# Anechoic HRIRs from the KEMAR manikin with different distances¶

UPDATE: a new version converted to the SOFA format is available at 10.5281/zenodo.55418. In addition, V. Erbes created a version of the 3m measurement, that is corrected in low frequency and shortened and available at https://github.com/spatialaudio/lf-corrected-kemar-hrtfs.

These measurements were done in November 2010 in the anechoic chamber of the Institut für Technische Akustik at Technische Universität Berlin. The impulse responses were acquired using a KEMAR manikin at four different loudspeaker distances - 3 m, 2 m, 1 m and 0.5 m - reaching from the far field to the near field. The loudspeaker was positioned at ear height and the manikin was rotated with a high-precision stepper motor in one degree increments.
In addition to the impulse responses there are also headphone compensation filters available for AKG K601, AKG K271 and Sennheiser HD 25 headphones.

The naming scheme of the impulse response files is:

QU_KEMAR_anechoic_<headphone name>_<distance>.<format>
where <headphone name> stands for the headphone the impulse response is compensated for. Files without any headphone name are the impulse responses not compensated for any headphone.

The measurements were presented at the 130th AES Convention in London on May 13th, 2011 and are described in detail in the corresponding paper: source:2010-11-kemar-anechoic/doc/wierstorf2011_QU_KEMAR_anechoic.pdf.
