Selected Third-Party Audio Processing and Sound Enhancement Algorithms for the TASxxxx Audio Processors NOTE: Not all algorithms are available on all TASxxxx audio processors. Contact TI for the availability of specific algorithms. The following list of algorithms represents a sample of those that are available on TI's TASxxxx audio processors at any one time.

SRS 3D® Natural 3D stereo sound for two-speaker systems. Audio enhancement suite containing SRS 3D stereo and TruBass™ Wow™ psychoacoustic bass enhancement technology. Patented bass enhancement technology which provides up to an octave of TruBass lower bass frequency perception from speakers or headphones. Creates a virtual experience from up to 5.1 multichannel, sur- SRS® Labs, Inc. TruSurround™ round encoded, or stereo source material played over any stereo-speaker or headphone playback system. Creates a virtual surround sound experience from up to 6.1 multichannel, surround encoded, stereo or mono source material played over any stereo- TruSurround XT™ speaker or headphone playback system. Includes additional audio enhance- ments of dialog clarity and TruBass bass enhancement technology. Provides improved comprehension of actor’s dialog in DVD movies and other Dialog Clarity video programming. Elevates sound image; compensates for poorly placed speakers by elevating Focus™ the sound image to the optimal location. Creates “virtual speakers” and reproduces spatially correct, multi-channel ® QSound® Labs, Inc. QSurround output on two-channel equipment. Enhances sound reproduction on five- and six-channel systems. Creates multi-channel audio from any stereo source by automatically QMSS™ “steering” acoustic images to multiple speakers. Qxpander™ Enhances stereo sound for either headphones or speakers.
