Ambisonic Decoding for non-spherical speaker array?

Author 2 Subscribed Users |

Hello.

I am wondering what the best approach is for decoding 3rd-order ambisonics to a non-spherical speaker setup.

for the HOA Decoder settings, is there more information where i can read about how to determine what method, optimization, and normalization i should be using for different circumstances?

Thank you.

Hi,

Short answer : the default and recommended method is the “energy-preserving decoder”.

I have gathered more infos in the attached patcher.
I will try to progressively improve the documentation. (but HOA decoder is a complex topic…)

All the best,
T.

This is incredibly helpful Thibaut, thank you for putting it together.

I’m going to digest and do some tests now.

(really appreciated your talk in Montreal at SAT a few weeks ago btw, was wonderful to hear you demo the techniques in that space)
