Heartfelt congratulations!
Honestly—would you believe that kind of spin? You see—that’s precisely
my problem. How can I explain that WizooVerb is for real?
Let’s take it from the top: A year ago our developers cajoled me into attending the presentation of a “groundbreaking new reverb algorithm.”
My curiosity was negligible; my doubts weren’t: Does the world really need
another reverb? And if so, was the world begging for Wizoo, a no-name in
this field, to bring it to the table? In the face of such stiff competition and
rivals with legendary reputations? And even if the reverb was awesome—
who would believe us?
That was a year ago. Now the WizooVerb is here. So, what, you may ask,
prompted this about-face?
Well, firstly the reverb’s sound at that initial presentation was a jaw-dropping revelation! Not “promising” or “ok for starters,” not “less tinny” or
“denser than others”; it was simply a stupendous sensation in 3D sound.
No effect to be heard, only wonderful lifelike spatiality.
Though we were off to a very good start, we were unwilling to play it safe
and rest on these laurels.
We a spent a few more months with our noses firmly pressed to the grindstone. With everybody talking about impulse response reverb, we decided
to endow ours with the same.
English
When finally our reverb was tweaked to deliver both breeds of effect, there
was still a problem: Should they be commercial or internet freebies, virtually all available impulse responses have about as much in common with a
real room as a Big Mac has with real food. And none of them sounded near
as good as our algorithmic reverb. So, what to do?
We searched everywhere for an exceptional impulse response and actually
found an engineer who had spent three years of his life pursuing this particular grail and had already produced an unbelievable library. He had even
developed his own post-processing software. Doubtless, a demigod among
designers! And we managed to sign him on. Exclusively, of course, much
to the chagrin of the competition.
The product approached perfection. Now all we needed was somebody to
notice.
The NAMM 2005 show was the breakthrough. Rumors about the world’s
best reverb spread like wildfire. Purists who were known to scoff at
$50,000 devices lay prostate before us, begging for an alpha version.
Now you enter the picture. Although Wizoo can’t hope to match the big
players’ publicity, and although your friends surely attempted to talk you
into buying a product sporting a better-known brand, you boldly decided to
go with the WizooVerb.
For that, we congratulate you and offer our heartfelt thanks. The rewards
for you will be great, because the WizooVerb more than makes good on the
performance promise: When you hear yours the first time, you will jettison
all your preconceptions about reverb.
Take our word for it. WizooVerb has brought tears of joy even to multiple
Grammy award-winning studio maestros. So break out the Kleenex!
On behalf of the team and everyone who had a hand in this miracle, here’s
wishing you lots of fun and success with WizooVerb.
Yours sincerely,
Best regards,
Peter Gorges

Wizoo Product Certification
Setting up the Stand Alone Version
The Stand Alone version of the WizooVerb W2 converts your PC into a
high-end reverb unit—especially practical when using Notebooks on stage.
On the Mac nothing special needs to be configured: the WizooVerb W2
Stand Alone always sends and recieves via the inputs and outputs of the
audio hardware chosen in the Mac OS X ‘Sound’ System preference.
Wizoo Product Certification
Be it a demo or full version, every Wizoo product must be certified before
you can use it. Certification serves to confirm that you are a legal user and
to enable your Wizoo product for use on your system.
If you want to certify a demonstration version, please proceed as described below, but
do not fill in the box for the certification code.
There is no need to install special programs or hardware for certification
purposes. All you need is a web browser or an e-mail program with Internet access.
The easiest option is to certify using the stand-alone version of WizooVerb
W2. This precludes pesky problems with the host software.
All plug-in versions are activated when you certify the stand-alone version of WizooVerb W2. You can try certifying using a WizooVerb plug-in, but depending on the host,
you may not be able to type characters into the plug-in’s certification panel.

