Even if you set them up to exactly the same value, you can't rely on them matching exactly, because even the finest crystal oscillators aren't infinitely accurate. The only common situation I can think of where you do NOT have this problem is in studios, between local audio interfaces synchronized via wordclock or similar. However, one can usually get away with just inserting or dropping a single sample frame every once in a while, so I'm kind of wondering if you even have the right nominal sample rates... For example, 44 kHz vs the standard 44.1 kHz would be a problem, and would probably require proper resampling to avoid constant audible artifacts. -- //David Olofson - Consultant, Developer, Artist, Open Source Advocate .--- Games, examples, libraries, scripting, sound, music, graphics ---. | http://consulting.olofson.net http://olofsonarcade.com | '---------------------------------------------------------------------'
