DOOM Soundtrack Contains Hidden Message From the Devil?

We've all heard the rumours, play certain heavy metal and rock albums backwards to get a message from the devil. Well, the soundtrack in DOOM (2016) does something similar. It's not backwards masking however but spectrograph manipulation, a technique in which the waveform of a sound is reshaped. Those weird sounds in the track Cyberdemon from the game's soundtrack aren't just there to be unsettling, if you view the song in a spectrograph, they form pentagrams, and the number 666. To see how it looks, check out the YouTube video above from user FaceLikeTheSun, who confirmed its existence.

This isn't the first technical demonic easter egg from the series. Since the early days of TCP/IP, the port number 666 has been reserved for playing DOOM over a LAN, and in fact, that port number still retains such designation to this day. It's also not the first time an artist has hidden something under the spectrogram, EDM artist Aphex Twin famously hid his own face in one of his songs.
