Hi Fernando,

I see you use SuperCollider,

I'm always using two band decoders (except for the subs of course). I
use ADT to create them, compile to SuperCollider UGens and use them from
within my diffusion program.

Maybe you would like to check out the SC-HOA quark where we interface with
the ADT.
I also implemented recently the Binaural decoder from the IEM plugins in
the SC-HOA quark.
Which is fun for monitoring.
