First I would like to say that I personally have speant many, many, many hours on vessel, only to start over from scratch just to solve it in just 30 minutes.
Just for a quick review, the vessel clip with the voice in it occurs at 3:03 - 3:06, and is kindof an echoing voice.
Using the techniques achieved from the Capital G song, where we inverted the 1 song and we got "Wreckage is pain", I simply took a very similar synth (to be specific, the one right after the words.), and inverted it, and had to line it up witht he original synth. Now i did not do this perfectly, but It made the voice alot clearer. I then did a quick noise removal, high and low pass filtered it, used the fft filter, and then normalized it.
After listening to it over I was hearing... "___ct _____ic" and I thought the second word started with a P, such as Perfect. After listening to it more, I made the second word out to Patriotic, and the first to.... you guessed it... Act.
Now people who have listened to say that now they can hear it in the original song as well as my filtered version, and some say that it fits the bill, but it isnt concrete enough to say that its 100% what the voice is saying.
You might not agree with me, but as of right now, this is pretty much the only explanation we have for Actpatriotic, and unfortunatly, the site was taken down due to us brute forcing it via IP adresses. Maybe now since we found the actual source of it, 42 would be kind to put it back up for us.
BTW in most of the song samples I accidently cropped of the full pronounced "C" at the end of patriotic. You can hear it almost being said, but i cut it from the original sound file early on. If you want to hear it in its entirity, do it yourself.
Anyway: Works
