In video gaming, a sound room or sound test is a function built in to a game to allow the player to play the game's music tracks or sound effects at their whim. Traditionally, as the name suggested, the purpose of a sound test was for developers to test whether a game's sound and music were correctly functioning, and for consumers to test the performance of the game's sound on their hardware, acting as a way to easily compare the output in different modes of sound. As gaming developed, the sound test functionality largely evolved into a jukebox feature intended primarily, if not solely, as a reward for the player.
In the Fire Emblem series, the first known Sound Room was implemented in Fire Emblem: Thracia 776; it is possible that earlier games do or did at one time feature a hidden sound test function as part of the developer's debug tools, as in EarthBound, but none have ever been discovered. The Sound Room is traditionally unlocked upon first completing the game in question, though some games vary the unlock conditions. A common feature of Fire Emblem sound rooms, absent only in The Sacred Stones, is for it to also display the game's CG images and to allow the player to browse through them while listening to the game's music. Most Fire Emblem sound rooms contain the full game soundtrack, but on some occasions there are songs not accessible through the Sound Room at all.
