At the GDC 2009, DTS Inc. unveils to developers their new DTS Neural Surround Sound technology that enables games to present real-time 7.1 soundtracks on the Wii, Xbox 360, and PS3 via PC.
By using existing technology built into the systems, DTS Neural Surround is able to convert the 5.1 signal into a true 7.1 surround experience.
Whether the signal is digital or analog, DTS Neural Surround is able to convert the sound into rich, fully immersive 7.1 channel surround sound. Now, when gamers hear something creeping up behind them, the sound will really be there.

A Prototype on Xbox 360 will be the first title released using DTS Neural Surround; however games using the DTS Neural Surround technology are currently under development for all platforms.
