Abstract

A freely available collection of Head-Related Impulse Response (HRIR) measurements is introduced. The impulse responses were acquired in an anechoic chamber using a KEMAR manikin at four different loud- speaker 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. Besides the raw HRIRs also datasets are available which have been compensated for the use with specific headphone models.

Supplementary Material

The database was published in the MAT-File format at http://dev.qu.tu-berlin.de/projects/measurements/. That address is no longer available, and the original files are now published at 10.5281/zenodo.4459911.

The database has been converted into the SOFA format in the meantime and published under 10.5281/zenodo.55418.

Vera Erbes created a short version of the 3 m HRTF with low frequency corrections. This might be the best data set to start with for daily usage.

The easiest way to access the HRTFs in the SOFA format is most probably by using Matlab together with the SOFA API for Matlab and the get_ir() function from the Sound Field Synthesis Toolbox.
