Using phase scopes

You can display a phase scope in the Channel Meters and Hardware Meters windows to find phase cancellation among the channels in an audio file. For more information on channel meters, see Using the channel meters on page 44. For more information on hardware meters, see Using the hardware meters on page 111.

Right-click the Channel Meters or Hardware Meters window and choose Show Phase Scope from the shortcut menu to toggle the display of the phase scope.

To change the display, right-click the Channel Meters or Hardware Meters window, choose Phase Scope Style from the shortcut menu, and then choose a setting from the submenu:

Style

Description

Lissajous - XY Plot

Displays the right and left channels plotted along the X and Y axes of the

 

graph.

 

 

Lissajous - Rotated

Displays the right and left channels plotted along the X and Y axes of the

 

graph. This setting is identical to the Lissajous - XY Plot setting, but the graph is

 

rotated 45 degrees.

 

 

Polar - Linear Plot

Displays the right and left channels plotted vertically on the graph.

 

 

Polar - Circular Plot

Displays the right and left channels plotted on a circular graph.

 

 

Using the mono-compatibility meters

You can display a mono-compatibility meter in the Channel Meters and Hardware Meters windows to detect correlations or differences between the channels of a file that can cause phase cancellation when downmixing to mono. For more information on channel meters, see Using the channel meters on page 44. For more information on hardware meters, see Using the hardware meters on page 111.

Right-click the Channel Meters or Hardware Meters window and choose Show Mono-Compatibility Meter from the shortcut menu to toggle the display of the mono-compatibility meter.

When the channels are similar, the right (or top) half of the meter is illuminated:

When the channels exhibit phase cancellations, the left (or bottom) half of the meter is illuminated:
