Phase Correlation Meter¶
About Phase Correlation Meter¶
The phase correlation meter shows the phase relationship between the left and the right audio channel in a stereo recording and is an important tool when mastering stereo recordings.
How to read the Phase Correlation Meter¶
If both channels contain exactly the same signal, the phase correlation meter will show a vertical line. If one channel is exactly the opposite of the other channel, the phase correlation meter shows a horizontal line. Normal stereo recordings will show a cloud of dots spread out vertically and horizontally (see the picture below).
In a properly mastered recording, the cloud of dots should not be wider than it is tall and the correlation value indicated in the gauge at the bottom should be positive.
