Hi,
I noticed that the audio quality of spoken dialogues are sometimes afflicted with notable compressions artifacts.
It really destroys the atmosphere sometimes. Skyrim had this too, but much much worse.
This issue was observed by owners of the german (me), italian and spanish version so far:
forums.gamesas DOT com/topic/1545372-spanish-audio-issue/
reddit DOT com/r/PS4/comments/3s9535/fallout_4_ps4_issue_audio_localization_quality_is/
Please think about releasing a optional (e.g.: as dlc) HD encoded audio pack for the localized versions!
EDIT:
I put some examples of this poor audio qualtiy together (links are with timestamp, just copy & paste and it will direct you to the example position):
