Definition |
For region-based audio, an object of this DRM class specifies the range where the audio is attenuated to fade out at the boundary. |
|||||||||
|
Example(s) |
· Use of a 2D areal region to define a localized storm cell. If the listener is within the region, play the constant sound of rainfall. If the listener is outside the region, don't play the rainfall sound. At the edge of the region, the sound should not just turn itself off; it should gradually fade out as it recedes from the viewer. So a <DRM Fade Range> is attached to the <DRM Sound Instance>, defining the range at which the sound begins fading away and the range at which the sound has completely faded away. |
