I’m using a SoundField SPS200. You’ll find documentation of two of the installations I’ve done in collaboration with Jeremy Welsh here: http://trondlossius.no/works/56-the-atmospherics-ii---flags-flames-smoke-bridges http://trondlossius.no/works/57-the-atmospherics-iii---till-it-rains-im-gonna-stay-inside For both of these I used 16 speakers, 8 near the floor and 8 near the ceiling.It’s not enough vertical coverage to give full 3D (there are holes below and above), but I’m thinking of this approach more as a vertical “widening” of the horizon as compared to 2D layouts. We’ve just opened a new installation at the art museum in Førde, Sogn & Fjordane. I don’t have any audio/video documentation online, but Jeremy has posted a number of photos from all of the “Atmospherics” installations that we’ve done together, including this one: http://jewelsh.blogspot.no/p/the-atmospherics.html The latest work was installed in a large white cube at the museum, and the vertical dimension of the sound really comes into its own here. At the same time the rectangular shape of the space, and the amount of reverb and a number of acoustic oddities posed major challenges, and I ended up having to build a number of 4 channel filter and eq JSFX effects for Reaper that I used extensively to adjust for this. Still, the reverberation in this space makes localisation in the mid and low frequency range much more blurry than in the previous installations.
