Defining the Speaker Array
↓ To define the speaker positions
THE SIMULATION TOOLS
The near field determines what happens when sound gets within
the minimum source distance. If the near field is on flip and the
sound source enters the minimum sound distance, the sounds
will flip from one speaker to the next, while when near field is
set at omni, the sound will appear to come from all of the
speakers equally.
The Space Array comes with an input for a B-format sound
source. Such sound sources have 4 outputs which contain
sound signals for x,y,z, and omni directions. This input can be
used for interactive sounds within the soundscape.
The minimum source distance represents the virtual distance at
which sounds will be played back at unity gain. The manner in
which objects within the minimum source distance are played
back is altered by the sound object near field setting.
Figure out how many speakers are in the array. Add each
speaker and adjust locations of the speakers from an arbitrary
origin point found at (0,0,0). The listener is assumed to be at
0,0,0. If the listener is located elsewhere, enter the location of
the listener.
• Click Speakers.
A new dialogue box will appear, allowing the array to be
defined (Figure 28).
