DTS 96/24

DTS 96/24 is a digital audio format enabling high sound quality

playback in 5.1-channels with a sampling frequency of 96 kHz and 24

bit quantization on DVD-Video.

Manufactured under license under U.S. Patent #’s: 5,451,942;

5,956,674; 5,974,380; 5,978,762; 6,226,616; 6,487,535; 7,212,872;

7,333,929; 7,392,195; 7,272,567 & other U.S. and worldwide patents

issued & pending. DTS is a registered trademark and the DTS logos,

Symbol, DTS-HD and DTS-HD Master Audio are trademarks of DTS,

DTS Express

DTS Express is an audio format supporting low bit rates (max. 5.1-

channels, 24 to 256 kbps).

Audyssey MultEQ

Audyssey MultEQ XT is a room equalization solution that calibrates any

audio system so that it can achieve optimum performance for every

listener in a large listening area. Based on several room measurements,

MultEQ XT calculates an equalization solution that corrects for both

time and frequency response problems in the listening area and also

performs a fully automated surround system setup.

Audyssey Dynamic EQ™

Audyssey Dynamic EQ solves the problem of deteriorating sound

quality as volume is decreased by taking into account human

perception and room acoustics. Audyssey Dynamic EQ works in

tandem with Audyssey MultEQ XT to provide well-balanced sound for

every listener at any volume level.

Audyssey Dynamic Volume™

Audyssey Dynamic Volume solves the problem of large variations in

volume level between television programs, commercials, and between

the soft and loud passages of movies.

Audyssey Dynamic EQ is integrated into Dynamic Volume so that as

the playback volume is adjusted automatically, the perceived bass

response, tonal balance, surround impression, and dialog clarity

remain the same.

Audyssey

Audyssey Dynamic Surround Expansion™ (DSX)

Realistic reproduction of sound relies on the ability of audio systems

to match human hearing performance. Three key requirements are:

(i) frequency response; (2) dynamic range; and (3) accurate spatial

reproduction. The requirements for frequency response have already

been surpassed with sampling rates that exceed human hearing. The

dynamic range limits of human perception have also been met with

current digital audio systems operating capable of signal to noise ratios

that approach 120 dB. Accurate spatial sound rendering, however, has

not yet reached the limits of perception as human perception relies on

the combination of sounds arriving from many more directions than

what 5.1 surround sound systems provide. Audyssey DSX technology

was developed to overcome the spatial sound rendering limitations

faced by 5.1 surround sound formats.

The ITU 5.1 channel standard recommends three front loudspeakers

and two rear loudspeakers. The Left (L) and Right (R) front

loudspeakers should be placed at ±30° relative to the central listening

position. The Center (C) loudspeaker should be at 0° and the surround

loudspeakers (SL, SR) should be placed between 100° and 120°. All

loudspeakers must be equidistant from the center listening position or

compensated with time delay if that is not possible. A separate low-

frequency effects (LFE) channel is used to reproduce additional bass

content from the subwoofer.

There are certain things that 5.1 surround sound systems do well

compared to 2-channel stereo. For example, it is possible to move

sounds across the front seamlessly. It is also possible to create

ambience behind the listener. But 5.1 channel surround systems do not

provide enough channels from which to render the required reﬂected

sound components for a seamless and enveloping soundstage.

Unfortunately, the additional two back surround channels in 7.1

systems are not in the right place to provide a signiﬁcant perceptual

improvement.

Adding more channels to a surround system is not for special

effects. Accurate spatial sound reproduction requires rendering of

directional sound cues and non-directional ambient cues. Reﬂections

arriving after the direct sound play a critical role in the perception of

soundstage width and depth. To have the most impact, additional

surround channels should be used to control the direction, time of

arrival, and frequency response of the reﬂected sound to render an

expanded soundstage that reproduces sound with better localization

and envelopment than what 5.1 systems provide.

Information

DTS Surround

DTS Digital Surround

DTS Digital Surround is the standard digital surround format of DTS,

Inc., compatible with a sampling frequency of 44.1 or 48 kHz and up

to 5.1-channels of digital discrete surround sound.

DTS-ES™ Discrete 6.1

DTS-ES™ Discrete 6.1 is a 6.1-channel discrete digital audio format

adding a surround back (SB) channel to the DTS digital surround

sound.

Decoding of conventional 5.1-channel audio signals is also possible

according to the decoder.

DTS-ES™ Matrix 6.1

DTS-ES™ Matrix 6.1 is a 6.1-channel discrete digital audio format

inserting a surround back (SB) channel to the DTS digital surround

sound through matrix encoding. Decoding of conventional 5.1-channel

audio signals is also possible according to the decoder.

DTS-HD High Resolution Audio

DTS-HD High Resolution Audio is an improved version of the

conventional DTS, DTS-ES and DTS 96/24 signals formats, compatible

with sampling frequencies of 96 or 48 kHz and up to 7.1-channels

of discrete digital sound. High data bit rate performance provides

high quality sound. This format is fully compatible with conventional

products, including conventional DTS digital surround 5.1-channel

data.

DTS-HD Master Audio

DTS-HD Master Audio is DTS, Inc’s lossless audio format compatible

with up to 96 kHz/7.1-channels. The lossless audio coding technology

faithfully reproduces the sound of the studio master. It is fully

compatible with conventional products, including conventional DTS

digital surround 5.1-channel data.

DTS NEO:6™ Surround

DTS NEO:6™ is a matrix decoding technology for achieving 6.1-

channel surround playback with 2-channel sources. It includes “DTS

NEO:6 Cinema” suited for playing movies and “DTS NEO:6 Music”

suited for playing music.
