I guess networking several instances of pd will give you all the channels you need.cheers,Rick
OK, seems IOhannes already mentioned this in more comprehensive context: Wave Field Simulation. There are lots of papers out there, like this one from last year's AES conference: http://www.mattmontag.com/media/2011/10/AES-131-e-brief-Montag-Wave-Field-Synthesis-by-Multiple-Line-Arrays.pdf
I also doubt that Pd would be the best tool for this... networked computers may have a latency that just messes up all the precise timing. I guess you will need something timecoded, and/or low latency hardware, the latter possibly being so called "processors" or "speaker drivers" which are DSPs specifically designed to drive speaker arrays.
