Mixing first and third order ambisonics

Spat
#1

Hello,

I have one question about decoding multiple ambisonics orders. I have files containing 16 channels third order ambisonics, and 4 separate channels with reverb in first order. Would it be work connecting both to the same decoder (input 1-16 and 1-4):
spat5.hoa.decoder~ @order 3 @dimension 3D @outputs 16
Or would I need to have a separate decoder for first order content?
spat5.hoa.decoder~ @order 1 @dimension 3D @outputs 16
It saves lots of CPU to have only one.

Best,
Ruben

Hello,

Yes, that is OK to sum the 1st order stream with the 3rd order HOA stream.
(as long as they have the same normalization and channel sorting, of course)

Best,
T.
