M-Audio WizooVerb W2 [26/132] How wizooverb works

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 re-

sult.

How WizooVerb Works

WizooVerb W2’s means and methods are quite different from the afore-

mentioned procedures. It combines a highly advanced form of impulse re-

sponse (HDIR; short for High Deﬁnition Impulse Response) with a pro-

prietary approach to reverb generation (AIR, short for Acoustic Impulse

Rendition). As you will soon discover, these two new technologies comple-

ment 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 maxi-

mize sound quality and afford you comprehensive editing options. We

have coined the term “HDIR models” to describe the impulse re-

sponses 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 im-

pulse responses, and developed special methods to eliminate them. He also suc-

ceeded 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 pro-

cessed 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.
