SPL Analog Code® Plug-ins
While SPL hardware products have been fascinating audio professionals from home studio owners to mastering engineers in
the world’s most renowned facilities for years, the need for this
technology in the form of plug-ins has also been an ever-growing
demand. With the Analog Code® plug-ins we have finally accomplished our much desired goal: to transfer to the digital domain the
high quality we have striven to achieve with our analog processors
throughout several decades.
The first time we ever heard a software that fulfilled our expectations, one of our hardware developers said to the programmers:
“you have cracked the Analog Code” — thus was coined the name
of our digital products.
The Vitalizer
The Vitalizer applies psychoacoustic and audiometric principles
to achieve a verifiable improvement while enhancing the sound.
The Vitalizer processes only the original signal and generates no
artifacts. Patented filtering techniques highlight the richness of
the audio signal in all its detail, while the interactive parameters
make it possible to alter the sound in a musical and effective way.
This unique combination of precise filtering and intuitive usability
enable you to instantly make any music production more stimulating and natural. Music and speech are made clearly distinguishable and comprehensible, loudness more intense, and the whole
soundscape becomes wider.

Introduction
Music emphasizing technique
One of the Vitalizer’s main features is the unmasking of overlapping sounds. The way it works is, in principle, opposite to the way
compression formats (MP3, etc.) do: instead of deleting allegedly
unnecessary information, it enhances it. In order to do that, the
Vitalizer takes into account the perception of a frequency in relation to its volume. By shifting louder frequencies slightly in time,
softer and formerly overlapping sounds are “unmasked” and
made audible. The audible effect of unmasking could be described
in general terms as more clarity and depth in a mix. Lows sound
more powerful and better defined, mids more focused and differentiated and highs more vivid and brilliant. It can be used on
individual channels to emphasize the sound character of instruments or vocals. The clarity and definition achieved guarantee an
adequately perceptible presence in the mix.
Another characteristic of the Vitalizer’s sound optimization process is the adaptation of the sound spectrum to the non-linear
sensitivity of human hearing. This phenomenon was audiometrically proved in the 1930’s thanks to the equal loudness contours,
also known as the Fletcher-Munson curves after their discoverers.
According to these curves, the human ear is most sensitive to mid
frequencies, i.e. to the frequency range of speech. A s a result, frequencies below 200 Hz and above 6000 Hz need reinforcement
in order to achieve a well-balanced auditory impression – frequencies between 6 kHz and approximately 11 kHz are perceived
as being 5 dB softer, for example. The Vitalizer uses the equalloudness contours to balance the frequency spectrum according
to human hearing, which in turn improves loudness. As a result,
individual elements of a mix can sound more present without an
actual increase in level. At the same time, the sum signal also benefits from the Vitalizer processing since it can achieve the same
loudness with less sound pressure level.

Basics
Operation
Mono, stereo or multi-channel operation
The Vitalizer plug-in can be used either for mono or stereo operation. In stereo operation each control element governs both channels simultaneously. The Stereo Expander function is active for
stereo applications, whereas it is grayed out for mono applications
due to the fact that you cannot control stereo elements in mono
mode. This can help you identify immediately if you are using the
Vitalizer in stereo or mono mode. You can also use the Vitalizer
as a „Multi-Mono“ or multi-channel plug-in, as long as your host
program suppor ts this function.
Basics
The frequency spectrum is usually divided into three frequency
bands: highs, mids and lows, all of which are provided in the Vitalizer, even though, as opposed to conventional usage, low and mid
filter settings are interrelated. The high f requency control allows
processing of high frequencies and harmonics. You can adjust each
of the three f requency bands separately and control the intensity
of the process independently.
The low and mid filters share the same intensity control (PROCESS).
The fact that you can set the filters and the intensity independently
allows for many sound possibilities with only two controls: when
processing low signals you can choose between a deep, soft or dry
sound. In conjunction with the PROCESS control, strong amplification of low frequencies with a low intensity setting results in a
totally different sound than if you were to have low amplification
with high intensity. The connection to the mid filter is always given
by the PROCESS control. This means that you can optimize low and
mid frequencies jointly for the sake of psychoacoustic and audiometric relevance. For example, the mid frequency band, to which
the human hearing is specially sensitive, can be automatically
damped when you choose a SOFT setting.

