What those sounds will be and what will reproduce them is still up for discovery. I'm interested in a system for sound sources that goes beyond sample playback and gives us acoustic modeling and and other kinds of real-time synthesis. The project has probably more computer power than any other theater in the world. Essentially, there's an application that lives on the Onyx. There's a piece of memory called shared memory, and in there are all the attributes of where the viewer angle is.
Any application can pull that information.
There's another application that's running the sound corollary, which is looking at the camera position and calculating what in the sound objects database is in the range of hearing off-screen that requires cueing up that sound. That sends a signal over the network to a dedicated computer that's managing loading and playback of sounds. The message is being sent to the computer running Macs or other MIDI software, which translates coarse messages into MIDI messages and handles fadeup and fadeout. So they've done the Universe. There are a lot of space phenomena that are great because they see things from the Hubble, flat images, but because of time they can figure out the model and create volumetric renderings.
