophonic and later Surround sound. In modern times, most sound tests function mostly as a jukebox to listen to the game’s music, sound effects, and voice tracks for enjoyment.