Operation
Default Settings
The following are the default set tings of the plug-in and they have
no impact on the audio signal:
• DRIVE at “0” (center position)
• BASS at “0” (center position)
• COMPRESSION at OFF (hard left)
• MID-HI TUNE at 3 kHz (center position)
• PROCESS at OFF (hard left)
• LC-EQ at LOW (hard left)
• INTENSITY at OFF (hard lef t)
• STEREO E XPANDER at OFF (hard left)
• OUTPUT at “0” (center position)
First Steps
The instructions provided here are based on the default set tings
and are meant to help you get to know the Vitalizer.
1) Slowly turn up the PROCESS control. The intensity of all fre-

3) Start varying the MID-HI TUNE control. Turn it to the right and
4) Turn the LC-EQ control hard left (to LOW) and set INTENSITY to 10
5) As its name implies, STEREO EXPANDER expands the stereo
6) Use the ACTIVE control to make A/B comparisons between pro-
quencies above 3 kHz will increase (since MID-HI TUNE is set to
3 kHz). Set PROCESS to 10.
Turn it to the lef t and the lows sound soft and round. Choose a
sound character and level for the low end. You can compensate
any level fluctuations in the lows with the COMPRESSION control.

Active
Use the ACTIVE function to turn the Vitalizer on and off. The Vitalizer is on when the ACTIVE switch is on. The POWER switch is always
on and has no effect on the plug-in. When you open the plug-in,
the ACTIVE switch blinks for a couple of seconds before remaining permanently on. This is meant to indicate the tube warming
phase which takes place on the original hardware. The main purpose of the ACTIVE function is to allow A/B comparisons between
processed and unprocessed signals. We recommend to make such
comparisons regularly. The risk of overprocessing is higher in comparison to common processors given that the Vitalizer sounds ver y
pleasant. A/B comparisons are therefore indispensable to avoid
exaggerations. Furthermore, we also recommend the use of reference recordings.
Drive
The DRIVE control enables you to set the level at which
the Vitalizer fi lters operate. You can adjust fl uctuating
input levels to 0 dB or work with lower/higher levels
depending on the sound effect you want to achieve.
The level can be set between -20 dB and +6 dB. When
set to 0 dB (center position) the output level is equal
to the input level. With higher DRIVE settings you can
achieve extreme effects. If you work with a too low
DRIVE level you will not be able to achieve an adequate processing
intensit y, even with the PROCESS control set to its maximum - in
which case you will need to increase the DRIVE setting.

Control Elements
Bass
With the BASS control you can emphasize two different
sound colors in the low end. When set to the center position the signal is not processed. If you turn the BASS control to the left you will achieve a warmer and sof ter sound;
referred to as SOFT. This roundness is symbolized on the
left side of the control by circles that increase in size as
you turn further left. If you turn the BASS control to the
right you will achieve a drier and more percussive sound;
referred to as TIGHT. This tightness is symbolized on the right side
of the control by squares that increase in size as you turn fur ther
right. The BASS control is directly related to the PROCESS control.
The latter determines the amount of processed BASS signal mixed
with the original signal. As a consequence, you can obtain plenty
of completely distinct sounds: a hig h BA SS setting with a low PROCESS setting results in a totally different sound than a low BASS
setting with a high PROCESS set ting. You need only two controls
to enjoy a vast array of sound possibilities; all of which can be listened to and set in no time.
Compression
The Vitalizer features a compressor that af fects the
low f requency path of the processed signal exclusively.
Neither the low end of the original signal nor the mids
or highs are af fected. Thus, the COMPRESSION control
allows you to compensate level fl uctuations caused by
the proces si ng of low frequency signal s. Th e comp re ssor
is therefore a very important component in the optimization of the processing level. The GR (Gain Reduction) LED indicates
that the compressor is active. The compressor is a so-called “soft
knee” compressor with a smooth cur ve to achieve almost unnoticeable sound results. As you increase the COMPRESSION setting, the
compression ratio is increased while the attack threshold is lowered. In order to ease operation, additional parameters have been
preset so you only have to deal with one single knob.

Mid-Hi Tune
Use the MID-HI TUNE control to set the cut-off frequency.
Frequencies above this frequency are amplifi ed whereas
frequencies below are attenuated. The intensity is set
with the PROCESS control. The frequencies affected
range from 1.1 kHz ( hard right) to 22 kHz (hard left). Consequently, the sound becomes brighter the more you turn
the control to the right. From 1.5 kHz upwards, mid frequencies become more emphasized. The MID-HI TUNE
control allows you to tone down excessively br ig ht sounding material by setting it to somewhere around 10 kHz and combining it with
a very high PROCESS setting.
The MID-HI TUNE fi lter is not a static fi lter, unlike common EQ
fi lters, and therefore it cannot be operated like one. It is integrated
within a fi lter network and affects frequency and phase response
over a very broad frequency range. The setting never affects the
selected value exclusively. It focuses on a given point but spreads
throughout the whole f requency spectrum. Setting the MID-HI
TUNE requires more attention than set ting a simple graphic EQ:
you have to always listen to the sound as a whole. The advantage
is that, together with the BASS and PROCESS controls, you can
process signals to a signifi cant extent. As we mentioned before,
the Vitalizer is based on psychoacoustic and audiometric principles so all processing is aimed at optimizing your sound – faster
than with any other technique – to make it sound better.

