Next Generation
Audio for Broadcast
By Anthony Wilkins, International Sales Manager
and Head of Marketing, J√ľnger Audio...

T

he world of broadcast audio is on
the verge of a major revolution.
Numerous "3D Immersive" formats are
under development and will find their
way into the mainstream of broadcast
production and distribution in the near
future. Unlike the world of channel
based coding as we are accustomed
to, these new formats will support
more channels and/or object based
audio coding. For the end consumer,
there will be two major benefits from
this new approach, a greater sense
of involvement or immersion, and a
degree of personalisation.
Greater involvement will come from
an increased channel count typically
by the addition of overhead "height"
channels. This creates a "3D" sound
image where the viewer or listener is
immersed in audio in all dimensions.

Object based audio will
give the user the option
to
personalise
their
experience by selecting
from a number of audio
sources, and controlling
the level and maybe even
the position in the mix.
In object based audio,
an "object" is essentially
an audio stream with
accompanying descriptive
metadata. The metadata carries
information about where the object
is in the mix and at what level, and is
used to render the audio experience
for the end user. Objects may be
static and placed at a fixed point in
the mix, or dynamic where they are
panned across the three dimensional
soundscape.

Revolution: 3D immersive sound

Does this mean multiple speakers
need to be installed to avail of these
new benefits? Not necessarily, although of course the best experience
will result from a full installation of
discrete speakers at both floor level
and overhead, however where this is
not practical, the final "renderer" will

re-create the mix as accurately as possible based on the actual number and
location of speakers the end user has.
An increasing number of soundbars
that are designed to sit underneath a
display are already available to create
a surround experience without consuming valuable space.
What does this all mean for the
broadcaster? A complete re-build
of existing facilities and a total rethink about the audio processing
equipment required for outside
broadcast vehicles? Well, if we get it
right, it should entail just relatively
minimal changes to overall workflow
and
hardware,
but
inevitably
some additions to production and
distribution equipment. In the case
of object based audio, the metadata
appropriate for the final codec needs
to be created and added to the audio
for distribution, and the engineer
needs to be able to monitor this
complex mix (and all the potential
downmix variations) to ensure that
the distribution chain is fed with all
available objects correctly. Loudness
levels should also be considered in
respect of existing standards and
there should be provision for local
insertion of content at any point in the
chain.
