[Openal] Sound effect problem

[frankmail007]

Maybe I should ask another question. What is the best way to emulate a
release phrase of a instrument? For example, I have a 5s sound sample. But I
only play it for 2s, I currently use a timer to reduce the volume of the
source to mimic the release effect of a instrument. Is there any better
solution to implement the same effect?
