Introduction<\/h4>\n\n\n\n

The Viking HRTF dataset<\/strong> is a collection of head-related transfer functions (HRTFs) measured at the University of Iceland<\/a>. This includes full-sphere HRTFs measured on a dense spatial grid (1513 positions) with a KEMAR<\/a> mannequin with 20 different artificial left pinnae attached, one at a time. The artificial pinnae were previously obtained through a custom molding procedure from 20 different lifelike human heads (courtesy of Ernst Backman, <\/em>Saga Museum Reykjav\u00edk<\/em><\/a>).<\/p>\n\n\n\n

An overview of the methods and procedures of the HRTF measurement sessions can be found in the paper “The Viking HRTF dataset<\/a>”<\/em> presented at the 16th Sound & Music Computing Conference (May 2019, M\u00e1laga, Spain).<\/p>\n\n\n\n

This web page contains the post-processed HRIR and ITD data from the measurement sessions. You can get the whole dataset here<\/a>. A subset of the corresponding 3D pinna scans is also available here<\/a>. More morphological data will be added soon.<\/p>\n\n\n\n

Dataset Information<\/h4>\n\n\n\n

The dataset is organized in MATLAB data files (.mat), one per measurement session. The main directory contains the 20 .mat files corresponding to each of the 20 different custom-made pinnae (e.g. Subject_A.mat<\/em>). The control_sessions<\/em> directory includes the three control session files as described in the paper. Each .mat file contains two structures, HRIRs<\/strong><\/em> and ITD<\/strong><\/em>.<\/p>\n\n\n\n

HRIRs<\/em> is a 4-D matrix containing all the time-aligned impulse responses. The four dimensions of the matrix are:<\/p>\n\n\n\n
