Well... I was working on trying to isolate the vocals in Ockem's Razor. I wasn't exactly successful, but I did manage to do quite the opposite. I'm not that great at working with sound or anything, but this was done in Audacity. EDIT: The same treatment seems to have little effect on The Green Force.

Now I wonder if there is some way to "subtract" this track from the full one, leaving only the vocals? Anyone know how this can be done, like I said I don't know much about audio.

There's a nice tutorial on the Audacity Wiki about that:
http://audacityteam.org/wiki/index.php?title=Vocal_Removal
I've used both the inverted track method and the Center Pan Remover to achieve this on some tracks. This should work on Ockem's Razor, but as you've noticed the audio is not exactly center panned on The Green Force. On that song the vocals seem to be both flanged a bit and oscillated, so they represent a 'moving target' which is nearly impossible to isolate.

I processed Ockem's Razor with a tool called Transcribe! in an attempt to clarify some of the Cookie Monster vocals. I didn't have much luck, but by raising the pitch of the track one octave without increasing the speed, some words are more audible. FWIW, the "chorus", such as it is, seems to include chanting of the word "Possibility" or maybe "Possibilities" several times. I certainly couldn't extract any clever narratives about battling physicists or whatever.

It is, generally speaking, impossible to isolate vocal frequencies, because of instruments occupying the same frequency range. I'm not certain that the lyrics are important. I think the web address being parked is a hint. I think this is supposed to look like a band, but not be a band, in the game. I am feeling that The Glass Helmets is Teddy's dead drop area. He probably has an email @theglasshelmets.com. He can't make it to a meeting next week. He's been rumbled. Well. It fits my sensibilities, at least. Ha-Ha.

There hasn't been much thought on the Quote "Terror of the North"

Polar bears are known as that. So is the Snowy Owl.

The Bismarck was known as the terror of the north sea.

Angles. My body hurts from shoveling.

bismarck, snowyowl, thegreenforce, teddy, th, tgh, tidowave, bot, thebot, the.bot, the_bot, tido, tidow, ogre, irukandji, tanner, thecause, the.cause,
the_cause and, sadly, dumbo at theglasshelmets.com all failed.

They didn't pass the relay, so there isn't a catch all set up.

That Wiki is pretty much the exact method I used to remove the vocals... Is there no way to isolate the vocals with this, perhaps by "subtracting" to instrumental track I made from the original?

And yea, that's what I noticed with The Green Force... why would the two songs be recorded differently? Is it possible they want us to be able to isolate the vocals in one, but not the other?

Basically to do that you are supposed to 'invert' the procedure, I know I've read a more specific tutorial that explained exactly how that's done - but I don't remember off hand where. I haven't grabbed the MP3 off of MySpace, I may just do that to see if I can do it myself.

I would expect they'd recorded them differently, else you'd be able to extract the vocals or instrumentals in exactly the same way with both songs. I doubt it's was intended to be any 'clue', I think it's just incidental to the kind of sound they wanted to achieve. The oscillation of the voice (like it's spinning around you) moves it off the center pan and thus makes it nearly impossible to extract simply.

The extraction method we are talking about isn't about just clipping off the frequencies where vocals occur. It uses a difference between channels to extract either what is or isn't shared between them. Vocals tend to be 'center panned', which means they are present in both channels so they appear to come from the center of the stereo image. By defining what's common between the left and right channels and subtracting it, you can subtract the vocals. By defining what's different between the two channels, you can subtract the bulk of the instruments. The main artifact of this basic method is that bass tends to be center panned, so most of it is lost if you remove what's center panned. This whole method and idea is how karaoke music is often generated, especially machines made to strip vocals basically on the fly.

I find the myspace display picture quite enigmatic. At first I thought it could perhaps be a detail of a deconstructed building like those of F. Gehry, but when you watch in detail you realize it can't belong to a building. I turned, flipped and examined it from every angle and I arrived to the conclusion that it is a pile of curved tin.

It could perhaps be a shot from a modern art sculpture or the job of a photographer interested in industrial manufacturing. But I tend to believe in the first thing because the pieces are unequal and seem to be carefully placed.

In any case it would be interesting to know if there's any software able to track down a photography using its file structure or pixelation. I heard about a software used by the police to find images with illegal contents, so perhaps there's something similar for public use.

At first when i saw it i thought of the steel tables you can find in restaurant kitchens....Its the same

I'd be the cause or Tidowave it'd be good to have someone working in fine-super rich restaurants and contaminate the food or change recipes as a statement...

I see what you mean, but those tables are in one piece, while in the picture we can appreciate different pieces, that makes them quite different.

I know its one piece but to me the myspace pic is a clever collage for most parts....

can someone sumarise what they've discovered by ripping apart the glass helmets tracks/track? I'm becoming quie confused and want to know if the glass helments are relevant to the game.
