Aphex Aural Exciter Plug-In Guide 8
Switches
Drive Switch
The Drive switch offers two settings, Normal
(+6 dB) and High (+18 dB). This sets the input
sensitivity to the harmonics generator. In gen-
eral, this switch will be left in the Normal posi-
tion. However, weak signals may require more
gain, in which case you should place this switch
in the High position.
Use the Drive meter to determine if the signal
gain needs to be increased. When the meter
level stays in the green area (never rising into
the yellow area), then the input signal is too
low. Raise the input sensitivity by toggling the
Drive switch to High.
The switch illuminates when Drive is set to
High.
Density Switch
The Density switch determines the amount of
harmonics generated by choosing one of two
different harmonics generator algorithms.
When set on High, the output from the har-
monic generator expands low level signals and
compresses the highest peaks. This setting pro-
vides a higher density of harmonics with better
control of peak levels.
If you have problems with clipping when set-
ting the Mix control, switch Density to High for
better peak level control.
Since the amount of harmonics is dependent on
the input level, start with the switch set to Nor-
mal. Switch to High if you still want a greater
density of harmonics after the input level is set.
The switch illuminates when Density is set to
High.
Ax Switch
The Ax switch gives you the choice of turning
the Aural Excitement process On or Off. The Ax
switch illuminates when Ax is engaged, con-
firming that the effect is On.
Unlike the Bypass switch, the audio signal from
the input does travel through the DSP algorithm
on the way to the output whenever Ax is Off.
This means that the SPR effect can still be active,
by switching Ax Off and SPR On.
Solo Switch
When engaged, the Solo switch gives you a
choice of auditioning the Aural Excitement sig-
nal without the main audio, The switch illumi-
nates when Solo is active.
As an application for the Solo switch, select Solo
to return the pure effect back to the mixing con-
sole for precise memory control of the Aural Ex-
citement signal only.
SPR Switch
The SPR switch controls the Spectral Phase Re-
fractor effect. This effect is independent of all
other controls or switches, except Bypass. The
switch illuminates when SPR is engaged, con-
firming that SPR is On. SPR processes the main
audio signal in such a way that bass frequencies
(up to 150 Hz) lead phase in relation to the rest
of the spectrum.
If your input signal is in the yellow area of
the Drive meter, this indicates you are re-
ceiving an acceptable signal level. Switch-
ing the Drive switch to High in this instance
could cause clipping.
