Structure defining a reverb environment.< BR >
For more indepth descriptions of the reverb properties under win32, please see the EAX2 and EAX3< BR >
documentation at http://developer.creative.com/ under the 'downloads' section.< BR >
If they do not have the EAX3 documentation, then most information can be attained from< BR >
the EAX2 documentation, as EAX3 only adds some more parameters and functionality on top of EAX2.< BR >
Note the default reverb properties are the same as the FSOUND_PRESET_GENERIC preset.< BR >
Note that integer values that typically range from -10,000 to 1000 are represented in decibels, and are of a logarithmic scale, not linear, wheras float values are typically linear.< BR >
PORTABILITY: Each member has the platform it supports in braces ie (win32/xbox). < BR >
Some reverb parameters are only supported in win32 and some only on xbox. If all parameters are set then the reverb should product a similar effect on either platform.< BR >
The numerical values listed below are the maximum, minimum and default values for each variable respectively.< BR >