Control Elements
Process
Both BASS and MID-HI TUNE work with two different signal paths: the original signal and the processed
signal, both of which are mixed together at the output.
The PROCESS control determines the amount of processed signal used, i.e. the intensity of the effect generated by the BASS and MID-HI TUNE fi lters. Furthermore,
the PROCE SS con trol al so determ ines the dampi ng inten-
sity of dominant mid frequencies (see the previous section). Dominant mid frequencies are reduced with higher PROCESS
settings. All frequencies below the cut-of f frequency selected with
the MID-HI TUNE control are affected.
LC-EQ
The high frequency fi lter is a broad band fi lter too and
can actually affect mid frequencies to add presence and
sharpness, specially to vocals. The frequencies affected
range from 2 kHz (hard left) to 20 kHz (hard right). The
INTENSITY control determines the intensity of the LC-EQ
(see the next section). The LC-EQ gets its name from the
hardware version’s high frequency fi lter, which is based
on a passive coil fi lter. Coil fi lters are inductive fi lters
and the symbol for inductance is “L”. The abbreviation for coil fi lter
is “LC” (where C stands for capacitor). This type of fi lters are well
known for their pleasant, sof t sound. Coil fi lters were standard components up to the 1960’s, when they were quickly replaced with the
advent of cheaper resistor-capacitor (RC) fi lters. The sound of classic “vintage” gear has a lot to do with the use of these components.
When programming the Vitalizer plug-in we payed special attention
to faithfully emulating the sound character of the original LC-EQ. The
LC-EQ can improve the brilliance of individual or sum signal s without
making them sound too sharp. No signal artifacts are created in the
proces s, as opp ose d to oth er hig h fre quenc y en hancement system s,
like the so-called exciters, in order to avoid ear fatigue. The Vitalizer
simply improves the sound structure of the original signal.

Intensity
The LC-EQ works with two dif ferent signal paths: the original signal and the processed signal, both of which are
mixed together at the output. Use the INTENSITY knob to
adjust the amount of LC-EQ effect mixed with the original
signal, i.e. the intensity of the ef fect. Due to their design
and broad frequency range, you can use the MID-HI TUNE
and LC-EQ fi lters as perfectly complementar y tools. For
example, if you use the MID-HI TUNE fi lter to generate a
notch in the mid frequencies and amplify the high frequencies from
5-8 kHz, vocals could lose presence, in which case you could use
the LC-EQ fi lter for the vocal frequency range and enhance it with
the INTENSITY control.

Stereo Expander
The STEREO EXPANDER function is meant to create the
impression of a wider stereo image. The space image
is improved by doubling signals originally placed left
or right in the stereo image, inverting their phase and
summing them with the opposite channel. This results
in a better perception of the original signals while
the stereo image seems to reach out of the speakers’
plane. Mono signals placed in the center of the stereo
image are diminished during the process. We recommend settings
between 6 and 14. For high settings, and depending on the nature
of the source signal, you should always check the mono compatibility of the signal with the help of a goniometer.
Output
The OUTPUT knob reduces or increases the output level.
The control ranges from -20 dB to +6 dB. The 0 dB mark
is set at the center position. Generally speaking, you will
need to reduce the level, considering that the Vitalizer
processing tends to increase it. If you set the input level
to 0 dB with the DRIVE control – which ought to be a good
starting point for fi ltering – there will undoubtedly be an
increase in level after the processing occurs.
IMPOR TA NT: Use the OUTPUT control to exploit the dynamic range
available, but try to avoid distortion. The OVL (Overload) LED next
to the OUTPUT control can be very useful at that. The OVL LED
indicates overloading is occurring at the plug-in’s output, which
can result in distortion. You should always avoid the OVL LED from
turning on. If it does, use the OUTPUT control to reduce the output
level until it turns off.

Settings
The four SETTINGS buttons allow you to
save all your settings with a simple mouse
click. The Vitalizer saves the current settings permanently. As soon as you click on
another SET TINGS button, the current settings are saved under the previously active
preset. For example: In the image shown
here, all parameters would be saved under
preset “B” if you were to click on another button.
Any previously saved preset can be recalled with a simple mouse
click on the corresponding button; you can then use or edit the
settings. If the host program allows it, the presets can also be
automated so you can use different set tings at different points.
As long as you work in a specifi c session of the host program and
the plug-in is installed, the settings are saved and can be recalled
afterwards. When opened, the plug-in loads the active preset settings instead of the default settings. If you remove the plug-in from
the host program all presets are lost. To erase all presets at once
you can remove the plug-in from the host program and then reinstall it.