3 Getting Started with WizooVerb
In this chapter you will become acquainted with the user interface’s main
features and learn how to load and store reverb programs.
The Control Features
WizooVerb W2’s central control element is its large, variable display. The
Page buttons at the top edge let you access different display pages. Most
have different functional panels that are accessed via the menu tabs at the
left edge.
At the lower edge of the display there are five parameter boxes. You will usually adjust their values using the knobs located below. Alternatively, you can
select values in the parameter boxes using the mouse, type in the target
value directly, and then confirm by pressing the ‰ key.
Depending on Page and functional panel, WizooVerb automatically assigns appropriate functions to the parameter boxes and knobs. The big
knob at the center is always assigned to the most important parameter. In
addition, you can grab and edit parameter values directly in the display on
some menu pages, for instance, in graphical editors and global settings.
Selection lists for all key operations appear at the right edge of the display to
facilitate the handling of WizooVerb W2. They make it easy for you to load,
store and delete data swiftly and easily. All lists may be organized in folders
and subordinate folders. Navigation is a piece of cake:
English
❖ To open a folder, double-click its name. You can also open folders by
clicking once directly on the folder icon.
❖ To quit a folder, scroll to the top within that folder and click the (..)
folder.
You’ll find a level meter on each side of WizooVerb W2 with controls located
below:
❖ The Input VU meter indicates the level of the unprocessed input signal.
The Input knob lets you adjust input sensitivity.
21
3 Getting Started with WizooVerb
❖ The Output VU meter indicates the level of the output signal, which
consists of the dry direct signal and/or the reverb signal. The Dry/Wet
knob lets you determine the mix or balance of the original and the processed (reverb) signals.
In addition, the panel’s input and output feature one Width knob each; it
adjusts the stereo width of the given signal.
For details on these functions see the chapter “Global Parameters” starting on
page 31.
[W2_Complete
Using Presets
A preset is a complete reverb program comprising the HDIR model as
well as all parameters: When you load a preset, WizooVerb W2 is configured in the setup it was in when this preset was saved.
Because the Presets Page is many users’ first choice of interface, it opens
automatically when WizooVerb W2 is launched. The panel is divided into
two areas:
The Info window on the left displays information on the loaded preset—
name, reverb time, type, file size, a description and the format of the corresponding HDIR model.
22
Using Presets
The preset selection list on the right affords you access to basic functions

4 Basics
In the following chapter we will look at how natural reverberation is created and how it can be emulated. Armed with this basic knowledge, you
will be better equipped to understand the explanations of parameters provided in subsequent chapters.
Methods of Generating Reverb
Until recently there were only few ways of simulating reverberation. Electro-acoustical methods such as the traditional spring reverb and reverb
plate aside, there are only two processes of practical value that deliver a
sufficient level of sound quality:
❖ Algorithmic reverb (also known as digital reverb): Based on complex de-
lay and all-pass filter circuits, this method has been used since the ’80s
in all reverb devices and most plug-ins. Algorithmic reverb works in
real time and can be adjusted flexibly, but never sounds entirely natural
even with the most expensive devices and plug-ins.
❖ Impulse response: This procedure is based on the recorded impulse re-
sponse of real rooms. Because the underlying mathematical processes
require oodles of computing power, it has only been in recent years that
computers were powerful enough to generate reverb in real time using
this principle. This breed of plug-in has been around since the late
’90s. Impulse response-driven reverb can sound wonderfully lifelike,
but editing options are very limited, and it requires lots of computing
power.
An impulse response is sort of an acoustical snapshot that captures the sound of a
room. The standard procedure is to send a sine signal through a speaker and sweep
it through the room whose sound you want to capture, and record the room sound
using microphones and digital equipment. Once the sine sweep is computed out of
the recording, the original room sound can be simulated via a set of mathematical
equations far too complex for mere mortals to consider.

4 Basics
Each of the two methods has its advantages. In WizooVerb, the two are so
closely intertwined that they afford you unheard-of options. And you are
free to choose the best of the bunch according to situation and desired result.
How WizooVerb Works
WizooVerb W2’s means and methods are quite different from the aforementioned procedures. It combines a highly advanced form of impulse response (HDIR; short for High Definition Impulse Response) with a proprietary approach to reverb generation (AIR, short for Acoustic Impulse
Rendition). As you will soon discover, these two new technologies complement each other remarkably well.
❖ A sophisticated standard for recording and processing impulse re-
sponse, HDIR ensures rooms are captured in all their sonic details.
HDIR outperforms conventional impulse response across the full
stretch of the recording and processing chain. That’s why it features so
prominently in WizooVerb. A special process is applied to analyze the
impulse response’s metadata, which WizooVerb W2 then uses to maximize sound quality and afford you comprehensive editing options. We
have coined the term “HDIR models” to describe the impulse responses integrated in WizooVerb.
Certified engineer Ralph Kessler invested years of research to develop HDIR. He
analyzed all the adverse effects that arise when recording and post-processing impulse responses, and developed special methods to eliminate them. He also succeeded in extracting metadata from impulse responses.
❖ Developed by Wizoo, AIR is a reverb-generating process that enables
select portions of impulse responses to be re-synthesized and then processed in real time. AIR generates reverb of hitherto unrivalled quality
and flexibility.
Though AIR is not based on the conventional combination of delay and all-pass
filter circuits, it offers all the advantages of the algorithmic method, including
placing a far lighter load on computers.

