[STRUCTURE] 
[
    [DESCRIPTION]
    Structure defining a reverb environment.
    For more indepth descriptions of the reverb properties under win32, please see the EAX2 and EAX3
    documentation at http://developer.creative.com/ under the 'downloads' section.
    If they do not have the EAX3 documentation, then most information can be attained from
    the EAX2 documentation, as EAX3 only adds some more parameters and functionality on top of 
    EAX2.
    Note the default reverb properties are the same as the FSOUND_PRESET_GENERIC preset.
    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.
    PORTABILITY: Each member has the platform it supports in braces ie (win32/xbox).  
    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.
    Only Win32 supports the reverb api.
    
    The numerical values listed below are the maximum, minimum and default values for each variable respectively.

[STRUCTURE] 
[
    [DESCRIPTION]
    Structure defining the properties for a reverb source, related to a FSOUND channel.
    For more indepth descriptions of the reverb properties under win32, please see the EAX3
    documentation at http://developer.creative.com/ under the 'downloads' section.
    If they do not have the EAX3 documentation, then most information can be attained from
    the EAX2 documentation, as EAX3 only adds some more parameters and functionality on top of 
    EAX2.
    
    Note the default reverb properties are the same as the FSOUND_PRESET_GENERIC preset.
    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.
    PORTABILITY: Each member has the platform it supports in braces ie (win32/xbox).  
    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.
    Linux and FMODCE do not support the reverb api.
    
    The numerical values listed below are the maximum, minimum and default values for each variable respectively.
