Bioshock Infinite Burial at Sea Ep. 2 Audio Trivia

[Some-creep]

Fun fact, if you unpack the audio files for Bioshock Infinite, you can listen to all of them individually (obviously). If this is done with Burial at Sea Ep. 2, however, you'll run across a file called "sfx_evt_inf_alley_loop_01". It sounds like nothing more than creepy ambient music, but if reversed and sped up 150% as shown below, it's actually an altered clip of Sally being burned at the end of the first episode.
