Someone on reddit posted all the audio files related to the Unknown Artifact. https://www.reddit.com/r/UnknownArtefact/comments/3gira3/stripping_game_files_for_ua_sound/
Most of them mechanical chirping. Some are insectoid chirping or clicking. Some are the whale. Nothing we haven't heard before. Listened to all 102 files and nothing sounded significantly interesting. File 101 is a little weird but that's it.
Those are rips. Reverse engineering is frowned upon by FD and that's that.
All it tells us is that there are samples that the game plays in a predetermined sequence depending on (fill in the blank).
