With Inner Cone enabled, you can dene an inner falloff angle (Inner Angle). Within a cone which
has this angle as its vertex, the emitted sound has maximum volume; it then gently quietens, until it
reaches the surface of the cone dened by the outer angle, where the volume is zero. The permissible
values for the inner angle lie between 0° and 180°, but cannot exceed the value for the outer angle.
Falloff, Inner Distance, Outer Distance
The type of falloff is only effective between Inner Distance and Outer
Distance.
The optional falloff values for the loudspeaker dene the linear range of the emitted sound.
Additionally a type of falloff can be selected. Inner Distance and Outer Distance dene the start and
end of the falloff. The Falloff setting controls how the sound is to decrease over the falloff distance.
None
The volume of the loudspeaker does not decrease with distance. This behavior is not particularly
realistic and is only included for the sake of completeness. This option is unsuitable for inclusion in
surround sound information, since no spatial data can be calculated from it.
Linear
Generates an even, linear reduction of the volume over distance. The falloff begins at the Inner Distance
value and decreases constantly, until it reaches 0 at Outer Distance.
Inverse
Creates a quick falloff to 0%. This leads to a gentler pickup characteristic if a microphone is placed
within the falloff range of the loudspeaker.
Inverse Square
This is the most natural kind of falloff, which best reects reality. It is even softer than Inverse.
Inverse Cubic
Creates an extremely gentle falloff, which reaches maximum volume only briey after
Inner Distance.
