Thanks for the advice, definitely useful. The speaker and room setup
are fixed, I can't change that at all, so I have to make the best of
it. I think I'll start with VBAP since it is easy, and seems lighter
than ambi. The sound environment that I am working on now will be
made of 6000 sounds moving around, so lightweight is good :)

for panning inside the array, nothing other than WFS will give you
a reasonable source image inside the room. often for ambisonics, you'd just xfade from the XYZ channels more
into the W (omni) channel within a certain radius. same with VBAP - just pan all speakers. (or turn spread all the way
up). NickOn Oct 6, 2008, at 12:33 PM, Thomas Grill wrote:
one more thing: If you want to position your virtual sound sources _inside_ the circle of speakers i am not sure if this is possible with ambisonics at all - and it's also difficult for VBAP depending on the triangulation it uses... you might want to check or manually
specify it. In such a case I personally would want to have some center speakers and would have two VBAP-driven rings (in the middle and on the periphery) between which i would do conventional panning. I once used that i the case of a planetarium where the audience is situated in a ring between the center and the circular wall. I had 3 center speakers facing to the wall, 5 peripheral speakers facing to the center and two subwoofers. all the best, ThomasAm 06.10.2008 um 06:39 schrieb Hans-Christoph Steiner:
So I am working on sound for a permanent installation involving 6 speakers in a large circular room. Are 6 speakers enough to do anything useful using ambisonics? Or am I better off using the simpler vbap?
I am just starting to understand the basics of ambisonics, thanks to Florian's intro. I will be programmatically controlling the
position of the samples, since it will be synced up with a video. So I don't think I really need the GUIs like cubemixer.Are there any simple, working demos of the IEM ambi stuff?
