The soundtrack for the new Doom game includes satanic messages that are hidden in the sounds.

When run through special tools, the sounds for the game create an image of a pentagram and the number 666, sleuths have found.

The new game is full of surprises and hard-to-discover Easter eggs. Though most of them are found within the game itself, the newly-discovered audio shows that they are lurking outside its world as well.

What appears when the track 'Cyberdemon' is run through a spectogram

The find was made by a fan posting under the name TomButcher. They ran one of the tracks on the soundtrack – known as ‘Cyberdemon’ through a spectrogram, which visualises the frequencies found in a piece of audio.

He found the images hidden in the sound, in what appears to be a nod to Doom’s setting of Hell as well as another way of scandalising the many people who disapprove of the game.

The sinister images were already teased by the game’s composer, Mick Gordon, in a behind the scenes video. There may be more images in other tracks.

Including images in audio isn’t a new thing – perhaps the most famous is a creepy image of Aphex Twin’s Richard James that’s hidden in the song known as ‘[Equation]’.

The technique was even used in a viral video that captivated the internet last year. The sound in that footage included horrifying images and a message reading “YOU ARE ALREADY DEAD”.

It’s possible to turn any image into sound using software. Most pictures and to create a scratching metallic sound.
