IDirectSoundFXEcho8 Interface

' ***************************************************************************************
' IDirectSoundFXEcho8 Interface
' The IDirectSoundFXEcho8 interface is used to set and retrieve effect parameters on a
' buffer that supports echo.
' This interface is obtained by calling IDirectSoundBuffer8::GetObjectInPath on the buffer
' that supports the effect.
