Weirdness: Inside's Soundtrack was Created Using a Human Skull

What the heck? According to a very detailed and informative article over on Gamasutra, brilliant PlayStation 4 indie Inside's soundtrack was created using an actual human skull. No, you read that right - composer and sound designer Martin Stig used a real human skull and jawbone to help make the game's music.

"Early on, as we were working on Inside, I had the idea of working with a human skull because I think it's very interesting how the sound of your own voice sounds very different in your own head," Stig writes. This particular author knows exactly what he means; that geordie accent sounds 100 times thicker when it's played back.

Stig continues: "So I had the basic idea of trying to recreate sounds as they would sound if they were happening inside your head. That was the curious thought that led me to acquire a human skull and experiment with it. In the end, the sounds I played through the skull were actually synthesized sounds, which I usually don't do a lot - most of the work I do is done by going and recording things with a microphone. But for Inside, I think because of the game's aesthetics, I kind of felt it should be associated with '80s B-movie soundtracks - cheap yet cool soundtracks."

"When I played them through a skull, the sounds acquired another quality. I did some post-processing as well, of course, but even without it you can hear this kind of timbre, which inspire a very nuanced association with a synth soundtrack," he explains.

"The end result, after the post-processing, is generally a bit creepy and cold. The sound has almost a chill about it. Eventually all the teeth fell out of the skull because of the vibrations, but while they were still there they created this small vibrating sound that I think was unsettling but also strangely familiar to people. Because we all know it, in a way." Now that's pretty grim, but we won't deny that it's also incredibly interesting.

We're big fans of Inside here at Push Square, and to be honest, this macabre realisation makes the whole thing seem even more fascinating. But what do you make of this? What did you think of the game's soundtrack to begin with? Don't try this at home in the comments section below.
