1 In Edit View, choose Window > Phase Analysis.
2 In Waveform Display of Edit View, click a point, select a range, or start playback.
If you select a range, Adobe Audition analyzes the center point of the range.

By default, the graph shows stereo channels on the horizontal axis and phase information on the vertical axis.
In-phase audio appears in the top half of the graph; out-of-phase audio appears in the bottom half.
To zoom in on the graph, use the mouse wheel or right-click a ruler and drag the magnifying glass icon. (See “Zoom
phase and frequency graphs” on page 95.)
The colored ball shows the overall stereo and phase location of audio. The ball turns red for out-of-phase audio,
green for in-phase audio, and yellow for borderline audio.
The white outline shows the percentage of samples in each channel that are in- or out-of-phase, reflecting the
width of the stereo image.

If it’s very broad, the file will sound significantly different in mono.
The colored tracer lines indicate whether the waveform is more in phase (blue) or out of phase (red).
