Around the room, with a 3 dB pan law as the sound travels between the speakers; Left, Center, Right, Right Surround, Left Surround, then back to Left, then a jump to the LFE. The Surrounds are 3dB lower at 21.5, and the LFE plays twice as long as the others.

All done with the new SMPTE Digital Pink Noise algorithm.

(But not done in a SMPTE Compliant Package.)
