RE: The Solarium - An Alternate Reality Game in Space
"Polyph____"
I believe that, since you are working with an audio file, it might have something to do with polyphony.
"THEXWORLDXHASXCHANGEDZSEEKXTHEXSTARSZ"
Ok, so there are either the letters "X" and "Z" between each word. Without them it spells "The world has changed seek the stars". That's kinda obvious. But the order of the X's and Z's is "XXXZXXZ".
What I'm thinking is that this could be the key of a vigenere cipher? Or, seeing as it's Z and X, maybe coordinates?
"The bradbury II business computer"
The main text visible is "The bradbury II business computer".
But you can also see "...sman on the go", "...can do for [you]", and ...n do for... (probably a repeat of can do for you). I don't know what this is referencing but I believe it is something within the game... these quotes might be familiar to you?
"No Gods In The Abyss"
I don't know about this one really...
The audio itself:
Hmm, this might actually be very distorted morse code. I'm not sure about it though. It also sounds like it could be translated to an image, a lot of images sound like that when translated...
I'm not very good with this arg stuff so i hope this was (slightly) helpful lol
Sorry for taking so long to get to you!

Regarding "THEXWORLDXHASXCHANGEDZSEEKXTHEXSTARSZ" The X's and Z's are actually artifacts from the decoding process. It was encoded using an enigma cipher, and those letters were used instead of spaces in order to separate the words.
However, it is odd that both X and Z were used rather than just one or the other. That's definitely suspicious and we will investigate it further.
I should've elaborated about bradbury. Bradbury is effectively an in-game AI that was deactivated for some reason. It uses old magnetic tapes that are scattered throughout the game for storage. We're still missing some tapes, so we think this image has some sort of location hidden in it somehow.
But now that I think about it, bradbury is a huge machine, so I'm not sure how a businessman on the go could use it...
Maybe there's a portable version somewhere?
We've got no clue about the gods in the abyss thing either.
We've tried to convert the sound to an image via SSTV, but there may be other ways we don't know of.
