Even if "Wave Field Synthesis" is a general term, we must be more than careful
because this precise expression (behind its general sounding) have been chosen
by researchers in the 80s to specifically design an application.

I usually try to use "sound field reproduction" (seems absurd, but its not my
fault! WFS is locaked with a given way to think). Now you can say that "WFS" is
"sound field reproduction" and Ambisonics is "sound field reproduction".

You can run Ambisonic by yourself with Pure-Data (there is some fresh object ...
like "ambipan"?). My personnal ambisonic patch have been developped using the
mtx (matrices) object in Pure-Data. Those objects have been developped by IEM
for ambisonic.
