Default value
null
If set to an 18-element list, this value customizes reverbration settings for this sound only. A null or non-numeric value for any setting will select its default. Please see the EAX2 documentation at http://developer.creative.com/ for indepth information about these settings.
Here’s a rundown of some of the terms: Direct refers to the amount of effect when the sound is on a direct path to the listener. Obstruction is when an object is blocking the direct path but there are other ways for the sound to reach the listener. Occlusion means the sound is on the other side of a wall, and mostly blocked. Exclusion means the sound is on the other side of a wall, but a doorway or window is allowing it to pass through to the listener. You can use a little of each of these effects to increase realism.
1 Direct (-10,000 to 1,000) default = 0
direct path level (at low and mid frequencies)
2 DirectHF (-10,000 to 0) default = 0
relative direct path level at high frequencies
3 Room (-10,000 to 1,000) default = 0
room effect level (at low and mid frequencies)
4 Room HF (-10,000 to 0) default = 0
relative room effect level at high frequencies
5 Obstruction (-10,000 to 0) default = 0
main obstruction control (attenuation at high frequencies)
6 ObstructionLFRatio (0.0 to 1.0) default = 0.0
obstruction low-frequency level re. main control
7 Occlusion (-10,000 to 0) default = 0
main occlusion control (attenuation at high frequencies)
8 OcclusionLFRatio (0.0 to 1.0) default = 0.25
occlusion low-frequency level re. main control
9 OcclusionRoomRatio (0.0 to 10.0) default = 1.5
relative occlusion control for room effect
10 OcclusionDirectRatio (0.0 to 10.0) default = 1.0
relative occlusion control for direct path
11 Exclusion (-10,000 to 0) default = 0
main exlusion control (attenuation at high frequencies)
12 ExclusionLFRatio (0.0 to 1.0) default = 1.0
exclusion low-frequency level re. main control
13 OutsideVolumeHF (-10,000 to 0) default = 0
outside sound cone level at high frequencies
14 DopplerFactor (0.0 to 10.0) default = 0.0
like DS3D flDopplerFactor but per source
15 RolloffFactor (0.0 to 10.0) default = 0.0
like DS3D flRolloffFactor but per source
16 RoomRolloffFactor (0.0 to 10.0) default = 0.0
like DS3D flRolloffFactor but for room effect
17 AirAbsorptionFactor (0.0 to 10.0) default = 1.0
multiplies AirAbsorptionHF member of environment reverb properties.
18 Flags default = 7
Bit flags that modify the behavior of properties
- 1 - Automatic setting of ‘Direct’ due to distance from listener
- 2 - Automatic setting of ‘Room’ due to distance from listener
- 4 - Automatic setting of ‘RoomHF’ due to distance from listener
