Generally, the more you can see a "thread" shape, the more bass there is in the signal;
the more "spray-like" the display, the more high frequencies are in the signal.
Phase Correlation meter
At the bottom of the display, you will find a Phase Correlation meter, which shows the same
information but in a different way:
The green line shows the current phase correlation, while the two red lines show the
recent peak minimum and maximum values, respectively (these are the default colors,
which you can change).
With a mono signal, the meter would show +1, indicating that both channels are per-
fectly in phase.
Similarly, -1 indicates that the two channels are the same, but one is inverted.
Generally, for a "good" mix, the meter should show a value between 0 and +1.
Unlike the main Phasescope, the Phase Correlation meter is also available in "Analyze audio
selection" mode, showing an average value for the selected range.
Changing settings
You can define display colors, peak hold time, and the resolution or number of samples to
display from the Functions > Settings... menu.
The Phasescope meter can be found in the Meters menu of the Audio Files and Audio Mon-
tage Workspaces. It can be used either as a floating window, or docked in the Workspace
or the Control Window.

11.2.2 VU Meter
The vu-meter is used to display the peak and average loudness/decibel level of your Audio
File. It also displays the pan, or the balance between the left and right channels in a stereo
file.
The upper part of the level/pan meter window shows the peak level and average loudness,
in the following way:
The Peak Level meters display the peak levels of each channel, graphically and numeri-
cally. By default, the meter segments and numerical peak values are displayed in green
for low levels, yellow for levels between -6dB and -2dB, and red for levels above -2dB.
You can change both the colors and the range boundaries if you wish via the Level/Pan
Meter Settings dialog. This can be accessed through the Functions > Settings...
menu, or by using the icon.
