You set up a lot of speakers and a decent computer. Two decent computers if your room isn't ideal.

>Music Research Centre's Arthur Sykes Rymer Auditorium is equiped with a sixteen speaker Ambisonic rig. This rig cosists of four high speakers, eight horizontal speakers and four speakers below the audience in the air conditioning plenum duct, which was designed to allow for this. The rig is driven by a Firewire audio interface (Focusrite Saffire Pro) which can be accessed from computers positioned in the performance area via Firewire. This rig can do up to third order horizontal with first order height.
