Doc Starz, a mathematician and former Microsoft software engineer from Edmonton, created them under his company Sound of Stars. Using a huge database of research from the alternative and contemporary health scene, he created mathematical maps of the different states of the brain and applied them to an algorithm, which spat out the frequencies. His catalogue mostly deals with healing and eliminating negativity. That’s how the idea came of using it at parties. I gave it to a friend, DJ Noor, just to experiment with his own creativity, but then it led to the idea of us experimenting with audiences.
