What is the default orientation of the dummy head in the HRTF?

[WeiXipin]

Hello, I am using the HRTF-related interfaces and I am unsure about the orientation of the default dummy head, specifically, which coordinate the face is facing. For example, if I set

orientation = Rotation3D([0.0, 0.0], "yz", degrees=True)

does this mean that the face is oriented towards the positive x direction?

Hi @WeiXipin , I am not completely sure, so please make sure to check what I say here.
I think the MIT Kemar sofa file follows the SimpleFreeFieldHRIR SOFA convention
Please make sure to read it carefully.
If that is correct, the the head is facing towards the positive x direction and the top of the head is in the positive z direction.
