SRS TruSurround XT

TruSurround XT is the latest in the family of TruSurround Technologies. Based upon its patented predecessor and namesake, TruSurround XT also solves the problem of playing 5.1 multi-channel content over two speakers or headphones, but it goes further. TruSurround XT utilizes proprietary algorithms from SRS Labs combined with Dialog Clarity Enhancement and Trubass to provide listeners with a truely immersive audio experience. TruSurround XT is a combination of four distinct and patented processing techniques from SRS Labs:

As signals are processed with TruSurround XT, Dialog Clarity is applied first. TruSurround then rendersmulti-channel signals in such a way as to take advantage of the human hearing system and create anencompassing sound field. Once the two-channel output is generated, those channels are processed withTruBass.
Dialog Clarity - TruSurround XT includes an exciting new audio technique that acts much like a lens does for vision, bringing movie dialog into “focus” during the playback of any surround-encoded material such as DVD movies and satellite and cable television programs. Speech and center dialog becomes much clearer and crisper, making it easier to discern from today’s sophisticated movie effects.
TruBass - TruSurround XT uses SRS TruBass technology to create incredible cinema-like bass from all speaker types, including headphones. This patented technique, enhances bass performance using proprietary psychoacoustic techniques. By selectively boosting a series of low bass harmonics, TruBass restores the perception of low frequency tones, providing a deep, rich bass experience.
Incredible Stereo with WOW - TruSurround XT goes a step beyond the standard TruSurround technology by processing standard two-channel stereo material as well as multichannel encoded material. SRS WOW technology literally “WOWs!” anyone who hears it by creating a soundstage that spreads the image upward and all around, making this a incredibly dramatic improvement in the playback of any stereo audio over a two-speaker system.
TruSurround XT Headphone – This technology provides a surround sound listening experience over headphones. When listening to multichannel content such as DVD movies over headphones, the listening experience is fundamentally different than listening to speakers. Since the headphone speaker drivers are covering the outer ear, the listening experience differs greatly from traditional speaker playback. TruSurround XT uses patented headphone perspective curves to solve this problem and provides a non-fatiguing, immersive, home theater listening experience. TruSurround XT Headphone also delivers exceptional 3D audio from mono and stereo material.
