Analyzing phase

In Edit View, you can use the Phase Analysis window to analyze phase either statically for
a selected range or dynamically during playback. You should analyze phase only for stereo
waveforms, as phase differences don’t exist in mono waveforms. Phase analysis can reveal
out-of-phase channels, which you can correct with the Invert command. (See “Inverting
and reversing audio” on page 106.)

The Phase Analysis window includes a Lissajou Plot graph. By default, this graph displays
phase differences between the left and right channels as follows:

A mono waveform appears as a diagonal line ascending from left to right.

A right-channel-only waveform appears as a horizontal line.

A left-channel-only waveform appears as a vertical line.

A completely out-of-phase stereo waveform appears as a diagonal line descending from
left to right.

A typical stereo waveform appears as many wavy lines descending from right to left.

A stereo waveform with wide separation appears as many wavy lines extending in all
directions.

To zoom in on a particular area of the Phase Analysis graph, use the horizontal and
vertical rulers. See “Zooming graphs for frequency and phase analysis” on page 122.
