Based on its principal as seen here.

Hmm. I don't understand how that would work, under the CD section, that is. He says that the quadraphonic information on Compact Disks is stored at (lol) about 30 kHz, when we all know that CD's are only technically capable of doing 22.05 kHz (Nyquist Theorem at it's simplest), but due to its inefficiencies (from when a wave starts in relation to the sampling), its more like divide by 2.2 instead of 2 to determine the "maximum" useful frequency response (without aliasing). In other words the maximum truly usable frequency that is consistent would be at about a little higher than 20 kHz.
