CORE front panel overview (continued)
Following are descriptions of CoreReLation Phase Analyzer
’s front panel sections and controls.
8. Glass Display Section
CORE’s glass display provides 2 controls, goniometer (vectorscope) and output meter, as follows:
A. Power Button
- The power button turns the audio goniometer (vectorscope) on/off. The button
is green when ON and red when OFF. Turning off the audio goniometer when not in use will
reduce cpu/dsp use.
B. Goniometer
- A goniometer is often included in analog audio equipment to display a
Lissajous
figure which shows the amount of stereo (that is, phase differences) in a dual-channel signal. It
allows the sound technician to adjust for optimal stereo and determine the makeup of errors
such as an inverted signal. Source:

(S = Stereo: L = Left; M = Middle; R = Right).
C. Hue (Color) Knob
- The Hue Knob allows you to change the hue of the audio goniometer to any
color in the full visible spectrum. [Ctrl]-click (Win) or [Cmd]-click (Mac) to return to the default
green color.
D. Audio Output Meter
- The Audio Output Meter is available in PEAK and VU (RMS) mode.
In PEAK Mode, the meter response is
0 ms for both rise and fall, which
means that this mode provides the
most accurate representation of the
signal level over time. Since the fall
time is 0 ms, it could be quite
distracting to the eyes to watch the
meters in PEAK mode. The peak
segment (the topmost LED segment,
indicating the highest level) will
remain lit until you click anywhere on
the meter (not the PEAK or VU text)
to reset the red clip lights.
The VU Mode simulates the behavior
of analog meters and shows the RMS
(Root Mean Square) value of the
signal. Since the RMS value is an
"average" of the signal level over time
it's not suited for detecting fast
transients in the sound. Rather, VU
meters are useful for monitoring the
overall loudness of the signal. In VU
Mode, the meter response is 300
ms/20 dB for both attack and release.
There is no peak segment in the
meter.

E. PEAK and VU Toggle Text
- By default, the audio output meter is set to PEAK mode (orange
numbers). Click on the VU text to change the meter to VU/RMS mode (blue numbers) and on
the PEAK text to return to PEAK mode. Click anywhere on the meter to reset clip lights.
