At the moment, the distributed versions (SuperCollider and JSFX plug-ins) don't support HOA. That includes binaural HOA decoders. An HOA version is in development, and we have run some concerts here in Seattle using some of these features. 2. The FOA ATK HRTF decoders are -3D for the decoders generated from the measured IRCAM Listen and CIPIC HRTF sets -2D for the decoders generated from the simple Duda Spherical Head model You can read about these decoders in the documentation for the SuperCollider version of the ATK here <http://doc.sccode.org/Classes/FoaDecoderKernel.html>. Repeated from that page regarding the Spherical Head model: With no pinnae and no body, elevation cues are not present. No pinnae + No body = 2D You'll need to remember, this is only the final rendering (decoding). B-format soundfields are 3D, the ATK's Duda Model decoder, just doesn't reproduce elevation cues. You can rotate the soundfield with VR-head tracking as you normally would/should.... Clear?
