Hi, My appologies for what is probably a naive and confused question... I need to allow multiple programs/processes to take data from the same audio device at the same time. My initial imprtession is that audio devices are still set up only to allow one process to access them at a time. Is there some way to allow multiple processes to take input from the same audio device at the same time? A playback analogy might be how normally you can't have two processes play8ing data at the same time, but ARTS can take multiple audio streams and then play them out throug the one device. Many thanks for any advice you can give... robert -- ==================================================================== Robert Ross -------------------------------------------------------------------- Mail FB3, Mathematik-Informatik Deptartment of Mathematics Universität Bremen & Computer Science Postfach 330 440 University of Bremen 28334 Bremen P.O.
