Psycho-acoustic effects
EXCITER:
An exciter works with psycho-acoustic principles to add artificially
generated overtones to the original signal, thereby increasing its presence and
loudness (the subjective volume impression) without any significant increase of
the signal level.
ENHANCER:
The enhancer works like a dynamic pitch equalizer. Its effectiveness
depends on the associated high frequencies and the intensity of the input signal.
ULTRA BASS:
This awesome combination of sub-harmonic processor,
bass exciter, and limiter adds a final touch to your music production.
STEREO IMAGER:
This effect is used to process stereo main signals. The signal is
first subdivided into middle and side signal (MS Matrix). Both parts can then be
amplified when desired and placed on the stereo image.
ULTRA WIDE:
This effect is suitable to pep up speaker systems with an especially
broad stereo image.
BINAURALIZER:
The binauralizer also extends the stereo image. Additionally,
it compensates for inter-channel cross talk of both speakers (left loudspeaker on
right ear and vice versa).

FILTER/EQ
FILTER/EQ
Filter/EQ effects
FILTER:
Filters, in general, influence the frequency response of a signal. A low
pass filter allows low frequencies to pass and suppresses high frequencies,
while a high pass filter allows high frequencies to pass and suppresses
low frequencies.
PARAMETRIC EQ:
The parametric equalizer is the most highly-developed
form of equalization. You can control the three parameters which define the
so-called gauss equalizer curve: bandwidth, frequency and amplitude boosting
or lowering.
GRAPHIC EQ:
Eight filter bands are arranged next to each other for this graphic
equalizer. In contrast to the parametric equalizer, frequency and bandwidth are
pre-determined here.
