The audio quality of the PS4 is noticibly poor. There is a rattle/distortion type sound whenever the music becomes even the slightest bit louder. The credits music in particular sounded more distorted than usual. It is diffucult to tell whether it affects the sound effects as well, but it is most noticeable with the music. I have not played the PC/PS3 version to tell if it is just a PS4 issue.
