Trouble is no apparent repeat that anyone has seen.
I did a bunch of experiments this morning, recording multiple pieces of barnacle audio from login for 5 minutes.
The idea being, if it's a cycle, a login to solo should initiate the start of the cycle each time so the result should be consistent.
Each piece of audio had a different high/low pattern.
It doesn't prove anything but I think the priority has to be to find a pattern.
It's like the UA purrs all over again, the purrs were never decoded and I think it's generally assumed they are just pseudo-random.
I suppose given the case of the UA perhaps we should ignore the obvious (purrs for UA, and high low purrs for barnacles) and bear in mind, as per the UA, there may be another signal in there.
I tried slowing the "crunch" right down, it kinda seems there might be short/long signals in there but I'm doubtful, there wasn't many potential signals/crunch and if they are they seem like they'd be very hard to decode.
