Using CoreReLation Phase Analyzer
(Out of Phase)
Following are examples of
out of phase
readings between the Phase Correlation Meter and Goniometer. We
recommend using the Phase Correlation Meter in conjunction with Goniometer for a reliable indication for mono
compatibility.
Out of Phase
A phase cancelled track will be centered on the horizontal S axis. As shown above, the phase correlation meter
is sitting around -0.5 (red zone) and the goniometer is displaying a short and wide shape and centered along the
horizontal S axis. Also, the outer edges of the shape almost extend past the first inner circle. This is a clear
indication that the stereo field is wider than normal. In this state, the mix is out of phase and certain sounds may
get attenuated (quieter) or canceled when the entire mix is summed into a mono signal. This should be avoided.
Out of Phase (Horizontal S Axis)
Here is an extreme example of phasing issues, in which the phase correlation meter is sitting to the far left at -1
(red zone) and the goniometer is a thin shape centered on the horizontal S axis. This occurs when the left and
right channels are entirely out of phase, which we induced by inverting the phase of the right channel for
illustration purposes. In these cases the left channel is positive when right channel is negative and vice versa.
This is rarely the case on an entire mix (master bus), but you may find these issues on individual mix channels,
which can be corrected by inverting the phase of the left or right channel.
Basic Rule: The shorter and wider the goniometer shapes, the worse the mono compatibility.
