Description
This SOFA convention set is similar to SimpleFreeFieldHRIR. The only difference is the DataType, which is TF, not FIR. SimpleFreeFieldTF 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.
Version 1.0
This version follows the conventions SimpleFreeFieldHRIR (version 1.0) standardized in AES69-2015. Note that SimpleFreeFieldTF 1.0, in contrast to SimpleFreeFieldHRIR 1.0, has not been included in the standard, thus it is declared as stable.
