Trinnov Audio, designer and manufacturer of
reference audio processors for home theaters, high-end hi-fi, professional audio, and
commercial cinemas, is pleased to announce the release of software version 4.2.16, an
upgrade for the Altitude 32 and Altitude 16 processors that incorporates a much-desired but
previously unavailable feature: an Object Viewer for Dolby Atmos™. While enjoying Atmos
content, Altitude owners will be able to use the processor’s user interface to see a graphic
three-dimensional representation of the location of each sound object, all in real-time.
The Object Viewer is available on the 3D Speaker Layout and Configuration screen of the
Altitude GUI. Reading the spatial information encoded on the source, the Viewer shows
each sound object as a sphere overlaid on a graphic representation of the listener’s room.
Each object moves or remains in a fixed position, as determined by the sound mixer
during the final home soundtrack mix. This screen also displays the speaker
configuration of the system, with each speaker shown as a cube. A Meter function
changes the color intensity of each speaker according to its sound level, with an option to
hide the speakers to more easily view the objects. A Pause function allows the user to
freeze the screen display for closer analysis.
“We are very happy to deliver to Trinnov owners a highly useful and even educational
feature that will enable them to better discover the details of the Dolby Atmos mix of their
favorite films and music,” said Trinnov CEO Arnaud Laborie. “Our customers have shown a
great deal of interest in the process of creating Dolby Atmos soundtracks and
understanding how sounds are located in playback. Our Object Viewer allows them, for the
first time, to see into the audio mix and to identify to what extent the sound mixer has
utilized the 3D sound palette provided by Atmos. Our research and development team
works tirelessly to ensure that Trinnov remains at the leading edge in delivering innovative
capabilities and technologies to our customers.”
Support for a new HDMI board
In addition, this software release includes support for a new HDMI 2.0 board produced by
its new manufacturing partner, Cypress Technology of Taiwan.
Trinnov has now begun shipping Altitude 16 and Altitude 32 processors with a new HDMI 2.0
board. The new software optimizes the interface to this new board while working equally
well with all previous versions of the Trinnov HDMI board. Functionally, this new board is
essentially identical to the previous generation HDMI board but with an additional eighth
HDMI input and ARC/eARC capability.
Impulse Generator for Time Alignment
For advanced calibrators seeking to perform custom time alignment of individual
speakers and subwoofers, a “Pulse” function has been added for each speaker, located
on the Processor/Input page of the GUI. It generates a short, positive pulse at -10 dB full
scale. By carefully listening to this signal reproduced by more than one speaker, the
calibrator can adjust individual delays in increments of .1 milliseconds to align the
speakers. In particular, this function can be highly useful in fine-tuning subwoofers to
match the main speakers.
Speaker Manufacturer PEQ Settings
Speaker manufacturers often require electronic parametric equalization filters for specific
models, typically required for bi-, tri-, or quad-amplified speakers. Altitude processors can
now import these settings, eliminating the need for calibrators to enter filter parameters
manually for each speaker. Once these settings are downloaded from a USB key, they
become available through an alphabetized pull-down menu located on the 3D Speaker
Layout and Configuration page of the Altitude GUI. Multiple speaker manufacturers are
now making these settings available for use on the Altitude platform.
In addition, on the 3D Speaker Layout and Configuration page, the PEQ button will be
highlighted in blue for any/all channels where filters have been applied.
Graphic Equalizers Set to ISO standards
Graphic equalizers have always been available for each channel on the Processor page of
the Altitude GUI. For 4.2.16, the frequency scale for the Graphic EQ faders has been
extended down to 10 Hz while still meeting the ISO standard for ?-octave center
frequencies. The additional faders, bringing the total to 34, are provided for 16, 12, and 10
As before, due to Trinnov’s unique software platform, all Altitude 32 and Altitude 16
processors, regardless of the age of the processor, can be upgraded to 4.2.16 through a
simple ten-minute download. This update is available to all owners at no cost.
