Space: Location and Movement
The spatial position of sound is one of the most important elements in our experience of sound.
Moving Sound Sources vs. Stationary Loudspeakers
Sound sources often move in the real world (e.g. a passing train, a swooping bird).
By using multiple loudspeakers we can reintroduce the impression of positioning and movement for sounds.
The most common setup is to have two loudspeakers, and this arrangement is known as stereo.
This type of setup is so common that most people simply refer to their music system as a ‘stereo’.
