Sounds that you hear within an enclosed space such as a
movie theater or concert hall can be classified as direct
sound, reflected sound (early reflections) or reverberative
sound (reverberation). When we hear these sounds, we get
a sense of the size and type of the space.
By reproducing early reflections, reverberation and other
sound characteristics, the digital surround processor
recreates the acoustics of particular spaces. When combined
with the digital equalizer, unique "sound fields" can be
produced.

The transition over time of direct sound, early reflections, and
reverberation can be graphed as follows:

Note
Since each sound field is determined by both fixed and
adjustable parameters, sound fields will not sound the same
even when all adjustable parameters are equal.
