HRIRs were measured for each subject for a regular latitude-longitude distribution (15° elevation and variable azimuthal resolution) and for at least 12 key Ambisonic loudspeaker configurations: Octahedron (x3 orientations), Cube, Bi-Rectangle (x3 orientations), Icosehedron, 7-Design, 26pt Lebedev Grid, Pentakis Icosedodecahedron and 50pt Lebedev Grid. They were taken using Genelec 8010s at a radius of 1.2m from the center of the subject's head.
BRIRs were measured for each subject for a 50pt Lebedev Grid Configuration. They were taken using Genelec 8030/40s at a radius of 1.5m from the centre of the subject's head.
Headphone Responces were measured for beyerdynamic DT990 headphones.

Audio data is available in 44.1K - 16bit, 48K - 24bit and 96K - 24bit .wav and AES 69 SOFA format. Measurements are labeled by azimuth and elevation in degrees accurate to 1 decimal place. Azimuth is measured anti-clockwise (to the left) about the horizontal plane. 0° marks directly in front of the subject. Elevation is measured above (positive) and below (negative) the horizontal plane. These data sets are specifically supported the Ambix Ambisonic decoder configuration files found here. By default, the config. files were designed to load measurements at 48KHz.

All data was recorded and developed at The Audio Lab, Department of Electronic Engineering, University of York, UK by Cal Armstrong, Lewis Thresh and Gavin Kearney. For any further details please get in touch.
