Dataset of head-related transfer functions measured with a circular loudspeaker array

Abstract

In this paper, we describe a dataset of head-related transfer functions (HRTFs) measured at the Research Institute of Electrical Communications, Tohoku University. The current dataset includes HRTFs for 105 subjects at 72 azimuths × 13 elevations of spherical coordinates. Anthropometric data for 39 subjects are also included. The measurement and postprocessing methods are outlined in this paper. These data will be freely accessible for nonprofit academic purposes via the Internet. Moreover, this dataset will be included in an international joint project to gather several HRTF datasets in a unified data format.
