The Goniometer Pro is a great tool to display the phase differences between two audio channels (resulting from the similarity of the signals). You get a scope reading of the selected speaker's signals to get an overview of the amount of out-of-phase signal parts.
The correlation indicator offers a simple solution to check the mono compatibility of a stereo signal. It also lets you identify unwanted phase shifts or polarity inversions. We have optimized the Vienna Suite Goniometer Pro to work at the lowest possible CPU demand, which allows you to use it as a constant controlling device for your mixes.
Oversampling allows for a precise signal interpretation and the GLOW feature enables you to control the signal without constant observation of the display.
SPEAKER 1 / Phase Invert: Select Channel 1 speaker. Click the Phase Invert icon to invert the phase of channel 1.
SPEAKER 2 / Phase Invert: Select Channel 2 speaker. Click the Phase Invert icon to invert the phase of channel 2.
SWAP: Swap Channel 1 and 2 outputs.
Display window: Shows the Goniometer interpretation of the chosen signals.
Correlation Glow Meter (A): Displays the correlation of the input signal in a range from -1 to +1. The determined values mean the following:
+1: Identical signals in both channels.
1 to 0: The input signals are (more or less) mono-compatible.
0: The input signals are totally uncorrelated (or a channel is missing).
0 to -1: The input signals are not mono-compatible.
-1: The input signals are identical, but with polarity inversion on one channel (no mono compatibility).
Correlation Glow Time (A): Lets you adjust the time for the glowing effect. At "0 s", older data will fade very quickly. At "10 s", older data will fade out slower and the Correlation Glow Meter will show a longer time bracket of the input signal. Clicking on the Correlation Glow Meter will reset the Goniometer Glow.
ANALOG: Activates the interpolated display of the signal in the Goniometer (similar to analog goniometers with a cathode ray tube).
x4: Quadruple the amount of drawn points.
NORM: Normalizes gain before metering.
Goniometer Glow Time (B): Lets you adjust the time for the glowing of the correlation value in the goniometer display. At "0 s", only the current value is visible. At "10 s", you can see the progression of the correlation degree over a period of 10 seconds. Clicking on the Goniometer display will reset the Goniometer Glow.
