A Word About Our Controls
The control at left is typical of those found in the Pro GUI. To increase its
value, left click on the UP arrow. To decrease its value, left click on the
DOWN arrow. If you wish to quickly move to a value, you may click and
hold the UP or DOWN arrows and the control will scan to the end of its
range.
Another option is to double-click in the numeric field of the control which
will open up a dialogue where you can input the value you want. If the
value is not within the range of the controller, the controller will return to
the value within the accepted range that is closest to the requested value.
Controls that have a DOWN arrow but no UP arrow are drop down menus.
Usually, only 2 or 3 fixed options are available within this type of control. Click
the arrow, select the parameter and the drop down menu will automatically
close, having selected and displayed the new value.
Input Controls
The upper left corner of the Pro GUI hosts the Input settings for the
selected processor instance. Here, the input levels and left/right balance can
be adjusted, and there are also options for reversing the phase of both left
and right channels (Abs. Phase), swapping channels (L/R Reverse) summing
the left and right input to mono (Mono (Sum L+R)) and turning on and off
the phase rotator.
The input level range is adjustable between -36dB to +12dB with a setting
of 0dB referencing a peak input level of -12dBFS. Left/right channel balance
may be corrected by +/-12dB from 0dB (default).
High Pass Filter (HPF)
The purpose of a high pass filter is to remove or reduce
low frequency signals that are in the audio, but may not
be a desired part of the audio. Whatever frequency is
chosen as the Cutoff Frequency is the frequency at which
the response to undesired signals will be reduced by 3dB
(half power). The high pass response is that of a critically
damped fourth order filter.
The high pass filter (HPF) in the Aura1ip is designed a
bit differently than those found in other processors in that
it has the ability to reduce undesired low frequency noise in the sum (mono) signal, or the
difference (stereo) signal, or both. It does this by using its two different
high pass filter operating modes as explained next.
Stereo
– In the STEREO (St.) mode, the left hand control sets the
frequency where the filter begins to work on both sum and difference sig -
nals simultaneously. Because the effect is applied to both signals equally,
it is mathematically equivalent to the filter being operated in the left/right
