The Use of Dynamic EQ to Ensure
Consistency of Vocal Tone
Jünger Audio's Spectral Signature ensures that inconsistencies
in the spoken voice don't alter "station sound"...

T

here are many situations where it
is desirable to make sure that the
tonal, or spectral balance of a person's
voice remains absolutely consistent
from day to day, or session to session.
Think of a TV continuity announcer or
a radio presenter, their voice should
always be instantly recognizable, and

Spectral Signature user interface

should be a source of familiarity to
viewers and/or listeners. It's one of the
ways of maintaining audience loyalty,
which is especially critical these days
when there is so much content and so
many media platforms to choose from.
We're all human, and although as
adults, our voices have developed
their
own
characteristics
that
separate
us from others,
several
factors
can
influence
how we sound at
different times.
The effects may
be subtle, but
such things as
being
tired,
having a cold,
or the particular
environment we
are in, can change

our voice tone, slightly.
Throughout the broadcast chain,
there may be existing digital audio
processors in place for one reason
or another, be they parametric EQ's,
levelers, or multi-band compressors,
etc. They are presumably in place for
a good reason but will invariably treat
all signals presented in the same way,
irrespective of whether the spectral
structure is changing over time.
In the broadcast situation outlined
above, it is desirable to have a system
of EQ that can compensate for the
variations in vocal spectral balance, in
a way that does not require constant
manual intervention. This can be
achieved by using a dynamic equaliser
technique, such as Jünger Audio's,
newly introduced, Spectral Signature.
The principle is that, firstly, a section
of "ideal" dialogue is used to capture
the spectral response curve. This can
be achieved by a learning process

built into any Jünger products that
support Spectral Signature. Once
captured, the response curve, or
"sonic footprint", is stored as a preset
for future re-call. Multiple presets can
be stored depending on how many
voices will be in use at the particular
facility. After enablement and opening
of the appropriate preset, the actual
spoken voice is compared in real-time
to the stored reference curve. Over
13 individual frequency bands, gain
or attenuation is applied selectively,
when required to match the measured
spectral curve to that of the reference
preset.
Once set up and running, the process
is extremely transparent and works in
the background to make sure that any
inconsistencies in the spoken voice do
not create any changes or disturbances
to the "station sound".

like the D*AP4 VAP Edition and D*AP8

effectively with voice and dialogue
processing in your broadcast chain,
