The numbers 666 appear in DOOM’s soundtrack in a spectrogram?

I´m (Robin Ek, TGG) quite sure that the most of you had no idea (whatsoever) that you can find the numbers "666" in a spectrogram, in Mick Gordon´s "Doom 2016´s" soundtrack. Well, it seems to be true. As people have been able to get the spectrogram to show up in Adobe Audition.
