I'm an absolute newbie.  What I'm looking to do is have audio coming from an input source to one mono speaker.  Then decrease the volume to that speaker, increasing to the next.  When volume reaches zero on first speaker , it starts decreasing on speaker 2 and increasing on speaker three.  And so on.  This creates the effect of the song rotating around the four speakers.  Can this be done using the Beocreate 4CA, or a combination of other cards?  Any suggestions would be very helpful.  Many thanks, Tim

  In general this should be doable with a custom DSP program. I would try to use 4 signal generators with 90 degree phase offsets and modulate the incoming data with these. However, as you are "an absolute newbie" this is probably not a beginners project. SigmaStudio requires not just some knowledge about DSPs in general and the specific hardware, but also has a steep learning curve. Therefore, we only recommend this to users with at least some experience in DSP programming.
  Unfortunately I don't think there is some guide that you can just follow to implement this.
