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.
