Spectral Pan Display, with audio moving from left to right
Spectral Pan Display works well in conjunction with the Center Channel Extractor effect. That effect lets you isolate
frequencies that are common to both the left and right channels (in other words, sounds that are panned center). In
some cases, you may find that the audio you want to isolate is slightly off-center. You can use Spectral Pan Display
to determine the actual pan position of the audio you want to isolate and enter that value in the Center Channel
Extractor to improve the quality of the extraction. You can also use the Center Channel Extractor to boost the signal
of audio at a particular pan position. For more information, see "Center Channel Extractor effect" on page 163.
Another effect that works well with Spectral Pan Display is the Pan/Expand effect. The Pan/Expand effect lets you
shift the center channel of a stereo waveform and expand or narrow the stereo separation of the left and right
channels. For more information, see "Pan/Expand effect (Edit View only)" on page 166.

About Spectral Phase Display
Spectral Phase Display shows the phase difference, in degrees, between the left and right channels. For example, if
any frequency is 180˚ out of phase, Spectral Phase Display shows bright patches near the +/-180˚ marks. You can
modify display settings for Spectral Phase Display using the Spectral Controls panel.
Audio that is more than 90˚ out of phase creates problems when summing to mono and may sound odd in stereo. To
help you determine how much audio is out of phase, Adobe Audition displays lines at the 90˚ marks by default.
