Sound Test is an option that appears in the Super Smash Bros. games.
The Sound Test allows the player to listen to most of the music and sounds in the game. Players can listen to the voices of characters, stage music, and listen to other variety of sounds. In Super Smash Bros. and Melee, the Sound Test can be accessed through Data Mode; in Brawl, it can be accessed through either Data or Option Mode; in SSB4 it is located in the Vault and can also be accessed via the sound settings in Options. If the player leaves the Sound Test while a song is playing and goes back through the menus, the song will still play until it is overridden by another piece of music, or until the player enters the character select screen.
Some pieces of music are unavailable in the Sound Test for unknown reasons; this includes the Fighter Select music in SSB, the Giga Bowser music in Melee, and the Cruel Brawl theme along with the winter version of Obstacle Course in Brawl. SSB4's Sound Test is missing some character voice clips, such as those of Duck Hunt.
In Super Smash Bros. for Nintendo 3DS, the Sounds section can be set to play music even when the Nintendo 3DS is in sleep mode, with the L and R buttons used to skip between tracks, though the player can only hear the song play if they have headphones.
There are occasions where the Sound Test has sound clips that were never used in-game:
