Soundscape Announces Dolby Surround Encoder/Decoder
Plug-In
 June 7, 1999 Soundscape Digital Technology was
showing the Dolby Surround Encoder/Decoder Plug-in for Soundscape Digital Audio
Workstations and the Soundscape Mixtreme PCI Card at the NAB Convention in Las
Vegas and the AES Show in Munich. The plug-in is the result of collaboration between
Dolby Labs and Soundscape Digital Technology and licenses Dolby's DSP code, developed
for the Motorola 56301 DSP used in the Soundscape V2 Mixer environment.
The
plug-in includes a separate 4-channel-to-stereo encoder and a stereo-to-4-channel
decoder. The Soundscape V2 Mixer has also received enhancements for surround mixing
and now includes new elements for Surround channel strips and Surround Panners.
These can be placed as required in the mixer and the complete configuration saved
to a mixer file, which can be loaded instantly.
The Dolby Surround Encoder/Decoder Plug-in is available exclusively from Soundscape
Digital Technology's International Distributors and Dealers. Both Encoder and
Decoder plug-ins can run on one DSP in the Soundscape V2 Mixer environment, both
for Soundscape DAWs and the Mixtreme
PCI card.
About Dolby Surround
Dolby Surround is a phase-matrix encode/decode process that makes it possible
for regular stereo program sources to carry four channels of information. Originally
developed as a sound-with-picture format, the channels are configured with three
across the front (Left, Center, Right) and a fourth (Surround) reproduced by
speakers to the sides and rear of the listening area.
Because Dolby Surround soundtracks are specially encoded during production
and then decoded on playback, producers can control the placement and movement
of sounds in a way that creates a realistic listening experience. Dolby Surround
soundtracks also create a wider, more enveloping soundfield even when played in
normal stereo.
With tens of millions of playback systems in homes worldwide and a multitude
of encoded films and TV programs available to the consumer Dolby Surround has
become the standard for high-quality surround audio.
System Requirements
Soundscape DAW with V2.04 software or Soundscape Mixtreme PCI Card with V1.05
software. Surround Channel Strips and Panners provided as standard with these
versions.
Specifications
Four-channel Dolby Surround encoding/decoding. Adjustable surround delay, 10ms
- 100ms. Band-limited pink noise calibration system included. Four-way automatable
surround panners are included with the Soundscape DAW V2.04 software and the
Mixtreme V1.05 software.
Overall frequency response: 20 Hz-20 kHz (L, C, and R inputs) 100 Hz-7 kHz
(Surround input)
With millions of home theater and multimedia systems equipped for Dolby Surround
playback, the demand for surround-encoded programming is skyrocketing. Thanks
to the Dolby Surround Encoder/Decoder plug-in, you can now produce Dolby Surround
mixes for videos, TV shows, ad spots, multimedia, CDs and video games entirely
within a Soundscape DAW or Mixtreme environment.
The Dolby Surround Encoder/Decoder makes surround mixing far more efficient
for the Soundscape DAW or Mixtreme user. D-to-A and A-to-D conversions are no
longer needed, and the Dolby Surround encoding and decoding processes match
those of the industry standard Dolby Model SEU4 and SDU4 units.
