UpMix User Manual
Introduction
The DaySequerra UpMix renders any two channel audio source (stereo, matrix encoded stereo or LtRt)
as surround sound. Because UpMix renders sound independently of the transport environment, it will
compliment analog, digital, linear or compressed mediums. Using the DTS Neural Audio process,
UpMix can simultaneously position individual elements within a rich surround field creating unparalleled
image stability and realistic granularity. This approach avoids taking “artistic license” with content by
placing audio exactly where it would be heard in a professional LEDE (Live End Dead End) listening
environment. For example, mono or pan-pot stereo will image in front of the listener on the center
channel, where stereo containing depth information will surround the listener using the full capabilities
of their surround decoder.
UpMix can be used as a stand-alone unit to monitor stereo production or in tandem with the
DaySequerra DownMix as a complete 5.1 transport solution. Surround content that has been encoded
by UpMix will be reproduced just as it was heard in the original 5.1 mix. To improve system reliability
and up-time, UpMix uses a robust DSP-based processing platform rather than the PC-based approach
to completely avoid broadcast disruptions caused by operating system lockups.
Operational Diagram
The diagram below shows an UpMix taking a two channel audio source, such as stereo, matrix
encoded stereo or LtRt, and creating a 5.1 channel surround mix using the proprietary DTS Neural
Audio process.
The surround mix produced from the input content is fully immersive to the listener when played
through a 5.1 monitor system.
Typical Applications
Here are some examples that describe some typical applications where you might use UpMix.
RADIO PRODUCTION STUDIO – UpMix allows production engineers to render mono or stereo content
into surround. The mix can then be broadcasted on a compatible medium. When used in conjunction
with DownMix, UpMix will allow the engineer to render a watermarked (Lw/Rw) two channel audio
source back into its original surround content.
STEREO TELEVISION MASTER CONTROL – Another application of UpMix is in a stereo television
master control room setup. UpMix allows rendering of original mono or stereo content into surround.
The surround mix can then be sent to an encoder and later combined video to have a complete HD
broadcast.
