A similar uestion has been answered recently on this same mailing list while talking about flanger ( which in fact is a modulated delay line ). Without more info and possibly a block diagram or a code snippet there is little we can do to help you. Giulio

I think the problem that I will refer to is already well know and please forgive me my ignorance if that’s the case. When I modulate the delay time, I experience some glitch/alias which is not pleasant. With an integer index base buffer access I hear less alias but more glitch. If I use interpolation for buffer access I experience less glitch and more alias. Im a bit frustrated at the moment. I would like to ask to this list if there is any relatively simple solution for this problem.
