@OP Instead of going through all this trouble, you can just use


ambifreeverb2 for 1oa, and https://www.brucewiggins.co.uk/?page_id=78

FdnReverb & from the IEM suite for 7oA (works with surround & ambisonics)

This is all documented here: https://docs.google.com/spreadsheets...x1TirK/pubhtml

You should NEVER have to do separate 5.1 and stereo mixes, UNLESS:
- you're doing dodgy things in 5.1 which won't translate well to stereo (like delays).
- You don't have a 5.1>2 downmixer. I have all the downmixers you want here https://github.com/junh1024/Reaper-Surround#downmixers if you don't mind lack of DPL2.


I've written a guide to mixing in surround here https://docs.google.com/document/d/e...KhqmELzHrt/pub

You could ALREADY downmix 2ch from 5.1. When you work in ambisonics, targeting 5.1 & 2ch, your mixes WILL sound worse, especially on your first few projects. In fact, when you generate stereo mixes from ambisonics, it guarantees you it will sound more same as surround, you will have less control and may sound worse than if you'd made a 5.1 initially, dependant on decoder.

Ambisonics is not detriment-free. When mixing for 5.1:
*Surrounds are overloaded with ITU 5.1 decoding
*You can never have a truly discrete center with 3oa since the resolution is 45*, but 5.1 ITU LCR is 30*
*A few other ones in https://docs.google.com/document/d/e...h.1jqhkjdh4bhw


Ambisonics gives you blank 3D canvas that you THINK you can place sounds anywhere, and will fold down to any speakers. You can place sounds anywhere, but we neither have speakers, nor ears everywhere. Ambisonics BLINDS you from real world human & speaker effects. Read these:

It quotes:

"Instruments panned partway between front and surround channels ... are subject to image instability and sounding split in two spectrally, so this is not generally a good position to use for primary sources."

This applies to ambisonics too.
