I've used the VVTetraVST plugin too, with FuMa->Ambix conversion, using the actual calibration files for the mic. The Ambeo seems to give slightly better results, but I'm willing to have more goes with VVTetraVST is you think it's significant.
The way I have the routing in Reaper is that the track with the 4-channel content send to parent channels 1-4 (but I've tried 1-16 too, just for luck, not that it should make any difference), to the master which is 16-channels in, 21 out. I'm using a MadiFace interface, and each output in Reaper is definitely going to the right channel and the right speaker. (I've tested this by having a mono source and routing it individually to each speaker.) The speakers are all powered Genelecs. I've calibrated them such that the same signal routed to any of them comes to within 1dB SPL of each other at the centre of the hemisphere. The speakers are in phase by virtue of being connected by way of a Studer Desk which takes MADI input and outputs on 32 XLR outs. I'm not entirely sure I follow the speaker coordinates question. The way I've done it is by putting radius, azimuth and elevation for each in a CSV file to ADT, which then calculates the right encoding configuration for that particular array. I trust that ADT and ambix decoder are doing the right things, e.g. that "speaker 1 is at radius 4.5m and, 0 degrees azimuth and -22.5 degrees elevation" is actually receiving the right mix of signals. But this is useful, thank you. I wouldn't be surprised to find that I've overlooked something, so any more things to check are welcome! - martin On 5 July 2017 at 23:48, Steven Boardman <boardroomout...@gmail.com> wrote: > Ok. > > Just to rule out, only use the ambeo plugin for the ambeo.
