Ok lets have a proximity off ! One of the things that interests me most in the work Im doing is creating proximity illusions. One member of this board asked my why I would choose WFS over HOA for the horizontal plane and my answer was that WFS could create more effective proximity illusions. However it occurs to me I haven't really heard a very high order ambisonic system (say 200+ speakers) - I have heard ambisonics on the 48 speaker system at Sarc and didn't if I'm honest hear much I would consider an effective proximity illusion. I have also heard my own humble single line array WFS system which was better but still not totally satisfactory- but others have bought reports back from Ircam of "voices right in front of them" . So my question is to those that have heard both WFS and HOA systems (not theory - actually heard) - which in your ear was able to create the most effective proximity illusions ? Also has anyone heard the haunted mansion WFS system at Disney ?
if the wfs you have available allows it, bend it into a circle and use the sound scape renderer to get an a/b comparison of HOA vs. WFS. matthias and sascha have shown it to me on their 56ch circular test array at t-labs. i don't remember now if i did get to hear focused sources in HOA, but i believe SSR can do it.
if you actually get the chance to try that on your own system, be sure to report your findings to the ssr authors - such feedback is rare, and i'm sure they'll appreciate it.
