Thats what we've analyzed it for. We found some structures that could contain a code. But without audio analysis? I'm not sure. Maybe the purrs and houls-soundbits are the sound of stellar objects. But that would be even harder to decode. If it points - for example - to a star system with a special star and 5-7 planets, that would be even harder. Or what kind of information could we gather, if we know "this is the sound of a Y Class star"?
It's also not really logical. Why should an enemy race like the thargoids send out a artifact that points the way to their home system? Do they want to have a little chat?

We KNOW that they can talk our language. It would be logical to assume that they just would send an spoken message, no such purr and howling stuff.
When we analyse it visually we see that it emits gas and small objects(spores?). We see that it's organic technology, something the thargoids and their "friendlier" brothers use(Oresrians). I personally would not wonder if it emits some counter-measure-mycoid to the mycoid developed by INRA, that forced the thargoids out of our part of space.
But accustical? I had no sound back in the day of frontier: elite 2. Are there any similarities to the thargoids?
To be honest i have no good feeling about the matter. The UO have been scanned and analysed for month. Now they tell us "it's much simpler". I would not wonder at all if it turns out, that there was nothing to it. Just some kind of countdown or something. I would be very sorry for all the people wo have invested so much work without any hint or guidance by E: D.
