I did. Between us, I much prefer the sound of spaced omni for reverberation, and first order is way too imprecise as well. I’ve successfully done stereo to quad to third order in a few pieces, using the fluffy of ambisonic to my advantage over discreet sources to avoid phantom on sharp stuff, and it works really well. in this case, 8 IRs to 16 channel TOA.
My code review question is more in line with this thread and with my old C_polluted_with_Cpp habits of syntax. So the code review bit is more about peak of FFT transforms (and maybe I should have a bus and run 8 synths that I offset as in the post) or with my SClang syntax (which might be improved by some tricks I am unaware of)
I’ll post a new version with my favourite modulation at the input in a few hours, I’m going to the multichannel studio now.
