Positioning-

Digital entertainment into the home is more pervasive than ever. However, many consumers prefer to use the built-in speakers in their televisions, do not have six or more speaker home theater systems, or do not want the bulk associated with a discrete subwoofer. This is especially true for a second or third television located in a bedroom or den. Two speaker audio systems are subject to the frequency
range limitations of small speakers and that presents a challenge in reproducing impressive low frequency effects critical to the DVD experience. This is especially true with flat panel plasma or LCD designs, with thin form factors. Two speaker home audio systems do not have a sub-woofer and many generic virtual surround algorithms ignore the separate sub-woofer channel.

Product Overview

Spatializer VirtuaLFE™ delivers the kind of heart-pounding low frequency effect normally delivered by a discrete powered sub-woofer speaker. The technology is fully scaleable to take advantage of the “.1” (low frequency effects or LFE) channel, as well as the frequency response capabilities of the speakers in use. Spatializer VirtuaLFE expands the feature set and utility of consumer electronics products and further differentiates these products from the competition.

How It Works

Spatializer VirtuaLFE™ processes the sub-woofer channel with proprietary psycho-acoustic techniques to virtualize, reinforce and enhance the effect for accurate reproduction through two speaker home audio or on-board television speakers. The result is an emotive low frequency effect that brings DVDs alive as if an actual sub-woofer speaker were employed. The efficient algorithm architecture makes implementation feasible on a wide array of home entertainment products.

Spatializer Advantage

With its core technology initially developed for the recording studio, Spatializer Audio Laboratories offers a variety of digital audio solutions. Spatializer products offer a wide and deep sound stage that is true to the original mix, with no unwanted coloration. Spatializer technology widens the soundstage in the way the sound engineer intended by keeping the vocals firmly centered, but adding depth and dimensionality, while maintaining the relative position of the wide-panned ambient effects or instruments. Competitive solutions are less true to the source material, blur the center images or add other unpleasant sonic artifacts. Spatializer technologies also help deliver high definition audio through reinforcement and enhancement of the frequency spectrum, improve Internet audio, eliminate static noise and deliver maximum performance from speakers or headphones.