What Causes Reverberation?
Courtesy of this combination, WizooVerb W2 offers unprecedented processing options and surprising flexibility, as well as outstanding sound
quality.
The following of rule of thumb applies to WizooVerb: HDIR is the best choice when you
want to accurately replicate a real room (natural reverb). AIR is the preferred choice if
you want more editing options or need to conserve computer performance. Because
the principles behind the modes are so different, each offers very different creative
possibilities that are explained fully in the following chapters. In beiden Modi haben
Sie prinzipbedingt unterschiedliche kreative Möglichkeiten, die später noch weiter
unten ausführlich erklärt werden.
What Causes Reverberation?
Let’s review some basic acoustics.
When a sound source sends an acoustic wave out into a room, it is reflected as well as absorbed by the walls, ceiling and floor, as well as by all
the objects in the room.
Reflection: If the direct path between the sound source and listener is unobstructed, the direct sound arrives at the ear first. It is followed by early re-
flections that rapidly condense to form the tail. Reverberation can be divided into three phases, depending on the time of the reflections’ arrival.
Though one phase morphs smoothly and seamlessly into the next, each
can have a varying impact on our perceptions:
English
❖ Reflections up to about 20 ms are largely perceived as unpleasant color-
ing.
❖ Reflections up about 20 to 50 ms serve to create a sense of spatiality,
that is, a room.
❖ After about 50 ms, reflections usually have condensed to create the dif-
fuse tail.
Absorption: Sound loses energy with every reflection so that towards the
end the tail tapers off gently. The time elapsing between the direct sound
and the tail’s decay is called reverberation or reverb time.
27
4 Basics
In technically accurate terms, reverb time is defined as the length of time it takes for
the sound level to decay to 60 dB below the initial level.
Energy loss increases as the frequency rises, so reverb time is shorter for
high frequencies. The reverb gradually loses brightness, becoming quite
dark at the end of the tail. Hence the room’s absorptive properties not only
influence the duration but also the tone of the reverb.
Factors influencing our perception of the size and state of the room are
also important. Key factors include:
❖ Reverb time: It is instrumental in shaping our perception of the room’s
size because we associate long reverberation times with big rooms.
❖ Early reflections: On closer examination, early reflections’ loudness and
the time it takes for them to condense play important roles.
So, what does all this have to do with WizooVerb? Plenty: WizooVerb W2 is
not only based on these principles, it also makes use of them in unprecedented ways:
❖ WizooVerb W2 offers a remarkably intuitive approach to editing the
structures of natural reverberation.
❖ All of WizooVerb W2’s processing options are attuned specifically to
the listener’s perceptions.
The following chapters provide an in-depth introduction to these processing options and their effect on the listener’s subjective perceptions.

Music and Reverb
Music and Reverb
HDIR models are particularly rich in detail and realistic. Rather than creating artificial reverb like conventional effects, HDIR actually replicates
rooms with stunning accuracy. For this reason, it delivers the best results
when the style or genre of music matches the room it would actually be
performed in.
An example should clarify this point: WizooVerb W2 lets you “play” drums
in a classical concert hall. Like in reality, though, the results may disappoint because concert halls were built for orchestras rather than drums!
Every HDIR model in WizooVerb W2 is patterned after a specific room
and for a specific type of performance. To achieve swiftly satisfying results,
get into the habit of selecting suitable models. If you can’t find what you’re
looking for in the HDIR archive, you can create a room of your own devising thanks to AIR technology.
