The HRIR/HRTF Sets Shipped With SSR
SSR ships with two different sets of HRIRs/HRTFs, which are named based on the manikins on which they were measured (FABIAN and KEMAR).
The reference for the FABIAN measurement is
Alexander Lindau and Stefan Weinzierl. FABIAN - Schnelle Erfassung binauraler Raumimpulsantworten in mehreren Freiheitsgraden. In Fortschritte der Akustik, DAGA Stuttgart, 2007.
and the document
hrirs_fabian_documentation.pdf provides further information.
The reference for the KEMAR measurement is
Hagen Wierstorf, Matthias Geier, Alexander Raake, and Sascha Spors. A Free Database of Head-Related Impulse Response Measurements in the Horizontal Plane with Multiple Distances. In 130th Convention of the Audio Engineering Society (AES), May 2011.
whereby the low-frequency extension from
https://github.com/spatialaudio/lf-corrected-kemar-hrtfs (commit 5b5ec8) has been
applied to the KEMAR HRTFs.
