Energizer (plug-in)
The Energizer belongs to the so-called psycho-acoustic processors genre. These
devices are used in the studio, acoustic irradiation, and restoration areas in order to
enhance the sound.
An effect like this usually can only be partially achieved with standard methods like
equalizing since an equalizer can only compile the frequency parts that are already in
the signal. Additionally an excessive increase in the signal (of the highs) increases the
chances of hissing.
With bass the problem often arises that for each device in an analog processing chain
(for example, tapedeck, mixing desk, pre-amp) slightly delays the signal compared to
the remaining spectrum. This type of phase lag cannot be restored with an EQ and
increasing the depth often results in a washed-out and feebler sound.
Psycho-acoustic devices are based on our hearing's ability to perceive attributes like
"freshness", "liveliness" and "naturalness" in a recording as a result of various
parameters. One of them is the harmony spectrum. The mid and high frequency
ranges of a loudly played instrument are richer than those of a quietly played
instrument. The "Exciter" tries to imitate this property with artificial harmonies.
However, this type of method cannot function statically as the noise and low-level
signals will be influenced otherwise.
The order in which individual frequencies are heard is just as important for lively
sound.
The psycho-acoustic method used in the Energizer is based on a combination of
frequency-dependent phase correction, additional harmonics creation and recognition
of so-called transients (short signal peaks).
The Energizer is subdivided into a bass and middle/high area. In both of these areas,
the audio can be enhanced independently of one another.
The parameters of the Energizer
The available effect presets cover typical areas of usage and are already set up as
presets in order to, for example, format a CD for playback on the car radio, use as a
soundtrack for your home entertainment system or for restoring distorted frequency
response curves of old records. The Energizer can have a drastic effect on the sound
even if only small changes are made to the parameters. So that you know which
