New page

The convention is an extension of [[SimpleFreeFieldHRIR]] in order to consider more complex data sets described in spatially continuous representation. Each HRTF direction corresponds to an emitter (instead of a source position), and a consistent measurement for a single listener and all directions is described by a set of the emitter positions (instead of source positions) surrounding the listener.

The data type 'FIR-E' is used (instead of 'FIR' as in [[SimpleFreeFieldHRIR]]).

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