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.
