Description

This SOFA Conventions is similar to SimpleFreeFieldHRIR. The most apparent difference is the DataType, which is TF. This Conventions was requested to cover the needs coming from HRTF simulations where results are given as complex values in the frequency domain for some discrete frequencies.
