MIT's KEMAR HRTF data (1994) are free to use without restriction provided the authors are cited (710 positions, 44.1 kHz); the Viking HRTF dataset v2 on Zenodo (2020) is licensed CC BY 4.0 in its record metadata and distributed as SOFA files plus 3D scans. Terms for third-party SOFA conversions of KEMAR were not readable (SOFA hosts refused connections to producer).
