Creating FreeFieldHRTF

New page

This conventions defines free-field HRTFs stored as transfer functions in the spherical-harmonics domain, measured with an omnidirectional source for a single listener.

Based on [[SimpleFreeFieldHRTF]], the only difference is that the HRTFs are in a spatially continuous representation.

The conventions is defined in AES69-2020 (SOFA 2.0).
