Expanding works by subtracting or adding differing amounts of right and left channel
signals, so sounds occurring on the right or left are cut or boosted. You can alter both of
these elements dynamically over time by using the respective graph.

Using the Stereo Field Rotate effect
This effect lets you rotate the stereo field of an audio file. The stereo field denotes where in
space instruments or other sources are placed within the left and right images of a stereo
waveform. By manipulating the Rotation graph, you can affect how the instruments seem
to move over time.
To use the Stereo Field Rotate effect:

Using the Center Channel Extractor effect
The Center Channel Extractor effect keeps or removes frequencies that are common to
both the left and right channels—in other words, sounds that are panned center. Often
voice, bass, and lead instruments are recorded this way. As a result, you can use this effect
to bring up the volume of the vocals, lead bass, or kick drum or remove any of them from
the stereo mix.
