AES Convention 145 · Paper 455 · October 2018

Abstract

Spatial audio implementations with binaural playback benefit from personalized HRTF sets. Thus access to an efficient procedure for capturing individual Head Related Transfer Functions (HRTF) is beneficial for media production as well as for research and development in the ?eld. In the newly established Immersive Audio Lab at Hamburg University of Applied Sciences we implemented a fast HRTF measurement procedure in a 33-channel loudspeaker dome, utilizing the Multiple Exponential Sweep Method (MESM) introduced by Majdak, Balazs, and Laback [1]. One measurement of about 4 minutes results in a set of 289 discrete HRIRs, covering 360° in the horizontal plane and roughly -15°...90° elevation.
