Question using 7.1.2 plugins for ambisonics ?

Hey everyone,

since the Dolby Atmos Production Suite isn't coming to Windows anytime soon, my only option for immersive audio is using ambisonics right now. What really bothers me though, is the fact, that many VST effects & reverbs support Atmos bed tracks, but not ambisonics.

I'm mostly interested in using Reverb plugins and could probably decode FOA to 7.1.2 with RØDE Soundfield. But how would I convert 7.1.2 back to ambisonics?

I know there are commercial decoders available from Harpex, Penteo and BlueRipple. But they're anything but cheap and I'd rather spend that money on Verberate Immersive or one of the Exponential Audio 3D Reverbs once they're on sale.

If I understand what you want, I would encode back to B-Format with an encoder/panner like the IEM MultiEncoder. https://plugins.iem.at/download/

Unless you need the special effect it will provide, you can easily avoid to pass through the ambisonic encoding/decoding process by using compatible plugins.

Since apparently you don't need to produce Atmos datas but "only" want to use the same spatial arrangement, Reaper's ReaSurround can be set perfectly to 7.1.2 space or whatever you want.
You may also take a look at my "acousmodules" plugins which are all compatible with it :
There is also commercial products like the GRM-Tools Space series or the more expensive Flux Spat Revolution.

Otherwise, like Kewl has written, the IEM AllRADecoder + MultiEncoder set to 7th order can preserve most of the work that you will do with your multichannel effects ;-)
