• Neo 6 technology allows various sound elements within a channel
or channels to be steered separately, and in a way which follows
naturally from the original presentation.
• Neo 6 offers a music mode to expand stereo nonmatrix recordings
into the five- or six-channel layout, in a way which does not diminish
the subtlety and integrity of the original stereo recording.
DTS-ES Extended Surround is a new multi-channel digital signal
format developed by Digital Theater Systems Inc. While offering high
compatibility with the conventional DTS Digital Surround format, DTS-
ES Extended Surround greatly improves the 360-degree surround
impression and space expression thanks to further expanded
surround signals. This format has been used professionally in movie
theaters since 1999.
In addition to the 5.1 surround channels (FL, FR, C, SL, SR and LFE),
DTS-ES Extended Surround also offers the SB (Surround Back)
channel for surround playback with a total of 6.1 channels. DTS-ES
Extended Surround includes two signal formats with different
surround signal recording methods, as DTS-ES Discrete 6.1 and DTS-
ES Matrix 6.1.

The stereo CD is a 16-bit medium with sampling at 44.1 kHz.
Professional audio has been 20- or 24-bit for some time, and there is
increasing interest in higher sampling rates both for recording and for
delivery into the home. Greater bit depths provide extended dynamic
range. Higher sampling rates allow wider frequency response and the
use of anti-alias and reconstruction filters with more favorable aural
characteristics.
DTS 96/24 allows for 5.1channel sound tracks to be encoded at a rate
of 96kHz/24bits on DVD-Video titles.
When DVD-video appeared, it became possible to deliver 24-bit, 96
kHz audio into the home, but only in two channels, and with serious
limitations on picture. This capability has had little use.
DVD-audio allows 96/24 in six channels, but a new player is needed,
and only analog outputs are provided, necessitating the use of the D/A
converters and analog electronics provided in the player.
DTS 96/24 offers the following:
1. Sound quality transparent to the original 96/24 master.
2. Full backward compatibility with all existing decoders. (Existing
decoders will output a 48 kHz signal)
3. No new player required: DTS 96/24 can be carried on DVD-video, or
in the video zone of DVD-audio, accessible to all DVD players.
4. 96/24 5.1-channel sound with full-quality full-motion video, for
music programs and motion picture soundtracks on DVD-video.
Dolby Digital identifies the use of Dolby Digital (AC-3) audio coding for
such consumer formats as DVD and DTV. As with film sound, Dolby
Digital can provide up to five full-range channels for left, center, and
right screen channels, independent left and right surround channels,
and a sixth ( ".1") channel for low-frequency effects.
Dolby Surround Pro Logic
II
is an improved matrix decoding
technology that provides better spatiality and directionality on Dolby
Surround program material; provides a convincing three-dimensional
soundfield on conventional stereo music recordings; and is ideally
suited to bring the surround experience to automotive sound. While
conventional surround programming is fully compatible with Dolby
Surround Pro Logic
II
decoders, soundtracks will be able to be
encoded specifically to take full advantage of Pro Logic
II
playback,
including separate left and right surround channels. (Such material is
also compatible with conventional Pro Logic decoders.)
Dolby Digital EX creates six full-bandwidth output channels from 5.1-
channel sources. This is done using a matrix decoder that derives
three surround channels from the two in the original recording. For
best results, Dolby Digital EX should be used with movies soundtracks
recorded with Dolby Digital Surround EX.

Circle Surround
II
(CS-
II
) is a powerful and versatile multi-channel
technology. CS-
II
is designed to enable up to 6.1 multi-channel
surround sound playback from mono, stereo, CS encoded sources
and other matrix encoded sources. In all cases the decoder extends it
into 6 channels of surround audio and a LFE/subwoofer signal. The
CS-
II
decoder creates a listening environment that places the listener
“inside” music performances and dramatically improves both hi-fi
audio conventional surround-encoded video material. CS-
II
provides
composite stereo rear channels to greatly improve separation and
image positioning – adding a heightened sense of realism to both
audio and A/V productions.
CS-
II
is packed with other useful feature like dialog clarity (SRS Dialog)
for movies and cinema-like bass enrichment (TruBass). CS-
II
can
enable the dialog to become clearer and more discernable in movies
and it enables the bass frequencies contained in the original
programming to more closely achieve low frequencies – overcoming the
low frequency limitations of the speakers by full octave.

HDCD
®
(High Definition Compatible Digital
®
) is a patented process for
delivering on Compact Disc the full richness and details of the original
microphone feed.
HDCD encoded CDs sound better because they are encoded with 20-
bits of real musical information as compared to 16-bits for all other CDs.
HDCD overcomes the limitation of the 16-bit CD format by using a
sophisticated system to encode the additional four bits onto the CD
while remaining completely compatible with the CD format.
When listening to HDCD recordings, you hear more dynamic range, a
focused 3-D sound stage, and extremely natural vocal and musical
timbre. With HDCD, you get the body, depth and emotion of the
original performance not a flat, digital imitation.
