Apple Soundtrack Pro 3 - Manual (Page 25)

Setup for Stereo Mixing
By default, Soundtrack Pro is set up for stereo mixing. Most video editing suites use
nearfield monitors, which are speakers designed to be listened to at fairly close range.
Speakers should be at least a foot or two away from any walls to prevent early reflections
of sound that combine with and muddy the original sound.
Position the speakers as far from your listening position as they are from each other
(forming an equilateral triangle). For example, if the distance between the speakers is six
feet, you should place yourself six feet from each speaker. The apparent width of the
sound stage, or stereo image, increases as the distance between the speakers increases.
However, if the two speakers get too far apart, sound information appearing in the center
(between both speakers) starts to disappear.
