Corey Taylor explained the album title to Spin
magazine: "I love when a phrase has a few different meanings, and I was trying to find play on words for 'idiosyncrasy.' Idiosyncrasies are those little things that differentiate us, that make us individuals. But at the same time they tie us together. I hit on 'audio secrecy' and immediately realized that it can mean something completely different to people. It can mean something dark or practical, light or funny. After thinking about it for a while, I realized it's a descriptive way of talking about music. Consider classic songs like 'Master of Puppets
' by Metallica or 'These Arms of Mine
' by Otis Redding. They're drastically different songs, yet both epic songs. Why do they sound the way they do? Why do people gravitate towards them? To me it's about the undertones or the overtones, the details—the way it was recorded, the temperature in the room, the instruments they used, the performance, the mixing and the mastering. It all comes down to these little elements. That, to me, is audio secrecy. That's what makes one song killer and one song filler. What makes one song live forever and the other one delegated to a bargain bin."
