Aphex Aural Exciter Plug-In Guide 12
To insert Aural Exciter on a track:
■ Click the Insert Selector on the track and se-
lect the plug-in that you want to use.
To remove Aural Exciter from a track:
■ Click the Insert Selector and choose No Insert.
Setting the Gain Structure
If the input material has a very high peak-to-
peak level and no additional headroom for Ex-
citer effects, use the Level fader to adjust the sig-
nal level to avoid clipping.
When using digital audio as a sound source,
such as a CD Player with S/PDIF outputs, there is
a very high peak-to-peak level because the mate-
rial on the CD is optimized for the best signal-
to-noise performance. In this situation the Level
fader can be used to adjust the signal level to
gain additional headroom.
In an analog based system you will have the
same headroom problem when using a very
high peak-to-peak level signal.
Using the Level fader to adjust for more head-
room is also useful when restoring older record-
ings.
For optimal performance keep the peak hold
meter of the Drive meter inside the yellow area.
The harder you drive the Exciter, the more Ex-
citer enhancement you generate. If you cannot
get the Drive meter to register in the yellow area,
try setting the Drive switch to High.
Information on Clipping
Your ears are usually a better judge of when a
signal is clipping than the VU meter. Non-peri-
odic clipped transients have to be driven ex-
tremely hard for it to be heard as clipping. Do
not assume that if your drive signal is “too high”
the Drive meter indicates brief moments of clip-
ping.
The Exciter’s harmonics generator has a “mask-
ing effect” on a clipped drive signal. You would
have to drive the harmonic generator very hard
before you would actually hear clipping.
Optimizing the Aural Exciter
Effects
When using the Aural Exciter, the output signal
level has to be equal to the input signal level
plus the enhanced Exciter effect. The dynamic
characteristics of the harmonic generator used
in the Aural Exciter plug-in are based on a com-
plex algorithm that includes the signal peak
level, the averaged steady state level, and the dy-
namic characteristics.
Unlike an EQ, which adds a constant boost in
the high end, the Aural Exciter enhancement is
added into the input signal is such a way that
the average signal level will be virtually un-
changed.
