Correlation Meter




The correlation meter is an instrument that measures the phase correlation between two audio channels. The phase correlation is the degree of alignment or synchronization between the waveforms of two audio signals. It is important to check the phase correlation between two audio channels to ensure a good stereo imaging and sound quality.


The correlation meter of Pinguin Audio Meter 4.5 Pro is a simple and effective tool that shows the phase correlation between two audio channels using a scale from -1 to +1. The scale indicates the following values:


  • +1: Perfect positive correlation, which means that the two audio channels are in phase and have the same polarity.



  • 0: No correlation, which means that the two audio channels are independent and have no relation.



  • -1: Perfect negative correlation, which means that the two audio channels are out of phase and have opposite polarity.



The ideal value for phase correlation is +1, which indicates a coherent and balanced stereo image. Values close to 0 indicate a wide and spacious stereo image, but may also cause some cancellation or interference between the two audio channels. Values close to -1 indicate a reversed and inverted stereo image, which may cause severe cancellation or distortion between the two audio channels.


To use the correlation meter of Pinguin Audio Meter 4.5 Pro, you just need to select the input source for the meter, and observe the value displayed on the scale. You can also switch between different views and modes for the meter, such as:

Stereo Meter (Phase Scope = Gonio Meter)




The stereo meter is an instrument that monitors the stereo field width and phase correlation of audio signals in a X-Y view. The stereo field width is the degree of separation or difference between the left and right audio channels. The phase correlation is the degree of alignment or synchronization between the waveforms of two audio signals.


The stereo meter of Pinguin Audio Meter 4.5 Pro is also known as a phase scope or a gonio meter. It shows the stereo field width and phase correlation of audio signals using a Lissajous curve, which is a shape formed by plotting two sine waves on a X-Y plane. The shape of the Lissajous curve indicates the following values:


  • A straight line from bottom left to top right: Perfect positive correlation, which means that the two audio channels are in phase and have the same polarity. This indicates a mono signal or a very narrow stereo image.



  • A straight line from top left to bottom right: Perfect negative correlation, which means that the two audio channels are out of phase and have opposite polarity. This indicates a reversed and inverted stereo image, which may cause severe cancellation or distortion between the two audio channels.



  • A circle: No correlation, which means that the two audio channels are independent and have no relation. This indicates a very wide and spacious stereo image, but may also cause some cancellation or interference between the two audio channels.



  • An ellipse: Partial correlation, which means that the two audio channels have some degree of phase alignment and polarity difference. This indicates a normal and balanced stereo image, with a variable width and depth.



To use the stereo meter of Pinguin Audio Meter 4.5 Pro, you just need to select the input source for the meter, and observe the shape of the Lissajous curve displayed on the X-Y view. You can also switch between different views and modes for the meter, such as:
