DB/SoundProviderPreferences

World of Warcraft uses the FMod Sound Library by Firelite Technologies ("http://www.fmod.org/"). The data stored in this table corresponds with the struct FMOD_REVERB_PROPERTIES in the FMod API.

For more indepth descriptions of these properties under win32, you'll need to check the EAX2 and EAX3 documentation at "http://developer.creative.com/" under the 'downloads' section.

However, chances are you will not need to ever touch anything in this DBC.
