Thats what i get for editing ;D
i first wrote that it might not be your issue but then it really sounded exactly like the problems i had with making music. And it could have been since your making realtime sound.
The only thing that werent exact the same sounding where your clicks where i was experiencing more crackling sounds. ;D
But great that it worked out for you and thanks for the source. Maybe i try it out for making engine sounds.
