   I'll have to agree....

   All that would be needed is an "open" interface into the
   Yamaha DSP processors....your specific room environment is
   fed as a correction signal into their existing DSP
   processing.

   You would need a lot of (computer or otherwise) knobs, etc.
   to allow tuning for personal tastes to override any
   automation....most people don't really much care for a "flat"
   response generated by the automated equalizers of today...and
   I doubt if any computer would be able to satisfy everyone's
   ears.

   You can play around with this today if you have DSP hardware
   and a fast enough PC...all that is really needed is to take
   the algorithms and move it to VLSI to get the parts count
   down and speed up.  Anyone got a few megabucks?
