Rebuscando,googleando y otros etceteras me he encontrado con esto
The English sountrack is also available in Logic 7 surround,a proprietary suite of surround algorithms designed to derive multi channel audio from two track media. Up to now the technology was mainly used in high end cars such as BMW and Rolls Royce. So if you should feel the urge to watch The Deer Hunter in your E-class or 7 Series, you're all set. The actual mix seems a little heavy on the center channel, with the rear speakers addding ambience. Still, the sound has been restored and there's no audible tape hiss or unnecessary new sound effects added to fill in the surround track.
Es decir, que más que para los Harman Kardon o incluso Lexicon, está mayormente incorporado en coches de alta gama, como la serie 760 de BMW (a partir de 125.000 euros) y Rolls Royce !!!!! ( a partir de noséni cuantos euros)
Me parese que se me va a hacer un poco difisi tener Logic7 en el coche )
