Audio diaries are the main narrative device of the BioShock series. They were recorded by the citizens of Rapture, either as notes for themselves or as messages for other residents. When the player picks up an audio diary, he or she can usually choose to play its message.
BioShock Infinite's downloadable content, Burial at Sea - Episode 1, features 17 audio diaries which can be now found dated by their previous users. Collecting them all is required to unlock the "Audio Enthusiast" Achievement/Trophy.
