IDirectSoundFXCompressor8 Interface

' ***************************************************************************************
' IDirectSoundFXCompressor8 Interface
' The IDirectSoundFXCompressor8 interface is used to set and retrieve effect parameters on
' a buffer that supports compression.
' This interface is obtained by calling IDirectSoundBuffer8::GetObjectInPath on the buffer
' that supports the effect.
