Based on the suggestion on
You can hear it if for exapmple you are in the Oochorrs and target the system the anomaly is comming from as a reference. Look right at the anomaly and open FSS. I get the cleanest audio, i think, at a 1/3 of the frequencies.
I ran it through Audacity, i could not see anything usefull in a spectrogram, but on 2x speed the anomaly sounds like what i think are normal Thargoid sounds. Im not an Audio engineer so i wouldn't know what else to do.
Anybody got more ideas?
