There may be a voice in the Ancient artifact transmission. Here's how I found it:
Tools: Audacity
Sample used - Digiscream's audio
http://www.digitalscream.org.uk/audio/unknown_artifact_audio.mp3
Method:
1) cut off the in-game audio (cargo scoop) at the end of the sample
2) Normalised remaining sample to 0DB
3) Pitch shift up by two oactaves
4) using audactity, I duplicated a portion of the background hum, and used this as a sample in the "Noise reduction" tool. The same effect may be done better by using a band pass filter. This was a quick and dirty attempt, with a little time we can clear this up a lot.
5) And here's the result:
CAUTION: turn down your volume

There is human voice after each burst of whale song. It sounds like a numbers station.
Someone with better audio skill than I should be able to process the audio with more clarity. This was inspired by the recent reddit post, which may not have been a hoax after all
Edit: Here's the reddit post that inspired the attempt effort. I was attempting to see if this post was a hoax or not:
