Thanks for all the responses. Much appreciated. I'll re-phrase the question in light of some of the answers I've been given.
I will be using third-order Ambisonics. My aim mostly is to experiment to get a good sense of what is possible with Ambisonics with height. I have experimented successfully with 8-channel planar Ambisonics some time ago. My primary intent is to spatialise multiple monophonic (synthesised) sources using 3rd-order Ambisonics spatialisation, and the playback of mixed sources (spatialised monphonic and stereophonic sources as well as B-format 4-channel recordings.) At this moment in time, I have the opportunity to deploy (next week) a 16-channel array, so I would like some advice on a configuration that would be a good start to experiment with Ambisonics with height. Someone suggested that I consult the wikipedia page on Ambisonics. That is indeed where I got the idea that an "upper hemisphere" setup might be suitable, since I only have on this occasion 16 speakers. There is however no suggestion as to what a suitable hemispherical configuration might be for a 16-speaker array, which is why I asked my original question. So let me ask a new question. Given the constraint that I can only use 16 speakers at the moment, and that I need to deploy this next week, can somehow point me in the direction of what might be a suitable and reasonable geometric configuration to try out? It seems to me that the only really practical options here are two stacked rings (stacked octagons) or a hemisphere. I would have thought that the hemisphere would be the better choice, and in my scenario, a full lighting rig allows me theoretically speaking to have speakers at the required positions. Again, thank you for all the responses. - martin On 8 February 2016 at 15:19, Martin Dupras <[email protected]> wrote: > Hi, > > I'm intending to try setting up a 16-speaker Ambisonics array next > week in a small TV studio.
