DTS Revels in Multiple Strategies
What struck me about my DTS briefing is that the formidable licensor of surround standards has dual strategies in two areas. One is sound enhancement for portable devices. For high-end surround headphone use, there's Head Tracker, which causes the soundfield to follow your head movements -- just like in this pic of a dude turning his head. Head Tracker will be built into an Onkyo receiver. For lower-end portable uses, DTS offers Envelo, which deals with the problems of highly compressed audio formats. DTS's other dual strategy arrives with the acquisition of Neural Surround, a matrixed adaptation format, which overlaps a little on existing Neo:6 territory. But the DTS people say the two circuits will find different applications, with Neo:6 (again) as the high-end player and Neural focusing on low-bit-rate applications like broadcast and MP3 (it's already used in XM, or now Sirius XM, satellite radio). DTS will be among the surround licensors to offer height channels with Advanced Neo. It will adapt 7.1 sources to 10.2, 11.2, or 12.2 channels, and is now being discussed with a/v receiver makers.
