The Vienna Suite Goniometer is a great tool to display the phase differences between two audio channels (resulting from the similarity of the signals). You get a reading of the stereo width and the amount of out-of-phase signal parts.
The additional 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 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.
Display window: Shows the Goniometer interpretation of the chosen signals. The display is independent of the absolute level of the signal, the level of the signal is automatically adjusted in a big dynamic range (-50 dB to 0 dB).
Analog: Activates the interpolated display of the signal in the Goniometer (similar to analog goniometers with a cathode ray tube).
Detail: Activates the display of a second, brighter goniometer signal. This feature lets you observe the actual signal while using higher GLOW settings.
Clip: Activates the "Clipping" of signals, starting at 0 dB FS amplitude. This lets you judge whether and how a signal is clipping. Clearly, clipping stereo signals will show a rhombus shape in the goniometer display. If Clip is deactivated, the amplitude of the signal will be adjusted dynamically to an area below 0 dB FS.
Goniometer Glow (GON. GLOW): Lets you adjust the time for the glowing effect in the goniometer display. At "0", older data will fade very quickly. At "100", older data will fade out slower and the goniometer display will show a longer time bracket of the input signal. Clicking on the Goniometer display will reset the Goniometer Glow.
Correlation: 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 (COR. GLOW): Lets you adjust the time for the glowing of the correlation value in the goniometer display. At "0", only the current value is visible. At "100", you can see the progression of the correlation degree over a longer period of time. Clicking on the Goniometer display will reset the Correlation Glow.
Input Channel Selection: Select the input signals that will be analyzed. In a stereo track, only "L-R" will be available, a surround track will let you choose a signal pair from multiple input signals.
Level: Peak-Metering for both selected input signals.
