I imagine a world where anyone with access to a set of headphones can experience surround sound as if they're sitting in a movie theater. My company takes surround mixes of movies and music, and converts the audio to binaural stereo using state-of-the-art personalized HRTFs. Just send in a few photographs of your head and ears, and we'll send you your own algorithm to turn multichannel audio into a virtual experience.
Aight, I'm gonna go watch a TED talk about an idea that's probably much better than my garbage. See ya Friday.
